FUNCTIONAL OUTCOME OF BIPOLAR HEMIARTHROPLASTY IN DISPLACED INTRACAPSULAR FEMORAL NECK FRACTURE IN ELDERLY IN RURAL TERTIARY HOSPITAL

Abstract

Femoral neck fractures, one of the most common injuries in the elderly have always presented great challenges to orthopaedic surgeons. The present study was conducted in 42 elderly patients with closed displaced intracapsular fracture of femoral neck following all inclusion and exclusion criteria who were present to the Orthopaedics department from October 2019-May 2021 to evaluate functional outcome of bipolar hemiarthroplasty in displaced intracapsular femoral neck fracture in elderly who were followed for duration of 6 months at an interval of 6 weeks, 3 months and 6 months. Most of the patients were belonging to 65-69 years of age group accounting to 33.33%. Females outnumbered males accounting to 59.52% with female to male ratio of 1.47:1. Transcervical fractures outnumbered and accounted for 90.48%. There were more left sided fractures accounting for 71.43%. Most of the patients were operated within 7 days of fracture accounting for 45.24% with average hospital stay of 14.71±4.79 days. Most common mode of injury was trivial trauma i.e.92.86%. 41mm Bipolar prosthesis size accounted for maximum of 28.6%. Harris Hip Score was used to evaluate the functional outcome of Bipolar Hemiarthroplasty was noted at regular follow ups.  Mean Harris Hip score at 6 weeks was 74.21±10.07, at 3 months was 77.66±10.59, at 6 months was 80.40±10.60 with upward trend in the mean score over follow up period. There was 2.38% cases of posterior dislocation noted at 1 month in Uncemented Bipolar Hemiathroplasty postoperatively, 4.76% cases of infection and 7.14% cases of lengthening, 7.14% cases of Bedsores. The final functional outcome at 6 months of follow up revealed excellent results in 13 patients(30.95%), Good in 11 patients(26.19), Fair in 12 patients(28.57%) and Poor results in 6 patients(14.29%). Our study concludes that Bipolar Hemiarthroplasty offers excellent, painless mobility and ease in rehabilitation and return to function.
