1/635. Femoral fracture at the proximal end of an intramedullary supracondylar nail: a case report.

    Retrograde intramedullary supracondylar nails have been added to the orthopedic armamentarium for treatment of distal femoral fractures. Major complications of this new technique have not been noted. We report a case of a femoral fracture at the proximal end of a retrograde intramedullary supracondylar nail. We hypothesize that this complication may be due to the proximal end of the nail acting as a stress riser, with the cortical holes drilled for the interlocking screws compounding this effect.

2/635. sciatic nerve injury associated with fracture of the femoral shaft.

    The sciatic nerve escapes injury in most fractures of the femoral shaft. We report a case of sciatic nerve palsy associated with a fracture at the distal shaft of the femur. The common peroneal division of the sciatic nerve was lacerated by a bone fragment at the fracture site. Despite the delay in treatment, a satisfactory result was obtained.

3/635. Transient peroneal nerve palsies from injuries placed in traction splints.

    Two patients thought to have distal femur fractures presented to the emergency department (ED) of a level 1 trauma center with traction splints applied to their lower extremities. Both patients had varying degrees of peroneal nerve palsies. Neither patient sustained a fracture, but both had a lateral collateral ligament injury and one an associated anterior cruciate ligament tear. One patient had a sensory and motor block, while the other had loss of sensation on the dorsum of his foot. After removal of the traction splint both regained peroneal nerve function within 6 hours. Although assessment of ligamentous knee injuries are not a priority in the trauma setting, clinicians should be aware of this possible complication in a patient with a lateral soft tissue injury to the knee who is placed in a traction splint that is not indicated for immobilization of this type of injury.

4/635. Primary resection total knee arthroplasty for complicated fracture of the distal femur with an arthritic knee joint.

    Treatment of fractures of the distal end of the femur in an elderly patient is difficult. If the knee joint is arthritic, the problem is even greater. The reports of two patients with rheumatoid arthritis who sustained fractures of the distal end of the femur and underwent unconventional treatment with a resection total knee arthroplasty are presented.

5/635. Management of supracondylar fractures of the femur with the GSH intramedullary nail: preliminary report.

    The GSH supracondylar nail is a closed section rigid intramedullary device that combines the biomechanical advantages of intramedullary fixation with the stability of rigid internal fixation for the management of supracondylar fractures of the femur. The use of this implant is indicated in the management of distal comminuted nonarticular fractures and fractures with intraarticular extension. Intramedullary fixation provides improved fracture stabilization in both elderly patients with osteoporotic metaphyseal bone and in younger patients with extensively comminuted fractures. The experience with the GSH supracondylar nail has shown that it provides better results than supracondylar plating for the stabilization of acute fractures or revision of failed internal fixation.

6/635. Unusual longitudinal stress fractures of the femoral diaphysis: report of five cases.

    We present five cases of a distinctive type of longitudinal stress fracture of the upper femoral shaft in which the fracture line is parallel to the outer surface of the bone, in contrast to the perpendicular orientation to the cortical surface in previously reported cases of diaphyseal stress fractures. In two cases the fracture recurred after 15 and 18 months, respectively.

7/635. Ewing's sarcoma recurrence vs radiation necrosis in dynamic contrast-enhanced MR imaging: a case report.

    PURPOSE: We report a case of Ewing's sarcoma in the right distal femur in a 6-year-old male to demonstrate how dynamic contrast-enhanced magnetic resonance imaging (DEMRI) findings predicted histopathology. MATERIALS AND methods: DEMRI was performed at presentation and during and after completion of chemotherapy and radiation therapy. Histopathologic studies were done at presentation, at 77 weeks (20 weeks after a pathological fracture), and from the en bloc resection at 104 weeks. RESULTS: DEMRI predicted the early tumor response, absence of tumor recurrence, presence of necrosis and lack of fracture healing, confirmed by histopathology. CONCLUSION: DEMRI is a clinically useful tool in managing Ewing's sarcoma.

8/635. Severe anorexia nervosa associated with osteoporotic-linked femural neck fracture and pulmonary tuberculosis: a case report.

    We report a case study of a 38-year-old woman who had been suffering from anorexia nervosa (AN) since the age of 26. Before admittance to our clinic, she weighed 23.8 kg (at a height of 164 cm, 8.8 body mass index [BMI]) but still carried out strenuous physical activities. After good psychotherapeutic response and weight gain (34.4 kg), she accidentally fell and broke her femoral neck-favored as it was by osteoporosis. The X-ray taken before dynamic hip screw implantation coincidentally showed signs of pulmonary tuberculosis (TB), which could then be proven by computed tomography (CT) scans and cultures from a bronchoscopy. Other than lack of appetite and loss of weight, which we attributed to AN, there were no other clinical or biochemical indicators which could have pointed to an earlier TB diagnosis. As a result, the need for screening procedures is discussed. The manifestation of TB during the first weight gain after 12 years of severe malnutrition, during which there were no serious infections, seems to endorse former observations that AN patients appear to be "resistant" to some extent against infectious diseases, a "protection" which may be lost with convalescence and weight gain.

9/635. femur osteomyelitis due to a mixed fungal infection in a previously healthy man.

    We describe a previously healthy, 22-year-old man who, after a closed fracture of the femur and subsequent operation, developed chronic osteomyelitis. Within a few days, infected bone fragments, bone, and wound drainage repeatedly yielded three different filamentous fungi: aspergillus fumigatus, aspergillus flavus, and Chalara ellisii. Histologic examination of the bone revealed septate hyphae. After sequential necrotomies of the femur and irrigation-suction drainage with added antimycotic therapy, the infection ceased and the fracture healed. This case is unique in that it is the only known instance in which a long bone was affected in an immunocompetent individual, with no evidence of any systemic infection, by a mixed population of two different Aspergillus spp. and the rare filamentous fungus C. ellisii. Environmental factors that could potentiate the infection include blood and edema fluid resulting from the surgical procedure and the presence of the osteosynthetic plate.

10/635. Histopathology of a well-functioning hydroxyapatite-coated femoral prosthesis after 52 months.

    A fully hydroxyapatite-coated femoral implant was retrieved during autopsy. This component, provided with a bipolar femoral head, had been inserted for a displaced fracture of the femoral neck 52 months before. osseointegration of the implant was evident, without any formation of fibrous tissue :39.9% of the perimeter of the prosthesis at the level of its proximal third was interfaced with bone (62.8% at the mid-third and 65.2% at the distal third). Remodeling of bone had ensued. Deposition of bone was most prominent in the calcar zone, along the medial and lateral aspects and around the tip. Proximally, cortical porosity was found to be increased by 73%, whereas medullary bone porosity was increased by a factor of 2. Cell-mediated resorption of the coating was systematically present in these bone remodeling areas. The average thickness of the coating was respectively 10.8, 50.2 and 151.2 microns in the proximal, mid- and distal thirds of the implant. Formation of new bone was often coupled with resorption. No debris from the coating was found in the joint tissues or in the articulating surface of the polyethylene insert. These overall histopathological features support mechanical stability of the implant and active remodelling of bone along with focal removal of HA coating associated with osteoclastic activity. No side effects from coating degradation could be demonstrated.
