Purpose: Accepted landmarks for determining femoral component rotation in total knee arthroplasty (TKA) include the posterior condyles, Whiteside’s line, arbitrary three to four degrees of external rotation, and transepicondylar axis (TEA). All methods require anatomical identification, which may be variable. The purpose of this study was to radiologically evaluate femoral component rotation (C...

Surface hip replacement more commonly known as hip resurfacing arthroplasty is a type of a hip replacement that is different to a total hip replacement. In a total hip replacement femoral head and neck are removed and a metal stem is inserted to the femoral shaft. In hip resurfacing articular surface is shaved and a metal cap (Fig 1) is inserted preserving most of the bone in femoral head and n...

In revision hip arthroplasty, implant retrieval and residual bone cement removal may be major problems. Complete removal of the bone cement is key for the stable anchorage of the revision stem. As proximal access does not always provide an optimal view, fractures or inadvertent perforations of the cortical bone with the chisel or drill are frequently reported complications.1-3 Windowing of the ...

BACKGROUND The management of femoral shaft fractures using intramedullary nailing is a popular method. The purpose of this study was to evaluate the long-term functional outcome after antegrade or retrograde intramedullary nailing of traumatic femoral shaft fractures. We further determined predictors of these functional outcome scores. METHODS In a retrospective study, patients with a femoral...

BACKGROUND Treatment options for nonunion of the femoral shaft fracture after intramedullary nail fixation are controversial. The methods of exchanging an existing nail with a larger-sized nail, dynamization, removal of the nail followed by plating, and bone grafting have all been reported. From those options, exchange nailing seems to be the most popular choice. In our study, we used plate aug...

BACKGROUND To evaluate internal fixation by intramedullary Kirschner wires as a surgical technique in the treatment of femoral shaft fractures in children by a prospective study. METHODS 17 femoral shaft fractures at various levels in 16 children aged 2-15 years were treated by closed intramedullary Kirschner wiring under image intensifier control between May 2000 and October 2003. No externa...

Aim of the present study was to compare the outcomes between exchanging reamed nailing (ERN) and augmentative compression plating (ACP) in treatment of femoral shaft nonunion after intra-medullary nailing (IMN) retrospectively. A retrospective, multicentre study was performed with 188 patients (190 cases)with femoral shaft nonunion after IMN, who received therapy with either ERN (n = 92) for 44...

Proximal femoral dysplasia (proximal femoral focal deficiency) in early infancy is characterised by considerable shortening in association with a stable hip which is freely mobile from a position of some fixed flexion and lateral rotation (Fig. I). The radiograph confirms that the femur is short, and the proximal third of the femoral shaft, trochanteric area, neck and head are seemingly absent ...

BACKGROUND Research into the optimal treatment of fibrous dysplasia has been limited by the lack of an established classification system for the disease. The purposes of this study were to develop a radiographic classification for fibrous dysplasia of the proximal femur and to test this classification's intra- and interobserver reliability as well as the effectiveness of our treatments. METHO...

OBJECTIVE Increasing evidence suggests long-term alendronate use may overly suppress bone metabolism, limiting repair of microdamage and creating risk for insufficiency fractures. The purpose of this study is to demonstrate an association between alendronate use and a specific pattern of low-energy femoral shaft fracture. DESIGN, SETTING, AND PATIENTS A retrospective review was performed of p...
