Role of Bipolar hemiarthroplasty in geriatric patients with hip implant in failure

Abstract

: The incidence of different hip implants failing in situ, irrespective of the cause, is on the rise. On the other side, its management remains widely understudied. Bipolar hemi-arthroplasty contributes to the salvage of failed trochanteric fracture fixation. Managing such cases necessitates skills related to complex trauma and advanced arthroplasty. It is crucial for the surgeon to comprehend and individualize surgical modalities based on the patient, fracture, and implant.This case series presents three different cases involving three distinct implants undergoing failure and their management through Bipolar Hemi-arthroplasty.: Three previously operated hip fracture cases with three different implants in the elderly population presented with implant in situ failure. They were surgically managed with a cemented modular bipolar prosthesis. Following this, a postoperative protocol was maintained, and the postoperative outcome was graded using the Hip scoring system. Bipolar arthroplasty enhances the long-term outcome of hemiarthroplasty due to reduced wear of the metal–cartilage interface. It stands as a viable, valid, and sound surgical modality compared to other surgical and non-surgical options.
