Cannulated screw fixation is a minimal invasive technique to treat undisplaced femoral neck fractures. It is the preferred method in elderly patients who often suffer co-morbidities. There is scarce literature on subtrochanteric femoral fracture as a complication of cannulated screw fixation of a femoral neck fracture. This complication occurred, without an adequate trauma, in two of 35 patient...

A number of reports regarding atypical fractures of the femur have raised questions concerning the possible correlation between long-term bisphosphonate treatment and the occurrence of insufficiency fractures in the proximal femur. However, clinically, it is often confused whether is it a fatigue fracture because of implant induced stress concentration or a bisphosphonate-related atypical fract...

BACKGROUND It is controversial whether an early reduction and internal fixation can reduce the occurrence of femoral neck fracture-induced osteonecrosis of the femoral head (ONFH). This prospective study was designed to reflect the relationship between injury-to-surgery interval (ISI) and traumatic ONFH based on a canine model of femoral neck fractures. MATERIAL/METHODS Twenty-four dogs were ...

When using parallel screws for treatment of femoral neck fractures, shortening of the femoral neck might occur. Given the high revision surgery rates associated with parallel screws, we developed a questionnaire to explore (1) surgeons’ viewpoints on difficulties in the fixation of femoral neck fractures, (2) their perception of the clinical importance of femoral neck shortening after internal ...

Previous studies have suggested that femoral component positioning in resurfacing arthroplasty may affect strains in the femoral neck that could lead to decreased implant longevity, A strain gaged, Sawbones model was used to determine the femoral neck strains for a variety of resurfacing head translations and angulations. We found that head positions affected strain distributions, most position...

Bilateral femoral neck stress fracture is rarely seen. Two radiologic types of fracture, the transverse and compression, have been described. This differentiation bears importance in choice treatment. In this report, we presented a case bilateral with short review contemporary literature.
