Functional outcome of subtrochanteric femur fracture treated with proximal femoral nailing

Abstract

Context :Subtrochanteric fractures are femoral fractures where the fractures occur below the lesser trochanter to 5 cm distally in the shaft of femur. Aims :The objective of this retrospective study was to assess and document the clinical and functional outcome of subtrochanteric fractures treated with long proximal femoral nailing.Setting And Design This retrospective study conducted by department of Orthopaedics from January 2012 and July 2016 with minimum 12 months follow up period at R L Jalappa Hospital attached to Sri Devaraj Urs Medical College, Tamaka, Kolar, Karnataka.Materials and methods Sixty two patients were included in this study. Patient demographics, type of fracture according to Seinsheimer classification, type of nail used, operative details, complications were recorded. Patients were evaluated using Harris hip score for their clinical and functional outcomes.Statistical analysis used: The significance of difference in means between the groups were done by Student- t test and difference of proportions /associations by using Chi square test. P value <0.05 was considered as statistically significant. Results :Our study was on 62 patients of which 22 (32.3%) were female and 40 (67.7%) were males. Subtrochanteric fracture types 3A2.1, 3A2.2 and 3A2.3 in 14 (22.6), 34 (54.8%) and 14 (22.6%) patients respectively. Functional outcomes were good in 36 (58.1%) and bad in 26 (41.9%) patients respectively. Conclusion :The patients in our study had better functional and clinical outcomes with long proximal femoral nail fixation for sub trochanteric fractures with minimal complications.
