Abstract
Is there a Significant Difference in Surgery and Outcomes between Unipolar and Bipolar Hip Hemiarthroplasty? A Retrospective Study of a Single Institution in Singapore
Highlights
Femoral neck fractures are a common insufficiency fracture in the elderly
In a study of 222 patients reported by Frihagen, hip hemiarthroplasty was associated with better functional outcomes than internal fixation in the treatment of displaced fractures of the femoral neck in elderly patients 2
We present the results of a retrospective study comparing the length of hospital stay, cost of stay, operation time and operative complications between unipolar and bipolar hip hemiarthroplasty in our local geriatric population
Summary
Femoral neck fractures are a common insufficiency fracture in the elderly. Ravikumar followed 290 patients with displaced subcapital femur fractures for 13 years and reported that a higher rate of revision surgery was needed in those who underwent open reduction (as compared to those who had hemiarthroplasty or total hip arthroplasty), due to internal fixation nonunion and avascular necrosis 1. In a study of 222 patients reported by Frihagen, hip hemiarthroplasty was associated with better functional outcomes than internal fixation in the treatment of displaced fractures of the femoral neck in elderly patients 2. It seems that femoral head replacement surgery is preferred in the elderly. There is little data available comparing both unipolar and bipolar hip hemiarthroplasties and the costs associated with osteoporotic hip fractures in Singapore. We present the results of a retrospective study comparing the length of hospital stay, cost of stay, operation time and operative complications between unipolar and bipolar hip hemiarthroplasty in our local geriatric population
