1. Ankle and Subtalar Fusion

a. Description/Definition: Surgical fusion of the ankle or subtalar joint.

b. Occupational Relationship: Usually post-traumatic arthritis or residual deformity.

c. Specific Physical Exam Findings: Painful, limited range of motion of the joint(s). Possible fixed deformity.

d. Diagnostic Testing Procedures: Radiographs. Diagnostic injections, MRI, CT scan, and/or bone scan.

e. Surgical Indications/Considerations: All reasonable conservative measures have been exhausted and other reasonable surgical options have been seriously considered or implemented. Patient has disabling pain or deformity. Fusion is the procedure of choice for individuals with osteoarthritis who plan to return to physically demanding activities.

i. Prior to surgical intervention, the patient and treating physician should identify functional operative goals, and the likelihood of achieving improved ability to perform activities of daily living or work activities and the patient should agree to comply with the pre- and post-operative treatment plan including home exercise. The provider should be especially careful to make sure the patient understands the amount of post-operative therapy required and the length of partial- and full-disability expected post-operatively.

ii. Because smokers have a higher risk of delayed bone healing and post-operative costs, it is recommended that insurers cover a smoking cessation program peri-operatively. Physicians may monitor smoking cessation with laboratory tests such as cotinine levels for long-term cessation.

f. Operative Procedures. Open reduction internal fixation (ORIF) with possible bone grafting. External fixation may be used in some cases.

g. Post-Operative Treatment

i. An individualized rehabilitation program based upon communication between the surgeon and the therapist and using therapies as outlined in Therapeutic Procedures, Non-operative. In all cases, communication between the physician and therapist is important to the timing of weight-bearing, and exercise progressions.

ii. When boney union is achieved, treatment usually includes active therapy with or without passive therapy, including gait training and ADLs.

iii. Rocker bottom soles or shoe lifts may be required. A cast is usually in place for six to eight weeks followed by graduated weight-bearing. Modified duty may last up to four to six months.

iv. Return to work and restrictions after surgery may be made by an attending physician experienced in occupational medicine in consultation with the surgeon or by the surgeon.

2. Knee Fusion

a. Description/Definition: Surgical fusion of femur to the tibia at the knee joint.

b. Occupational Relationship: Usually from post-traumatic arthritis or deformity.

c. Specific Physical Exam Findings: Stiff, painful, sometime deformed limb at the knee joint.

d. Diagnostic Testing Procedures: Radiographs. MRI, CT, diagnostic injections or bone scan.

e. Surgical Indications/Considerations: All reasonable conservative measures have been exhausted and other reasonable surgical options have been seriously considered or implemented, e.g. failure of arthroplasty. Fusion is a consideration particularly in the young patient who desires a lifestyle that would subject the knee to high mechanical stresses. The patient should understand that the leg will be shortened and there may be difficulty with sitting in confined spaces, and climbing stairs. Although there is generally a painless knee, up to 50 percent of cases may have complications.

i. Prior to surgical intervention, the patient and treating physician should identify functional operative goals and the likelihood of achieving improved ability to perform activities of daily living or work activities and the patient should agree to comply with the pre- and post-operative treatment plan including home exercise. The provider should be especially careful to make sure the patient understands the amount of post-operative therapy required and the length of partial- and full-disability expected post-operatively.

ii. Because smokers have a higher risk of delayed bone healing and post-operative costs, it is recommended that insurers cover a smoking cessation program peri-operatively. Physicians may monitor smoking cessation with laboratory tests such as cotinine levels for long-term cessation.

f. Operative Procedures. Open reduction internal fixation (ORIF) with possible bone grafting. External fixation or intramedullary rodding may also be used.

g. Post-operative Treatment

i. An individualized rehabilitation program based upon communication between the surgeon and the therapist and using therapies as outlined in Therapeutic Procedures, Non-operative. In all cases, communication between the physician and therapist is important to the timing of weight-bearing, and exercise progressions.

ii. When boney union is achieved, treatment usually includes active therapy with or without passive therapy, including gait training and ADLs. Non weight-bearing or limited weight-bearing and modified duty may last up to four and six months.

iii. Return to work and restrictions after surgery may be made by an attending physician experienced in occupational medicine in consultation with the surgeon or by the surgeon.

3. Ankle Arthroplasty

a. Description/Definition: Prosthetic replacement of the articulating surfaces of the ankle joint.

b. Occupational Relationship: Usually from post-traumatic arthritis.

c. Specific Physical Exam Findings: Stiff, painful ankle. Limited range-of-motion of the ankle joint.

d. Diagnostic Testing Procedures: Radiographs, MRI, diagnostic injections, CT scan, bone scan.

e. Surgical Indications/Considerations: When pain interferes with ADLs, and all reasonable conservative measures have been exhausted and other reasonable surgical options have been considered or implemented. A very limited population of patients are appropriate for ankle arthroplasty.

i. Requirements include:

(a). Good bone quality;

(b). BMI less than 35;

(c). Non-smoker currently;

(d). Patient is 60 or older;

(e). No lower extremity neuropathy;

(f). Patient does not pursue physically demanding work or recreational activities.

ii. The following issues should be addressed when determining appropriateness for surgery: ankle laxity, bone alignment, surrounding soft tissue quality, vascular status, presence of avascular necrosis, history of open fracture or infection, motor dysfunction, and treatment of significant knee or hip pathology.

iii. Ankle implants are less successful than similar procedures in the knee or hip. There are no good studies comparing arthrodesis and ankle replacement. Patients with ankle fusions generally have good return to function and fewer complications than those with joint replacements. Re-operation rates may be higher in ankle arthroplasty than in ankle arthrodesis. Long-term performance beyond ten years for current devices is still unclear. Salvage procedures for ankle replacement include revision with stemmed implant or allograft fusion. Given these factors, an ankle arthroplasty requires prior authorization and a second opinion by a surgeon specializing in lower extremity surgery.

iv. Contraindications - severe osteoporosis, significant general disability due to other medical conditions, psychiatric issues.

v. In cases where surgery is contraindicated due to obesity, it may be appropriate to recommend a weight loss program if the patient is unsuccessful losing weight on their own. Coverage for weight loss would continue only for motivated patients who have demonstrated continual progress with weight loss.

vi. Prior to surgery, patients may be assessed for any associated mental health or low back pain issues that may affect rehabilitation.

vii. Prior to surgical intervention, the patient and treating physician should identify functional operative goals and the likelihood of achieving improved ability to perform activities of daily living or work activities and the patient should agree to comply with the pre- and post-operative treatment plan including home exercise. The provider should be especially careful to make sure the patient understands the amount of post-operative therapy required and the length of partial- and full-disability expected post-operatively.

viii. Because smokers have a higher risk of delayed bone healing and post-operative costs, it is recommended that insurers cover a smoking cessation program peri-operatively. Physicians may monitor smoking cessation with laboratory tests such as cotinine levels for long-term cessation.

f. Operative Procedures: Prosthetic replacement of the articular surfaces of the ankle; DVT prophylaxis is not always required but should be considered for patients who have any risk factors for thrombosis.

i. Complications include pulmonary embolism, infection, bony lysis, polyethylene wear, tibial loosening, instability, malalignment, stiffness, nerve-vessel injury, and peri-prosthetic fracture.

g. Post-Operative Treatment

i. An individualized rehabilitation program based upon communication between the surgeon and the therapist while using therapies as outlined in Therapeutic Procedures, Non-operative. In all cases, communication between the physician and therapist is important to the timing of weight-bearing, and exercise progressions.

ii. NSAIDs may be used for pain management after joint replacement. They have also been used to reduce heterotopic ossification after ankle arthroplasty. NSAIDs do reduce the radiographically documented heterotopic ossification in this setting, but there is some evidence (in literature on hip arthroplasty) that they do not improve functional outcomes and they may increase the risk of bleeding events in the post-operative period. Their routine use for prevention of heterotopic bone formation is not recommended.

iii. Treatment may include the following: bracing, active therapy with or without passive therapy, gait training, and ADLs. Rehabilitation post-operatively may need to be specifically focused based on the following problems: contracture, gastrocnemius muscle weakness, and foot and ankle malalignment. Thus, therapies may include braces, shoe lifts, orthoses, and electrical stimulation accompanied by focused therapy.

iv. In some cases aquatic therapy may be used. Refer to Therapeutic Procedures, Non-operative Aquatic Therapy. Pool exercises may be done initially under therapist's or surgeon's direction then progressed to an independent pool program.

v. Prior to revision surgery there should be an evaluation to rule out infection.

vi. Return to work and restrictions after surgery may be made by a treating physician experienced in occupational medicine in consultation with the surgeon or by the surgeon. Patient should be able to return to sedentary work within four to six weeks. Some patients may have permanent restrictions based on their job duties.

vii. Patients are usually seen annually after initial recovery to check plain x-rays for signs of loosening.

4. Knee Arthroplasty

a. Description/Definition: Prosthetic replacement of the articulating surfaces of the knee joint with or without robotic assistance.

b. Occupational Relationship: Usually from post-traumatic osteoarthritis.

c. Specific Physical Exam Findings: Stiff, painful knee, and possible effusion.

d. Diagnostic Testing Procedures: Radiographs.

e. Surgical Indications/Considerations: Severe osteoarthritis and all reasonable conservative measures have been exhausted and other reasonable surgical options have been considered or implemented. Significant changes such as advanced joint line narrowing are expected. Refer to subsection Aggravated Osteoarthritis.

i. Younger patients, less than 50 years of age, may be considered for unicompartmental replacement if there is little or no arthritis in the lateral compartment, there is no inflammatory disease and/or deformity and BMI is less than 35. They may be considered for lateral unicompartmental disease when the patient is not a candidate for osteotomy. Outcome is better for patients with social support.

ii. Contraindications - severe osteoporosis, significant general disability due to other medical conditions, psychiatric issues.

iii. In cases where surgery is contraindicated due to obesity, it may be appropriate to recommend a weight loss program if the patient is unsuccessful losing weight on their own. Coverage for weight loss would continue only for motivated patients who have demonstrated continual progress with weight loss. Furthermore several studies suggest that morbid obesity (BMI or = to 40) is associated with lower implant survivorship, lower functional outcome, and a higher rate of complications in TKA patients. Patients with BMI greater than 40 require a second expert surgical opinion.

iv. Prior to surgery, patients may be assessed for any associated mental health or low back pain issues that may affect rehabilitation.

v. Prior to surgical intervention, the patient and treating physician should identify functional operative goals and the likelihood of achieving improved ability to perform activities of daily living or work activities and the patient should agree to comply with the pre- and post-operative treatment plan including home exercise. The provider should be especially careful to make sure the patient understands the amount of post-operative therapy required and the length of partial- and full-disability expected post-operatively.

vi. Because smokers have a higher risk of delayed bone healing and post-operative costs, it is recommended that insurers cover a smoking cessation program peri-operatively. Physicians may monitor smoking cessation with laboratory tests such as cotinine levels for long-term cessation.

f. Operative Procedures: Prosthetic replacement of the articular surfaces of the knee; total or uni-compartmental with DVT prophylaxis. May include patellar resurfacing and computer assistance.

i. There is currently conflicting evidence on the effectiveness of patellar resurfacing. Isolated patellofemoral resurfacing is performed on patients under 60 only after diagnostic arthroscopy does not reveal any arthritic changes in other compartments. The diagnostic arthroscopy is generally performed at the same time as the resurfacing. Resurfacing may accompany a total knee replacement at the discretion of the surgeon.

ii. Computer guided implants are more likely to be correctly aligned. The overall long-term functional result using computer guidance is unclear. Decisions to use computer assisted methods depend on surgeon preference and age of the patient as it is more likely to have an impact on younger patients with longer expected use and wear of the implant. Alignment is only one of many factors that may affect the implant longevity.

iii. Complications occur in around 3 percent and include pulmonary embolism; infection, bony lysis, polyethylene wear, tibial loosening, instability, malalignment, stiffness, patellar tracking abnormality, nerve-vessel injury, and peri-prosthetic fracture.

g. Post-operative Treatment:

i. Anti coagulant therapy to prevent deep vein thrombosis. Refer to Therapeutic Procedures, Non-operative.

ii. NSAIDs may be used for pain management after joint replacement. They have also been used to reduce heterotopic ossification after knee arthroplasty. NSAIDs do reduce the radiographically documented heterotopic ossification in this setting, but there is some evidence (in literature on total hip arthroplasty) that they do not improve functional outcomes and they may increase the risk of bleeding events in the post-operative period. Their routine use for prevention of heterotopic bone formation is not recommended.

iii. An individualized rehabilitation program based upon communication between the surgeon and the therapist and using therapies as outlined in Therapeutic Procedures, Non-operative. In all cases, communication between the physician and therapist is important to the timing of weight-bearing, and exercise progressions.

iv. Treatment may include the following: bracing and active therapy with or without passive therapy. Rehabilitation post-operatively may need to be specifically focused based on the following problems: knee flexion contracture, quadriceps muscle weakness, knee flexion deficit, and foot, and ankle malalignment. Thus, therapies may include, knee braces, shoe lifts, orthoses, and electrical stimulation, accompanied by focused active therapy.

v. In some cases aquatic therapy may be used. Refer to Therapeutic Procedures, Non-operative, Aquatic Therapy. Pool exercises may be done initially under therapist's or surgeon's direction then progressed to an independent pool program.

vi. Continuous passive motion is frequently prescribed. The length of time it is used will depend on the patient and their ability to return to progressive exercise.

vii. Consider need for manipulation under anesthesia if there is less than 90 degrees of knee flexion after six weeks.

viii. Prior to revision surgery there should be an evaluation to rule out infection.

ix. Return to work and restrictions after surgery may be made by an attending physician experienced in occupational medicine in consultation with the surgeon or by the surgeon. Patient should be able to return to sedentary work within four to six weeks. Some patients may have permanent restrictions based on their job duties.

x. Patients are usually seen annually after initial recovery to check plain x-rays for signs of loosening.

5. Hip Arthroplasty

a. Description/Definition: Prosthetic replacement of the articulating surfaces of the hip joint. In some cases, hip resurfacing may be performed.

b. Occupational Relationship: Usually from post-traumatic arthritis, hip dislocations and femur or acetabular fractures. Patients with intracapsular femoral fractures have a risk of developing avascular necrosis of the femoral head requiring treatment months to years after the initial injury.

c. Specific Physical Exam Findings: Stiff, painful hip.

d. Diagnostic Testing Procedures: Standing pelvic radiographs demonstrating joint space narrowing to 2 mm or less, osteophytes or sclerosis at the joint. MRI may be ordered to rule out other more serious disease.

e. Surgical Indications/Considerations: Severe osteoarthritis and all reasonable conservative measures have been exhausted and other reasonable surgical options have been considered or implemented. Refer to subsection Aggravated Osteoarthritis.

i. Possible contraindications - inadequate bone density, prior hip surgery, and obesity.

ii. In cases where surgery is contraindicated due to obesity, it may be appropriate to recommend a weight loss program if the patient is unsuccessful losing weight on their own. Coverage for weight loss would continue only for motivated patients who have demonstrated continual progress with weight loss.

iii. Prior to surgery, patients may be assessed for any associated mental health or low back pain issues that may affect rehabilitation.

iv. For patients undergoing total hip arthroplasty, there is some evidence that a pre-operative exercise conditioning program, including aquatic and land-based exercise, results in quicker discharge to home than pre-operative education alone without an exercise program.

v. Aseptic loosening of the joint requiring revision surgery occurs in some patients. Prior to revision the joint should be checked to rule out possible infection which may require a bone scan as well as laboratory procedures, including a radiologically directed joint aspiration.

vi. Because smokers have a higher risk of non-union and post-operative costs, it is recommended that carriers cover a smoking cessation program peri-operatively. Physicians may monitor smoking cessation with laboratory tests such as cotinine levels for long-term cessation.

f. Operative Procedures: Prosthetic replacement of the articular surfaces of the hip, ceramic or metal prosthesis, with DVT prophylaxis. Ceramic prosthesis is more expensive; however, it is expected to have greater longevity and may be appropriate in some younger patients. Hip resurfacing, metal on metal, is an option for younger or active patients likely to out-live traditional total hip replacements.

i. Complications include, leg length inequality, deep venous thrombosis with possible pulmonary embolus, hip dislocation, possible renal effects, need for transfusions, future infection, need for revisions, fracture at implant site.

ii. The long-term benefit for computer assisted hip replacements is unknown. It may be useful in younger patients. Prior authorization is required.

iii. Robotic assisted surgery is considered experimental and not recommended due to technical difficulties.

g. Post-operative Treatment:

i. Anti coagulant therapy is used to prevent deep vein thrombosis. Refer to Therapeutic Procedures, Non-operative.

ii. NSAIDs may be used for pain management after joint replacement. They have also been used to reduce heterotopic ossification after hip arthroplasty. NSAIDs do reduce the radiographically documented heterotopic ossification in this setting, but there is some evidence that they do not improve functional outcomes and they may increase the risk of bleeding events in the post-operative period. Their routine use for prevention of heterotopic bone formation is not recommended.

iii. An individualized rehabilitation program based upon communication between the surgeon and the therapist and using the therapies as outlined in Therapeutic Procedures Non-operative. In all cases, communication between the physician and therapist is important to the timing of weight-bearing and exercise progressions.

iv. Treatment usually includes active therapy with or without passive therapy with emphasis on gait training with appropriate assistive devices. Patients with accelerated return to therapy appear to do better. Therapy should include training on the use of adaptive equipment and home and work site evaluation when appropriate.

(a). There is good evidence for the use of aquatic therapy. Refer to Therapeutic Procedures, Non-operative. Pool exercises may be done initially under a therapist's or surgeon's direction then progressed to an independent pool program.

(b). There is some evidence that, for patients older than 60, early multidisciplinary therapy may shorten hospital stay and improve activity level for those receiving hip replacement. Therefore, this may be used for selected patients.

v. Return to activities at four to six weeks with appropriate restrictions by the surgeon. Initially range of motion is usually restricted. Return to activity after full recovery depends on the surgical approach. Patients can usually lift, but jogging and other high impact activities are avoided.

vi. Helical CT or MRI with artifact minimization may be used to investigate prosthetic complications. The need for implant revision is determined by age, size of osteolytic lesion, type of lesion and functional status. Revision surgery may be performed by an orthopedic surgeon in cases with chronic pain and stiffness or difficulty with activities of daily living. Prior authorization is required and a second opinion by a surgeon with special expertise in hip/knee replacement surgery should usually be performed.

vii. Return to work and restrictions after surgery may be made by an attending physician experienced in occupational medicine in consultation with the surgeon or by the surgeon.

viii. Patients are usually seen annually after the initial recovery to check plain x-rays for signs of loosening.

6. Amputation

a. Description/Definition: Surgical removal of a portion of the lower extremity.

b. Occupational Relationship: Usually secondary to post-traumatic bone, soft tissue, vascular or neurologic compromise of part of the extremity.

c. Specific Physical Exam Findings: Non-useful or non-viable portion of the lower extremity.

d. Diagnostic Testing Procedures: Radiographs, vascular studies, MRI, bone scan.

e. Surgical Indications/Considerations: Non-useful or non-viable portion of the extremity.

i. Smoking may affect soft tissue healing through tissue hypoxia. Patients should be strongly encouraged to stop smoking and be provided with appropriate counseling by the physician.

f. Operative Procedures: Amputation.

g. Post-Operative Treatment

i. An individualized rehabilitation program based upon communication between the surgeon and the therapist and using therapies as outlined in Therapeutic Procedures, Non-operative.

ii. Rigid removable dressings are used initially.

iii. Therapies usually include active therapy with or without passive therapy for prosthetic fitting, construction and training, protected weight-bearing, training on the use of adaptive equipment, and home and jobsite evaluation. Temporary prosthetics are used initially with a final prosthesis fitted by the second year. Multiple fittings and trials may be necessary to assure the best functional result.

iv. For prosthesis with special adaptive devices, e.g. computerized prosthesis; prior authorization and a second opinion from a physician knowledgeable in prosthetic rehabilitation and who has a clear description of the patients expected job duties and daily living activities are required.

v. Return to work and restrictions after surgery may be made by an attending physician experienced in occupational medicine in consultation with the surgeon or by the surgeon.

7. Manipulation under anesthesia

a. Description/Definition: Passive range of motion of a joint under anesthesia.

b. Occupational Relationship: Joint stiffness that usually results from a traumatic injury, compensation related surgery, or other treatment.

c. Specific Physical Exam Findings: Joint stiffness in both active and passive modes.

d. Diagnostic Testing Procedures: Radiographs. CT, MRI, diagnostic injections.

e. Surgical Indications/Considerations: Consider if routine therapeutic modalities, including therapy and/or dynamic bracing, do not restore the degree of motion that should be expected after a reasonable period of time, usually at least 12 weeks.

f. Operative Treatment: Not applicable.

g. Post-Operative Treatment

i. An individualized rehabilitation program based upon communication between the surgeon and the therapist and using therapies as outlined in Therapeutic Procedures, Non-operative. Therapy includes a temporary increase in frequency of both active and passive therapy to maintain the range of motion gains from surgery;

ii. Continuous passive motion is frequently used post-operatively;

iii. Return to work and restrictions after surgery may be made by an attending physician experienced in occupational medicine in consultation with the surgeon or by the surgeon.

8. Osteotomy

a. Description/Definition: A reconstructive procedure involving the surgical cutting of bone for realignment. It is useful for patients that would benefit from realignment in lieu of total joint replacement.

b. Occupational Relationship: Post-traumatic arthritis or deformity.

c. Specific Physical Exam Findings: Painful decreased range of motion and/or deformity.

d. Diagnostic Testing Procedures: Radiographs, MRI scan, CT scan.

e. Surgical Indications/Considerations: Failure of non-surgical treatment when avoidance of total joint arthroplasty is desirable. For the knee, joint femoral osteotomy may be desirable for young or middle age patients with varus alignment and medial arthritis or valgus alignment and lateral compartment arthritis. High tibial osteotomy is also used for medial compartment arthritis. Multi-compartmental degeneration is a contraindication. Patients should have a range of motion of at least 90 degrees of knee flexion. For the ankle supra malleolar osteotomy may be appropriate. High body mass is a relative contraindication.

i. Because smokers have a higher risk of nonunion and post-operative costs, it is recommended that carriers cover a smoking cessation program peri-operatively. Physicians may monitor smoking cessation with laboratory tests such as cotinine levels for long-term cessation.

f. Operative Procedures: Peri-articular opening or closing wedge of bone, usually with grafting and internal or external fixation.

i. Complications: new fractures, lateral peroneal nerve palsy, infection, delayed unions, compartment syndrome, or pulmonary embolism.

g. Post-Operative Treatment

i. An individualized rehabilitation program based upon communication between the surgeon and the therapist and using therapies as outlined in Therapeutic Procedures, Non-operative. In all cases, communication between the physician and therapist is important to the timing of weightbearing, and exercise progressions.

ii. Weight-bearing and range-of-motion exercises depend on the type of procedure performed. Partial or full weight-bearing restrictions can range from six weeks partial weight-bearing, to three months full weight-bearing. It is usually six months before return to sports or other rigorous physical activity.

iii. If femoral intertrochanteric osteotomy has been performed, there is some evidence that electrical bone growth stimulation may improve bone density. Refer to Therapeutic Procedures, Non-operative, Bone Growth Stimulators for description.

iv. Return to work and restrictions after surgery may be made by an attending physician experienced in occupational medicine in consultation with the surgeon or by the surgeon.

9. Hardware removal. Hardware removal frequently occurs after initial MMI. Physicians should document the possible need for hardware removal and include this as treatment in their final report.

a. Description/Definition: Surgical removal of internal or external fixation device, commonly related to fracture repairs.

b. Occupational Relationship: Usually following healing of a post-traumatic injury that required fixation or reconstruction using instrumentation.

c. Specific Physical Exam Findings: Local pain to palpation, swelling, erythema.

d. Diagnostic Testing Procedures: Radiographs, tomography, CT scan, MRI.

e. Surgical Indications/Considerations: Persistent local pain, irritation around hardware.

f. Operative Procedures: Removal of hardware may be accompanied by scar release/resection, and/or manipulation. Some instrumentation may be removed in the course of standard treatment without symptoms of local irritation.

g. Post-Operative Treatment

i. An individualized rehabilitation program based upon communication between the surgeon and the therapist and using therapies as outlined in Therapeutic Procedures, Non-operative.

ii. Treatment may include therapy with or without passive therapy for progressive weight-bearing, range of motion.

iii. Return to work and restrictions after surgery may be made by an attending physician experienced in occupational medicine in consultation with the surgeon or by the surgeon.

10. Release of Contracture

a. Description/Definition: Surgical incision or lengthening of contracted tendon or peri-articular soft tissue.

b. Occupational Relationship: Usually following a post-traumatic complication.

c. Specific Physical Exam Findings: Shortened tendon or stiff joint.

d. Diagnostic Testing Procedures: Radiographs, CT scan, MRI scan.

e. Surgical Indications/Considerations: Persistent shortening or stiffness associated with pain and/or altered function.

i. Smoking may affect soft tissue healing through tissue hypoxia. Patients should be strongly encouraged to stop smoking and be provided with appropriate counseling by the physician.

f. Operative Procedures: Surgical incision or lengthening of involved soft tissue.

g. Post-operative Treatment:

i. An individualized rehabilitation program based upon communication between the surgeon and the therapist and using therapies as outlined in Therapeutic Procedures, Non-Operative.

ii. Treatments may include active therapy with or without passive therapy for stretching, range of motion exercises.

iii. Return to work and restrictions after surgery may be made by an attending physician experienced in occupational medicine in consultation with the surgeon or by the surgeon.

11. Human Bone Morphogenetic Protein (RhBMP)

a. (RhBMP) is a member of a family of proteins which are involved in the growth, remodeling, and regeneration of bone tissue. It has become available as a recombinant biomaterial with osteo-inductive potential for application in long bone fracture non-union and other situations in which the promotion of bone formation is desired. RhBMP may be used with intramedullary rod treatment for open tibial fractures an open tibial Type III A and B fracture treated with an intramedullary rod. There is some evidence that it decreases the need for further procedures when used within 14 days of the injury. It should not be used in those with allergies to the preparation, or in females with the possibility of child bearing, or those without adequate neurovascular status or those less than 18 years old. Ectopic ossification into adjacent muscle has been reported to restrict motion in periarticular fractures. Other than for tibial open fractures as described above, it should be used principally for non-union of fractures that have not healed with conventional surgical management or peri-prosthetic fractures. Due to the lack of information on the incidence of complications and overall success rate in these situations, its use requires prior authorization. Refer to Tibial Fracture.
