Revision total hip arthroplasty (THA) is challenging when there is severe loss of bone in the proximal femur. The purpose of this study was to evaluate the clinical and radiographic outcomes of revision THA in patients with severe proximal femoral bone loss treated with a fluted, tapered, modular femoral component. Between January 1998 and December 2004, 92 revision THAs were performed in 92 pa...

background: floating knee, referred to as ipsilateral fractures of the femur and tibia, is usually associated with several complications and mortality. this study was designed to present our experience with treatment of this injury throughout; age, sex, mechanism of injury, associated injuries, method and results of treatment, and complications of floating knee are discussed. materials and meth...

OBJECTIVE To study the mortality and morbidity associated with proximal femoral fractures with reference to fracture type (intracapsular and extracapsular). DESIGN Consecutive prospective study with 12 month follow ups. SETTING Two British trauma receiving centres. PATIENTS 1000 consecutive acute proximal femoral fractures (fractured necks of femur) in 972 patients. RESULTS Significantl...

PURPOSE To compare pressures generated by 2 different cement pressurisers at various locations in the proximal femur. METHODS Two groups of 5 synthetic femurs were used, and 6 pressure sensors were placed in the femur at 20-mm intervals proximally to distally. Cement was filled into the femoral canal retrogradely using a cement gun with either the half-moon pressuriser or the femoral canal pr...

Recently, we experienced a case where the diagnosis and management of a deep femoral artery rupture was delayed. This vascular complication occurred during the insertion of a distal interlocking screw of a proximal femoral nail for the fixation of an intertrochanteric femur fracture. A 79-year-old male patient was diagnosed with a right intertrochanteric fracture after a fall. We fixed the frac...

Grayton, J. 40 CASE REPORT A 27 month-old, castrated, male domestic short hair cat was presented with acute onset of non-weight-bearing right pelvic limb lameness of four hours duration. The cat was kept indoors and had no history of trauma. Pain was elicited on manipulation of the right pelvic limb. At first the lameness appeared to be centered at the tarsus; radiographs of the right tarsus we...

OBJECTIVE To determine how axial rotation around the anatomic axis of the femur, as would occur with malrotation of a femoral fracture, affects frontal and sagittal plane alignment and knee joint orientation. DESIGN Computer-generated models of the lower extremity were constructed using standardized dimensions. To simulate a malrotated fracture, these models were rotated in the shaft around t...
