THE COMPARISON OF FIXATION AND CUT-OUT OF PROXIMAL INTRAMEDULLARY NAIL AND DYNAMIC HIP SCREW THERAPY IN THE TREATMENT OF STABLE INTERTROCHANTERIC FRACTURES OF THE FEMUR: A RETROSPECTIVE STUDY

Introduction: Intertrochanteric fractures, among the osteoporotic fractures, have higher mortality and important complications, and are more prevalent among the elderly. There are several methods for fixing these fractures that have different advantages and disadvantages. The purpose of this study was to compare the proximal intramedullary nail (PIN) and dynamic hip screw (DHS) treatments. Material and Methods: This retrospective study, investigated the cases of 300 between 2015 and 2018 patients who complained of intertrochanteric fracture were referred to Kowsar Medical Center clinic of Semnan, Iran or admitted to orthopedic section of this center have been treated either PIN or DHS method. Patients were divided into two groups of 150 and after examining the age and sex of the patients, the rate of cut-out and fixation was compared between the two groups. Results: The mean age of the patients was 640.8 years in the PIN group and 631.1 years in the DHS group, respectively. The rate of cut-out and implant fixation in this study were 2% and 98% in patients treated with PIN and 6.66% and 93.4% in patients treated with DHS, respectively. As well as in terms of gender in implant cut-out in PIN and DHS group 66.66% and 70% of them were women, 33.33% and 30% men, respectively. Conclusion: According to the results of this study, proximal intramedullary nail treatment in comparison to dynamic hip screw treatment, in the treatment of intertrochanteric fractures, has more fixation and less cut-out.
