Abstract: Introduction: Pertrochanteric fractures are defined as “Fractures occurring in the region extending from the extracapsular basilar neck region to the region along the lesser trochanter proximal to the development of medullary canalâ€. Incidence of pertrochanteric fractures increase with increase in the age of population and quite often results in the end of patient’s functional independence. Management of pertrochanteric fracture depends on patient’s medical condition, quality of bone and the fracture biomechanics. The main goal of this study is to assess and compare the NSA in surgically fixed pertrochanteric fracture of femur at time of surgical fixation and compare it with final NSA attained at time of fracture union.
Material & Method: This Observational and prospective study was conducted over a period of 1 year and includes 100 cases of pertrochanteric fractures with mature skeleton. X-ray of pelvis with both hips AP view was taken after fixation of fracture using standard protocol. Measurement of NSAs in the operated hips was done using postoperative digital X - ray films with help of Bersoft image measurement software trial version 8.49. Data was analyzed for NSA in non-fractured limb and the restoration/change in NSA in operated hip after surgical fixation and in follow up period.
Result: In our study, the statistical analysis showed that mean NSA after immediate post op was 130.445 ± 11.1976, after 6 weeks was 128.586 ± 11.1954 and 127.305 ± 9.9472 at union.
Conclusion: Irrespective of fixation method used (DHS/PFN), NSA significantly changes during first 6 weeks in the post op period and after 6 weeks it remains unaffected and fracture become relatively stable. Therefore it can be concluded that there is no need to delay mobilization past 6 weeks of surgery.
