PURPOSE To evaluate the insertion torque of a soft-tissue interference screw in relation to depth of insertion into the tibial tunnel when used for fixation of a quadrupled semitendinosus-gracilis autograft in anterior cruciate ligament reconstruction. TYPE OF STUDY Biomechanical cadaver study. METHODS Ten quadrupled semitendinosus-gracilis grafts were harvested from fresh-frozen cadaver kn...

PURPOSE Fixation of proximal femoral megaprostheses is achieved in the diaphyseal isthmus. We hypothesized that after extended bone resection including the proximal part of the isthmus a reduced length of fixation will affect the stability and fixation characteristics of these megaprostheses. The aim of this study was to analyze in a validated sawbone model with extended proximal femoral defect...

background: candida albicans (c. albicans) may have cariogenic potential but its role in caries etiology has not been established. the aim of this study was to determine c. albicans in supragingival dental plaque and infected dentine of cervical and proximal in early childhood caries (ecc). methods: this cross-sectional study was carried out on 6o children aged 2-5 years, which were divided int...

fracture of the proximal humerus associated with vascular injury has rarely been reported in children, and only two cases have been reported in the literature. in adults this combination has been reported more frequently. we present the case of a 14 year old boy with proximal humeral epiphyseal separation and axillary artery injury.

OBJECTIVES To identify physical activity that is beneficial for the maintenance of bone strength with increasing age by examining the relation between bone mineral density (BMD) and chronic endurance training in men. BMD at the proximal femur, its subregions, and the lumbar spine, and serum testosterone were compared between two groups of long distance runners with more than 20 years of trainin...

INTRODUCTION The end of medial opening oblique wedge high tibial osteotomy (HTO) points into a narrow area between the articular cartilage of the posterolateral proximal tibia and proximal tibiofibular joint (PTFJ) at the tibial site, which is an anatomical safe zone (ASZ) for osteotomy. We studied the ASZ and its relation to the fibular tip, including the level of posterior cruciate ligament (...

background: intertrochanteric fracture is one of the most common fractures of the hip especially in the elderly with osteoporotic bones, usually due to low-energy trauma like simple falls. dynamic hip screw (dhs) is still considered the gold standard for treating intertrochanteric fractures by many. not many studies compare the dhs with proximal femoral nail (pfn), in type ii intertrochanteric ...
