We have investigated the accuracy of placement of the femoral component using imageless navigation in 100 consecutive Birmingham Hip Resurfacings. Pre-operative templating determined the native neck-shaft angle and planned stem-shaft angle of the implant. The latter were verified post-operatively using digital anteroposterior unilateral radiographs of the hip. The mean neck-shaft angle determin...

UNLABELLED Early failures after hip resurfacing often are the result of technical errors in placing the femoral component. We asked whether image-free computer navigation decreased the number of outliers compared with the conventional nonnavigated technique. We retrospectively compared 51 consecutive hip resurfacings performed using image-free computer navigation with 88 consecutive hip resurfa...

  Background: Some studies have previously shown that geometry of proximal femur can affect the probability of fracture and type of fracture. It happens since the geometry of the proximal femur determines how a force is applied to its different parts. In this study, we have compared proximal femur’s geometric characteristics in femoral neck (FNF), intertrochanteric (ITF) and Subtrochanteric (ST...

The aim of this study was to assess the influence of bone mineral density and hip geometry on the fragility fracture of femoral neck and trochanteric region. There were 95 menopausal females of age ≥ 50 years with fragility fracture of hip, including 55 cases of femoral neck fracture and 40 cases of trochanteric fracture. Another 63 non-fractured females with normal bone mineral density (BMD) w...

OBJECTIVE To ascertain the geometry of the femur in the Brazilian population by means of a radiographic study and to correlate the values with regard to sex and right/left side. METHODS Five hundred anteroposterior radiographs of the pelvis of skeletally mature patients (250 of each sex) who did not present any osteoarthrosis, fractures or tumoral or infectious lesions were analyzed. The leng...

We report five cases of intertrochanteric fractures that needed open reduction after failed closed reduction techniques. In all cases the shaft fragment included the lesser trochanter, and there was a long spike on the head-neck fragment. This was evident clinically as the proximal shaft, pulled by the iliopsoas tendon, produced a swelling in front of the hip joint. Radiographically, the fractu...

Femoral shaft fractures are very common following trauma in adults and sometimes the patient may have an ipsilateral neck of femur too. Unfortunately, be missed. The challenge lies detecting properly managing fracture presence a femoral fracture. We share our experience treating 5 patients with discuss learning points regards to diagnosis treatment this condition.International Journal Human Hea...

Bone fractures occur frequently at mid-shaft femoral site during frontal and offset automotive crashes. Because these injuries are expensive, it is crucial to understand the injury mechanisms if this injury is to be prevented. The experimental investigation of femoral shaft tolerance under loading corresponding to real world accidents requires a challenging test setup that allows applying exter...

intramedullary nailing of femoral shaft fractures, first introduced by Hey Groves in 1918 and later popularised by K#{252}ntscher (1940, 1958, 1967), B#{246}hler (1951), Street (1951) and Lottes ( 1953), is in most current textbooks described as a routine surgical operation. It is regarded as the method of choice in transverse and short oblique fractures of the femoral shaft (B#{246}hler 1951 :...

A pseudoaneurysm is a collection of blood leaking from damaged arterial wall. Development the false aneurysm due to either initial injury vessel or complication internal fixation femoral fracture. Femoral artery pseudoaneurysms (FAPs) may close spontaneously if tear small enough allow for clotting and sealing. On other hand, rupture can trigger thrombosis, distal embolization compression adjace...
