title: Prosthetic surgery in fragility osteopathy.
abstract: Elderly osteoporotic patients with a femoral neck fractures should undergo hip prosthesis replacement. Nevertheless, there is still debate about the best choice of treatment (Total Hip Replacement (THR) vs HemiArthroplasty (HA)). The aim of our study is to compare functional results of new polycarbonate- urethane (PCU) cup coupled with large diameter femoral head THR and bipolar HA. To verify our hypothesis, a consecutive series of 60 patients were randomized either to receive a bipolar HA or a THR. No statistically significant difference was found between the two groups in terms of age, surgical time and blood loss. Splitting the Harris Hip Score into two categories, pain and function, a trend for a better functional score was found in THR either at 3 and 12 months when compared to HA. Our study suggests that the use of a PCU acetabular cup with large diameter femoral head is an effective solution for osteoporotic patient and may provide a better hip function to this patient population. These positive results should be confirmed at a longer follow-up in a large cohort of patients.
