Abstract: Introduction: Per trochanteric fractures are defined as fractures that start at the extra capsular region of the basilar neck and proceed through or below the greater trochanter along the lesser trochanter. Nearly 50% of all proximal femoral fractures are per trochanteric fractures. The goal is to investigate the issues associated with unstable proximal femur fractures treated using proximal femur locking compression plates (PF-LCP) and their functional and radiological outcomes.
Material and Methods: A total of 30 cases were included in our prospective study with unstable per trochanteric fractures treated with proximal femoral locking compression plate between May 2021 and May 2022. These proximal femoral fractures included unstable – intertrochanteric with sub trochanteric extension and sub trochanteric with intertrochanteric extensions. At six weeks, three months, and six months, clinical and radiological follow-ups were conducted as per the standard procedure. Standard anteroposterior and lateral X-rays of the operated hip were used to evaluate radiological outcomes such as union and neck-shaft angles. A modified Harris Hip Score was used to evaluate clinical and functional outcomes.
Results: Among the 30 cases, the mean age was 40+/-14.6 years and the most common mode of injury was road traffic accidents. They were treated with PF-LCP. The average radiological time of union was 13.7+/-1.74 weeks. The mean average of Harris Hip Score in our study was 86.4 with 11 excellent (35%), 15 good (50%), and 4 fair (15%). The neck-shaft angle for 90% of patients was between 120Ëš-135Ëš. One patient developed varus collapse which eventually failed to unite, and two patients had screw pull out.
Conclusion: There has always been debate over the best implant to employ for treating unstable per trochanteric fractures. We conclude that the use of PF-LCP is a reliable, stable option. It offers excellent to good bone healing, lesser complications, and more biomechanical stability.
