OBJECTIVE To compare the fixation stability in the femoral head with sliding hip screw versus helical blade designs for unstable, intertrochanteric hip fractures. METHODS A simulated, unstable intertrochanteric hip fracture was created in six pairs of cadaveric femurs. One of each pair was treated using an intramedullary nail with a sliding hip screw (ITST) for femoral head fixation and the o...

For accurate analysis of bone formation and resorption during fracture healing, correct registration of follow-up onto baseline image is required. A per-fragment approach could improve alignment compared to standard registration based on the whole fractured region. In this exploratory study, we tested the effect of fragment size and displacement on a per-fragment registration, and compared the ...

BACKGROUND Surgical intervention is increasingly performed as the primary treatment of unstable Hangman's fracture. Some authors have advocated using anterior C2/3 discectomy with interbody fusion and plating to treat unstable Hangman's fracture combined with intervertebral disc injury; however, there are few reports on unstable Hangman's fracture treated by anterior interbody fusion with the c...

INTRODUCTION Unstable intertrochanteric fractures are difficult to manage and the choice of implant is critical for fracture fixation. The purpose of this study was to evaluate the functional and radiological outcome of proximal femoral nail antirotationII (PFNA II) in the treatment of unstable intertrochanteric fractures. MATERIALS AND METHODS We reviewed 45 patients of unstable intertrochan...

OBJECTIVE We analyzed the comparative efficacy and long-term prognosis with proximal femoral nail anti-rotation (PFNA) and dynamic hip screw (DHS) for the treatment of unstable intertrochanteric fractures, retrospectively. We determined the independent risk factors to guide subsequent surgery and improve the long-term quality of life. PATIENTS AND METHODS We selected 165 patients suffering fr...
