Intertrochanteric fractures occur mostly in elderly patients, and the outcome may be extremely poor if there is prolonged bed-rest.
Many treatment modalities have come up in management of these unstable intertrochanteric fractures. Sliding Hip Screw Fixation is still the gold standard in treatment of stable intertrochanteric fracture. In unstable comminuted intertrochanteric fractures, there is high incidence of failure in view of excessive collapse seen with Dynamic hip screw.
In order to limit the collapse we have done a modification on Dynamic Hip Screw implant. The aim of this study is to assess fracture healing, collapse and implant failure, in unstable intertrochanteric fractures (Boyd and Griffin type-2) treated by modified DHS fixation.
Methods: 23 patients who were operated with modified DHS for unstable intertrochanteric fracture were selected using random selection and following parameters were noted from the records.
Results: Out of 23 patients in this study, 20 patient showed fracture healing (87%) with or without minimal collapse and 3 patient had non-union (13%) at the end of 5 months follow up. Ultimately all fractures united at the end of 1 year followup.
Conclusion: Modified Dynamic Hip Screw has showed improved results as compared to normal Dynamic Hip Screw in treating communited intertrochanteric fracture, which limits the collapse at fracture site.
