Intertrochanteric fractures: comparison between two different locking nails.

Purpose: The aim of this study was to compare two intramedullary devices used in the treatment of intertrochanteric fractures.

Method: During the period 2006-2007 46 TGN and 51 PFNA were used for the treatment of intertrochanteric fractures in our hospital. Clinical and radiological follow-up were available.

Reliability of cup position in navigated THA in the lateral decubitus position using the 'flip technique'.

Malpositioning of the acetabular component in total hip arthroplasty (THA) increases the risk of dislocation, reduces the range of motion and may contribute to bearing surface wear. During computer assisted navigation, the anterior pelvic plane is registered intraoperatively by percutaneous palpation, but this may be unreliable. The aim of our study was to evaluate the reliability of imageless navigation in acetabular positioning employing data acquisition in the supine position and surgery in the lateral position ('flip technique').
