PurposeManaging displaced intra-articular calcaneal fractures remains controversial. A prospective randomised trial was undertaken to compare open reduction and internal fixation (ORIF) with minimally invasive reduction and percutaneous fixation (MIRPF).MethodsForty-five displaced intra-articular calcaneal fractures were randomised to undergo either ORIF (n = 23) or MIRPF (n = 22). Patients were followed up clinically and radiologically for a minimum of one year postoperatively. The primary outcome measure was wound-healing complication. Functional outcome was assessed using Creighton Nebraska Health Foundation (CNF) scale, and radiological outcome was assessed using plain radiographs and computed tomography (CT) scans.ResultsOf the 23 heels in the ORIF group, seven (30%) had wound-healing problems, compared with none in the MIRPF group (p = 0.005). There was no statistically significant difference in radiological outcomes between groups, as measured by Böhler's angle, Gissane's angle and Score Analysis of Verona (SAVE). Median time to return to work was two weeks earlier (p = 0.004), and the functional outcome score (CNF scale) at one year of follow-up was better (p = 0.013) following MIRPF compared with ORIF.ConclusionMIRPF is associated with fewer wound-healing problems, better functional outcome and earlier return to work compared with ORIF.
