11/49. Distal femoral replacement with allograft/prosthetic reconstruction for treatment of supracondylar fractures in patients with total knee arthroplasty.Large-segment distal femoral allografts were used in conjunction with non-linked total knee prostheses to reconstruct bone deficits following supracondylar fracture of the femur in seven patients with previous total knee arthroplasties. Three patients with multiple medical problems died of unrelated causes prior to a minimum 2 year follow-up. Indications for surgery were previously failed attempts at osteosynthesis and significant fracture comminution, osteopenia, and intercondylar extension or femoral component loosening. Specifics of the surgical technique included subperiosteal excision of the involved distal femur with retention of a soft tissue sleeve containing the collateral ligaments and reconstruction with a large-segment allograft and a stemmed, semiconstrained total knee prosthesis. Cement fixation using pressurized technique with intramedullary plugging of the tibial and femoral canal was routinely used to secure the prosthesis/allograft construct to the host bone. postoperative complications included one dislocation, which was successfully treated closed, and one popliteal artery injury, which was successfully repaired. There were no postoperative infections. Two patients, however, had some degree of persistent instability, warranting bracing at the time of last follow-up. Using the Knee Society rating system, the average knee score for these patients was 71, and the average pain score and function score were 33 and 49, respectively. Range of motion averaged 96 degrees. All of the femoral components were well fixed at last follow-up. Results of this study indicate that large-segment distal femoral allografts used in conjunction with nonlinked knee prostheses can be an acceptable method of treatment of these difficult reconstructive problems.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
12/49. Neglected femoral diaphyseal fracture.Femoral diaphyseal fractures usually result after trauma of high magnitude and because of this, can be life-threatening injuries or may result in considerable physical disability if not treated with care and caution. Nonoperative treatment of these fractures continues to be popular among the patient population in the Indian subcontinent, which in majority of cases, leads to healing in malalignment, shortening of the limb, chondromalacia patellae, and loss of knee motion. Although the majority of these fractures are being treated by operative methods today, success of the treatment depends largely on the surgeon's familiarity with the procedure or the type of fracture pattern (comminuted or segmental) particularly in a polytraumatized patient. Delayed union and nonunion of femoral-diaphyseal fractures and implant failures usually result after these procedures or the type of injury. The purpose of this study is to discuss various types of neglected femoral diaphyseal fractures and to review the literature on their treatment.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
13/49. Above-knee Ilizarov external fixation for early periprosthetic supracondylar femoral fracture--a case report.Supracondylar femoral fractures above a total knee replacement are rare injuries that may be challenging to treat. We present a 60-year-old woman who sustained a supracondylar femoral fracture 10 days following a total knee replacement. This patient had multiple risk factors. The fracture was not deemed amenable to conventional treatment. This patient underwent fixation of her femoral fracture above a total knee replacement using a two-ring above-knee Ilizarov external fixator. This allowed full mobilization of the affected limb during fracture healing. The fixator was removed at 10 weeks, at which time the fracture was solidly healed. At the most recent follow-up, 14 months from injury, she was fully weight-bearing without walking aids and had a knee range of motion of 0-120 degrees .- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
14/49. Femoral avulsion fracture of the posterior cruciate ligament in association with a rupture of the popliteal artery in a 9-year-old boy: a case report.Ruptures of the posterior cruciate ligament (PCL) and especially proximal bony avulsion fractures in children are very rare. This in combination with a rupture of the popliteal artery is extremely rare. Thus, an exact incidence is not available from the literature. overall, these injuries are severe and often lead to chronic knee instability. We report a case of a 9-year-old boy who suffered a traumatic displacement of the left knee with a rupture of the popliteal artery. Prior to transfer to our department, he was treated by a saphenous vein bypass graft and by a transfixation of the knee using two oblique percutaneous pins. We performed magnetic resonance imaging (MRI) scan of the knee which revealed a femoral avulsion fracture of the PCL. Other ligaments and menisci were intact. A transosseous femoral fixation using non-absorbable stitches was carried out. A 1-year follow-up after surgery demonstrates intact peripheral perfusion and sensation, straight axes of both legs and a physiological gait. Minimal differences of the length and circumference of both legs could be measured. The posterior laxity (Lachman-test) was about 5/8 mm (right/left knee) and 2/5 mm (right/left knee) in 90 degrees flexion. The range of motion (extension/flexion) was 5/0/140 degrees -/5/100 degrees (right-left knee). Intact cruciate ligaments were confirmed by MRI. Minimal experience exists in treatment of combined injuries to the PCL and the popliteal artery in children.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
15/49. Differential diagnosis of a femoral neck/head stress fracture.STUDY DESIGN: Resident's case problem. BACKGROUND: Identifying stress fractures of the hip can be a challenging differential diagnosis. pain presentation is not always predictable and radiographs may not show the fracture, especially during its early stages. Hip stress fractures left untreated can displace and necessitate open reduction internal fixation or total hip arthroplasty. diagnosis: A 70-year-old woman presented to the physical therapy clinic with complaints of right hip pain. She had been evaluated by a physician and radiographs of the hip, which revealed some arthritic changes, were otherwise normal. Upon examination, the physical therapist observed an antalgic gait, a noncapsular pattern of limitation of hip motion, an empty painful end feel at the end range of motion (ROM) for hip abduction, external rotation, and flexion, and extreme tenderness to palpation over the anterior hip region. The therapist suspected a more pernicious problem than osteoarthritis and discussed his suspicion with the physician. The physician subsequently requested an MRI that revealed a femoral neck and head stress fracture that was later confirmed with a bone scan. The patient was provided with a walker for ambulation with a non-weight-bearing status for 6 weeks, after which she returned to physical therapy for progressive weight bearing and strengthening. She was discharged with a relatively pain-free hip and was ambulating with a cane. A 2-month follow-up examination revealed a pain-free hip and a return to all premorbid activities, including ambulation without an assistive device. DISCUSSION: The presence of a normal radiograph of the hip should not be considered conclusive in ruling out a stress fracture in the hip region. The current case demonstrates how careful evaluation can reveal occult pathologies and prevent potentially catastrophic morbidity.- - - - - - - - - - ranking = 2keywords = motion (Clic here for more details about this article) |
16/49. Early rehabilitation following surgical fixation of a femoral shaft fracture.BACKGROUND AND PURPOSE: The purpose of this case report is to describe the outcome of a patient following fixation of a midshaft femur fracture and an evaluation-based, immediate-weight-bearing approach to rehabilitation. CASE DESCRIPTION: The patient was a 28-year-old male manual laborer whose left femur was fractured in a head-on motor vehicle accident. The patient was treated with internal fixation of the left femur by use of an antegrade intramedullary nail. Following surgery, impairments in range of motion, knee extensor and hip abductor strength, and gait were observed. Intervention focused on immediate weight bearing and early progression of strengthening to address the observed impairments. OUTCOMES: All of the patient's impairments improved, and he was able to return to work as a manual laborer within 6 months. DISCUSSION: Immediate weight bearing with early strengthening activities following surgical correction of a midshaft femur fracture may result in early resolution of impairments and functional limitations and decreased disability.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
17/49. Massive bone allografts for traumatic skeletal defects.Large bone allograft transplants have been successfully used to reconstruct skeletal defects created by tumor resections and failed arthroplasties, but little has been reported on their use in traumatic defects. Of approximately 500 allograft procedures done at the massachusetts General Hospital from 1979 to 1988, 11 were done for restoration of traumatic bone loss. The average age of the patients was 30 (range 11 to 71 years), and the location of the defect was the tibia or femur in 10 of the 11 patients studied. Eight osteoarticular grafts (six hemicondylar and two total condylar) and three intercalary grafts were used for six open and five closed fractures. The time from injury to reconstruction averaged 17 months (3 to 96 months). Primary reconstruction was done in three cases and a salvage procedure in eight. patients were assessed by the operating surgeon and a physical therapist using an evaluation system that considers function, life-style, and emotional acceptance. According to the system, nine patients had excellent or good results (six hemicondylar grafts, three intercalary grafts), one patient had a fair result (total elbow graft), and one patient had failure of a total condylar graft and subsequently required an amputation. This study suggests that large bone allografts are of value in reconstructing traumatic skeletal defects, especially those involving an articular surface in a young patient.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
18/49. Heterotopic ossification in central nervous system-injured patients following closed nailing of femoral fractures.Heterotopic ossification at the site of insertion of an intramedullary nail was observed in five central nervous system-injured patients with femoral fractures. Three of these patients experienced a reduction in the range of motion of the ipsilateral hip joint, which in two improved with physical therapy. patients with central nervous system injury who have closed interlocking intramedullary nail fixation may be at increased risk of heterotopic ossification at the surgical site.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
19/49. periprosthetic fractures in patients with total knee arthroplasties.Ten patients with total knee arthroplasties sustained periprosthetic fractures. Nine of these were supracondylar fractures, and one occurred in the middle one-third of the tibia. These patients were treated with conservative methods in two cases and internal fixation with plate and screws in three cases. The remaining five patients were treated with intramedullary fixation using a specially designed revision prosthesis with long intramedullary stems. The best results wer achieved through the revision arthroplasty, based on walking ability, range of motion, and early rehabilitation.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
20/49. femoral fractures secondary to low velocity missiles: treatment with delayed intramedullary fixation.The literature is replete with descriptions of the advantages of intramedullary nailing in the treatment of femoral fractures. However, little has been reported about the use of this method in femoral fractures resulting from gunshot wounds. Often, the amount of bony comminution and retained metal fragments have discouraged attempts at operative intervention. We reviewed our experience with 26 patients who had sustained low velocity gunshot fractures of the femur that were treated operatively with intramedullary fixation. After injury, the patients were stabilized in the emergency room and placed in balanced skeletal traction. They also received local wound care. When the patients recovered from associated injuries and the bullet wounds were healing, a delayed closed intramedullary nailing was performed. Nineteen patients were followed to union. Seventeen had fractures that united at an average of 4.5 months. One patient had a delayed union, and one had a nonunion. There were no deep wound infections and no cases of osteomyelitis. Range of motion was within 10 degree of the unaffected side in all but one patient, and there were neither rotatory nor angular deformities.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
