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 ...
Chondromyxoid fibroma (CMF) is the least common benign cartilaginous tumor, comprising less than 0.5 to 1% of all skeletal neoplasms. This subject was a 16-year-old female with a three-year history of pain involving the distal femoral metaphysis. This case showed an unusual feature: it was intracortical in location. Radiologic differential diagnosis included metaphyseal fibrous defect, perioste...
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...
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...
BACKGROUND Patellar instability can cause significant disability in both pediatric and adult patients, and it is associated with several factors including genu valgum. In this study, we describe the role of a lateral opening wedge distal femoral osteotomy (DFO) combined with lateral retinacular release in addressing genu valgum with associated patellar instability. The rationale for this approa...
Introduction. The main indication for knee arthrodesis in tumor surgery is a tumor that requires an extensive resection in which the joint surface cannot be preserved. We report a patient that had knee desarthrodesis 41 years after giant cell tumor resection followed by a knee arthrodesis. This is the longest reported follow-up after desarthrodesis and conversion to total knee arthroplasty (TKA...
Although cementless revision arthroplasty of the hip has become the gold standard, revision arthroplasty of the distal femur is controversial. This study evaluated the anchoring principles of different femoral revision stem designs in extended bone defect situations, taking into account the anatomical conditions of the proximal and distal femur, and the resulting primary stability. Cementless p...
