Functional Outcome of Bipolar Hemiarthroplasty for Proximal Femoral Neck Fractures in Elderly: A Prospective Study

design would decrease protrusion, dislocation, and acetabular erosion.It also maintains the stability of the joint and increases hip function.7,8 Cemented fixation has an advantage as it enhances the initial fixation strength among geriatric with poor bone quality, on the other hand, cementless fixation encourages biological fixation and can reduce cardiovascular toxicity.9 It can be said that for unstable intertrochanteric fractures in the older population bipolar hemiarthroplasty is an enduring and adaptable solution.10 Fixation loss, excessive collapse, and cut-out of the lag screw causing poor function remain an issue related to internal fixation of unstable intertrochanteric fracture in the geriatric patients having osteoporotic bones.Studies show that several surgeons recommend a prosthetic replacement for the treatment of unstable intertrochanteric fractures to enable the earlier postoperative weight-bearing as well as to prevent excessive collapse at the site IntroductIonHip fractures are the most frequently seen injuries by orthopedic surgeons and are particularly prevailing in the geriatric community.Over one-third of the adult population of age 65 and above experience a fall each year. 1 Among all types of hip fractures, intertrochanteric hip fractures make up 45% making it majorly observed hip fractures.2 In geriatric patients, displaced femoral neck fractures are considered fatal injuries.They not only decrease the quality of life but also are related to morbidity and cause an increase in the risk of death.3 In the year 1990, the incidence was estimated to be 1.66 million with a probability of increasing up to 6.26 million in 2050, because of the increasing longer duration of life of the geriatric population.4 For the treatment of these fractures, there are various options available which include hemiarthroplasty, total hip arthroplasty, and internal fixation.5 As per surveys conducted in the past, hemiarthroplasty is considered to be the most accepted treatment option by surgeons.5,6 Professionals supporting hemiarthroplasty consider that the rate of nonunion is increased with age.This higher need for early reoperation is associated with fixation making replacement a more dependable and proven choice of treatment for the geriatric population.Hemiarthroplasty causes speedy recovery of mobility and delayed issues of loosening and wear are of lower concern in patients with a short lifespan.The treatment targets for femoral neck fractures timely return to an adequate functional status along with the decline in morbidity, mortality, and the need for reoperation.6 Bipolar hemiarthroplasty has an extra inner bearing between the endoprosthetic head component and the stem.Theoretically, this
