Five-years long term outcomes of bipolar hemiarthroplasty in femoral neck fractures
Keywords:Bipolar Hemiarthroplasty, long term follow up, Harris hip score, Likert scale.
Introduction: Bipolar hemiarthroplasty is indicated in older age groups. Its advantages in femoral neck fractures in better pain relief, which allows early rehabilitation and ambulation of older individuals, early weight bearing. We aimed to do a retrospective outcome analysis of patients operated with bipolar hemiarthroplasty for fracture neck of femur with minimum five years follow up. Material and Methods: A retrospective study was conducted to evaluate the clinical and radiological outcome in 53 patients operated with bipolar hemiarthroplasty hip for femoral neck fractures with minimum five years long term follow-up period. Functional outcomes was assessed with use of Harris Hip score, pain, range of motion, satisfaction rate and limb length discrepancy. Satisfaction rate was calculated using likert scale. Results: The mean age was 73.62 ± 6.22 (Range, 60-92 years). Stem subsidence was seen in 15 patients (28.3%). Acetabular erosion was seen in 3 (5.66%) patients. Stem loosening wass seen in 2 patients (3.76%) and protrusio acetabuli in 1 (1.88%) patients. Hip arthritis was seen in 4 (7.54%) patients. 28 patients (52.84%) complained of pain at hip. There was no case of superficial or deep infection in any of the patients. The satisfaction rate on likert scale in our study was 77.35%. Mean Harris hip score in the present study was 83.41±4.11. Conclusion: Hemiarthroplasty is an effective treatment modality that provides satisfactory pain relief for the lifetime of the majority of elderly population. Good prosthesis survivorship is seen in elderly patients with good overall satisfaction rate.
