OUTCOMES FOLLOWING A TOTAL FEMORAL PLATING TECHNIQUE FOR MANAGEMENT OF PERIPROSTHETIC FRACTURES AROUND STABLE HIP AND KNEE IMPLANTS

Abstract

IntroductionManagement of Vancouver type B1 and C periprosthetic fractures in elderly patients requires fixation and an aim for early mobilisation but many techniques restrict weightbearing due to re-fracture risk. We present the clinical and radiographic outcomes of our technique of total femoral plating (TFP) to allow early weightbearing whilst reducing risk of re-fracture.MethodsA single-centre retrospective cohort study was performed including twenty-two patients treated with TFP for fracture around either hip or knee replacements between May 2014 and December 2017. Follow-up data was compared at 6, 12 and 24 months.Primary outcomes were functional scores (Oxford Hip or Knee score (OHS/OKS)), Quality of Life (EQ-5D) and satisfaction at final follow-up (Visual Analogue Score (VAS)). Secondary outcomes were radiographic fracture union and complications.ResultsMean OHS and OKS was 50.25, EQ-5D score was >4 for all modalities, VAS was 64.4/100. Radiographs demonstrated bony union in 58% at 3 months and 76% at 6 months. We identified no case of re-fracture however non-union occurred in 4 patients. No other operative complications were identified.ConclusionThese results suggest that TFP may be a safe, viable option for management of periprosthetic fractures around stable implants allowing the benefit of early weightbearing, satisfactory outcomes and low re-fracture risk.
