Abstract:Objective To evaluate the outcome of ankle arthrodesis using Ilizarov fixator for patients with end-stage ankle arthropathies.Methods We retrospectively studied 20 patients who underwent ankle arthrodesis with Ilizarov external fixator from May 2016 to December 2017.Twelve male patients and 8 female patients were included.The mean age was (59.05±7.83)years old(range 47~77 years).Outcomes were measured by The American orthopaedic foot and ankle society (AOFAS) hindfoot score,rate of union,rate of complications,and alignment of the ankle joint.Results Ankle fusion was achieved in allpatients.The mean time to healing was (3.70±1.04)months (range 3~6 months).Delayed wound healing,stent-tract infection and severe swelling were presented in one patient separately.Medial tibial talar angle improved from (86.84±6.26)degrees pre-operatively to (89.90±1.37) degrees post-operatively (P<0.05).Lateral talar station decreased from (5.50±3.97)mm to (2.85±2.72)mm(P<0.05).AOFAS score improved significantly from (39.00±8.34) pre-operatively to (80.65±8.86) post-operatively(P<0.001).Conclusion Ankle arthrodesis using Ilizarov fixator can achieve good radiological and clinical outcomes for patients with end-stage ankle arthropathy,associated with low prevalence of ankle joint malalignment and high fusion rates.
