Description
Summary:The aim of this study was to inform a definitive trial which could determine the clinical effectiveness of the X-Bolt Dynamic Hip Plating System compared with the sliding hip screw for patients with complex pertrochanteric fragility fractures of the femur.This was a single centre, participant blinded, randomised, standard-of-care controlled pilot trial. Patients aged 60 years and over with AO/ASIF A2 and A3 type femoral pertrochanteric fractures were eligible.The primary outcome was the EuroQoL 5 Dimension Score (EQ-5D-3L) at one year following index fixation. A total of 100 participants were recruited, and primary outcome data were available for 88 patients following losses to follow-up and withdrawals. The mean difference in EQ-5D was 0.03 (95% confidence interval -0.17, 0.120; p = 0.720.) There were no significant differences in any of the secondary outcomes measures. The recruitment and follow-up rates from this feasibility study were as predicted.A definitive trial with 90% power to find a clinically important difference in EQ-5D would require 964 participants based upon the data from this study. We plan to start recruitment to this trial in Spring 2016.A definitive trial of X-Bolt Dynamic Hip Plating System is feasible and should be conducted now in order to quantify the clinical effectiveness of this novel implant.
