A dynamic hip screw is a pin and plate fixed to the thigh bone. These are hip fractures that occur between the greater and lesser trochanter of the femur. Discuss difference between the two devices: - PFNA load sharing allowing early weight bearing - DHS load bearing, which usually does permit early weight bearing in an unstable fracture Dynamic hip screw (DHS) fixation is considered standard treatment for most intertrochanteric fractures. Dynamic hip screws are used for internal fixation of fractures of the femoral neck and intertrochanteric region. The plate is secured with screws. Looks like you’ve clipped this slide to already. While most of the modifications of implant have been done in screw design, this study evaluates the role of employing locking side plate with DHS to increase the screw hold and avoid plate pull out in trochanteric fractures of elderly patients. Introduction. The dynamic hip screw (DHS) offered by us has been designed for providing strong and stable internal fixation for various applications in intertrochanteric, subtrochanteric and basilar neck fractures, while causing minimal soft tissue irritation. The Dynamic Hip Screw is designed to provide strong and stable internal fixation of a variety of intertrochanteric, subtrochanteric and basilar neck fractures, with minimal soft tissue irritation. 1–4 As it provides rigid fixation, early mobilization is possible.
