Abstract

Open reduction in an AO 33-A3 class distal femur transverse and comminuted fracture is often difficult due to frequent reduction loss during surgery, leading to longer operative time and increased blood loss intra-operation. In this study, the authors report a case in which the use of an offset grid plate (OsteoMed, USA) using 2.4 mm HPS (hand plating system) eased the process of fracture reduction and achieved a stable internal fixation, ultimately leading to successful osteosynthesis. The authors experienced no need for temporary fixation devices such as K-wires or screws, which are otherwise required to stabilize the reduction. The fracture reduction was stable throughout the primary fixation of the fracture using a locking plate and screws. The authors report that the advantage of the HPS plate is fitting into the cortical contour and providing stable maintenance of fracture reduction intra-operation, which would be beneficial in certain distal femoral fracture patterns.
