We used a trochanteric slide osteotomy (TSO) in 94 consecutive revision total hip arthroplasties (90 with replacement of both the cup and stem). This technique proved to be adequate for removing the components, with few complications (two minor fractures), and for implanting acetabular allografts (18%) and reinforcement devices (23%). Trochanteric union was obtained in most patients (96%), even...

OBJECTIVE Femoral arterial cannulation is associated with a significant risk of lower limb ischemia. The aim of the study was to assess the pressure and flow in the femoral artery using a novel bidirectional femoral cannula in a sheep model of peripheral cardiopulmonary bypass. METHODS Peripheral cardiopulmonary bypass was established using a multistage venous cannula inserted into the intern...

The effects of regional hypotension on femoral resistance artery reactivity and morphology were investigated in spontaneously hypertensive rats (SHR) and control Wistar-Kyoto (WKY) rats. A partially constricting ligature (0.4 mm i.d.) was placed around the left external iliac artery at 5 weeks, which resulted in significantly reduced femoral mean arterial pressures distal to the ligature at 12 ...

The objective of this study was to validate the use of bone mineral measurements of the calcaneus bone by dual X-ray and laser (DXL) in a cross-sectional study carried out in an osteoporosis clinic. Measurements of bone mineral density (BMD) at proximal femur and spine were obtained by dual-energy photon X-ray absorptiometry (DEXA). Osteoporosis was defined by a DEXA T-score <-2.5 at the femora...

BACKGROUND Fixation of trochanteric hip fractures using the Gamma Nail has been performed since 1988 and is today well established and wide-spread. However, a number of reports have raised serious concerns about the implant's complication rate. The main focus has been the increased risk of a subsequent femoral shaft fracture and some authors have argued against its use despite other obvious adv...

background femur fracture is one of the most common fractures in children. certain parameters such as the patient’s age, the exact location of fracture, type of fracture, the mechanism of fracture, and the accompanying injuries determine which one of the many treatment techniques be used in each case. objectives we aimed to compare the results of close and open techniques in pediatric femoral s...

Background: Patellar resurfacing after routine arthroplasty remains controversial. Few studies have specifically examined the effect of patellar resurfacing on outcomes after resection of the distal part of the femur and reconstruction with a megaprosthesis. Our objective was to compare the outcomes of megaprosthesis reconstructions of the distal part of the femur with and without patellar resu...

PURPOSE To assess outcomes of antegrade interlocking nailing for supracondylar or intercondylar fractures of the distal femur. METHODS Records of 10 women and 20 men aged 20 to 70 (mean, 48.7) years who underwent antegrade interlocking nailing for distal femoral fractures were reviewed. 23 patients had closed fractures and 7 had open fractures; 6 had associated fractures of the forearm or tib...
