Intertrochanteric hip fracture accounts for approximately one quarter of all hip fractures in the elderly. Intertrochanteric fractures are broadly classified as stable and unstable intertrochanteric fractures. An unstable intertrochanteric fracture of the hip has the potential to displace or result in nonunion despite what appears to be adequate reduction and internal fixation. In spite of a host of operative techniques and fixation devices, none of the method has gained universal acceptance for the treatment of intertrochanteric hip fractures. If the displacement is minor, it results in minimal limb shortening.If its severe, it will lead to cutout of the femoral head and may also lead in malunion, nonunion and failure of the fixation device.The sliding hip screw is the most widely used implant for stabilization of both stable and unstable intertrochanteric fractures. However, with more unstable fracture patterns, problems with compression hip screw fixation, such as excessive fracture collapse and implant cutout has been increase in trend.DHS implant is slightly modified to limit the over collapse which is undesired in unstable trochanteric fractures. We have modified the DHS device such that the fracture collapse can be limited to a maximum of about 1 cm so that over collapse and complication of over collapse can be prevented. We have used this modified implant in 23 patients and had successful outcome in 20 patients. Thus Modified DHS is an useful tool in the management of unstable intertrochanteric fracture.
