UNLABELLED To analyze anatomical variations of the proximal end of femur that could cause a femoroacetabular impact. METHODS 199 skeletically mature anatomical specimens of femurs were used. The femurs were measured in order to determine the anteversion angle of the femoral neck, neckshaft angle, sphericity of the femoral head at anteroposterior and superoinferior, angle between epiphysis and...

Failures in the treatment of fractures of the femoral neck are caused by several factors. Some of these, such as avascular necrosis of the femoral head, cannot be avoided. Other factors, such as inaccurate reduction or imperfect fixation, can be partly controlled. The possibility has long been considered that the nail itself and the disturbance caused by its introduction might damage the blood ...

We describe a method of intertrochanteric osteotomy with posterior rotation of the femoral head and neck. We analysed 45 hips in 44 children and adolescents aged from six to 18 years with residual dysplasia after conservative (35) and operative (10) treatment of developmental dysplasia of the hip complicated by avascular necrosis of the femoral head. In ten, femoral osteotomy was combined with ...

OBJECTIVE To determine the concentrations of lead (Pb) and cadmium (Cd) in three kinds of materials (cartilage, cortical bone, and cancellous bone) of the femur head obtained from patients in the process of operation. METHODS Concentrations of Pb and Cd were determined in selected parts of the femur head of 30 patients after total hip arthroplasty, using ICP-AES (atomic absorption spectrophot...

An osseous tissue represents a specific repository of many metals. Some of them are physiologically accumulated in the skeleton, while others remain in the bones as a result of exposure and can be the cause of pathological states. The aim of this study was to determine the occurrence and co-occurrence of As with trace elements in the femur head; analyzing their concentration in male and female ...

Background. The biomechanical effect of two implants, namely, proximal femoral nail antirotation for Asia (PFNA-II) and Expert Asian Femoral Nail (A2FN), for treating subtrochanteric fracture during healing stages, is still unclear. Methods. A 3D finite element model of an intact femur was constructed and validated. The fractured and postoperative models were accordingly produced. The postopera...

Avascular necrosis (AVN) of the head of the femur is a potentially crippling disease which mainly affects young adults. Although treatment by exposure to hyperbaric oxygen (HBO) is reported as being beneficial, there has been no study of its use in treated compared with untreated patients. We selected 12 patients who suffered from Steinberg stage-I AVN of the head of the femur (four bilateral) ...

BACKGROUND AND PURPOSE The purpose of this case report is to describe the outcome of a patient following fixation of a midshaft femur fracture and an evaluation-based, immediate-weight-bearing approach to rehabilitation. CASE DESCRIPTION The patient was a 28-year-old male manual laborer whose left femur was fractured in a head-on motor vehicle accident. The patient was treated with internal f...
