Outcome of Vancouver type B2 periprosthetic fracture in hemiarthroplasty by trochanter hook plate

Abstract

Background: Fractures around hip is an increasing burden in elderly causing significant morbidity and mortality. Periprosthetic fractures occurring after hemiarthroplasty of hip is a serious complication. In this study, we have reviewed our experience in the treatment of periprosthetic fractures. Method: In our study 8 patients (6 men and 2 women; mean age: 65 ± 8 years) with periprosthetic fractures treated with ORIF with trochanteric hook plate with proximal unicortical screws in the zone of prosthesis and below by bicortical screws with a minimum follow up of 4months and maximum up to 1year was carried out. The average union period was checked after operation with radiologic findings. Radiologic outcomes were evaluated .All cases were assessed postoperatively for functional outcome in terms of range of motion, pain and walking distance. Results: The average time for union was 16 weeks and we have achieved 90% of union and Good range of motion with no pain. There was no case with loss of fixation or loss of reduction requiring revision surgery. Conclusion:We observed good functional outcome in patient treated with Trochanteric hook plate. Reversed trochanteric hook plate is a reliable, effective option for management of Vancouver type B2 periprosthetic femoral fractures.
