Revision with dynamic compression plate and cancellous bone graft for aseptic nonunion after surgical treatment of humeral shaft fracture.

Background: We evaluated the effect of revision with dynamic compression plate (DCP) and cancellous bone graft for aseptic nonunion after surgical treatments of humeral shaft fracture.

Method: Eighty-six patients with aseptic nonunion of humeral shaft fracture after various surgical treatments were reviewed and analyzed retrospectively between January 1982 and August 2006. There were 59 men and 27 women with the average age of 42 years (range, 19-81 years).

Risk factors in cutout of sliding hip screw in intertrochanteric fractures: an evaluation of 937 patients.

The aim of this study was designed to assess the risk factors of lag-screw cutout in the treatment of intertrochanteric fracture with a dynamic hip screw (DHS). From 2003 to 2007, 1,150 patients who had acute unilateral intertrochanteric fractures of the femur were enrolled to the study. All fractures were managed by closed reduction and internal fixation with 135° DHS devices.
