An important factor in the internal fixation of pertrochanteric fractures is the ability to maintain postoperative reduction. Excessive postoperative sliding of the lag screw or blade may result in reduction loss. We retrospectively analyzed the relationship between postoperative reduction and sliding. From Oct. 2009 to Sept. 2011, we treated pertrochanteric fractures using J-PFNA (Synthes) and InterTAN (Smith & Nephew) in 91 cases and 82 cases, respectively. We used postoperative radiographs to classify its reduction. Fractures were classified for its interfragmentary contact using the calcar femorale as a reference on the A-P plane while using the anterior cortex as a reference on the M-L plane.Introduction
Methodology
The usefulness of arthroscopic reduction for the intra-articular fracture of the distal radius has been reported, although it is technically difficult. Our hypothesis is that the reduction using the external fixator is useful as equivalent to the arthroscopic reduction for the intra-articular fracture of the distal radius fracture in the fixation with the volar locking plate.Background
