![]() Sliding compression hip screws have been directly compared with intramedullary fixation in many studies. Several companies have established versions of this device. A longer, full-length version of the nail was also developed. 8,9 The device was redesigned in 1997 with a smaller lateral bend, a shorter overall length, and only one distal interlocking screw. 7 Early reports suggested some substantial advantages in association with this type of fixation, including a minimally invasive surgical technique, shortened operating times, decreased blood loss, improved biomechanics, greater stability of fixation, earlier patient mobilization, and shorter lengths of stay. 6Īntegrade intramedullary nailing of intertrochanteric fractures incorporating a short nail with a large screw inserted into the femoral neck and head for interlocking was introduced by Halder in the 1980s in the form of the cephalomedullary nail. ![]() 5 The sliding lag screw can be used in combination with an intramedullary nail i.e “cephalomedullary nail” or an extramedullary side plate i.e. 4 For stable intertrochanteric hip fractures (AO classification A1.1, A1.2, A1.3) a fixed angle device in combination with a dynamic sliding lag screw is the favored treatment. 1–3 Intertrochanteric hip fractures account for approximately one half of all hip fractures. It is estimated that the number of hip fractures worldwide will increase from 1.26 million in 1990 to 2.6 million in 2025 and 4.5 million in 2050.
