Objective  To evaluate the effectiveness of Ilizarov external fixation and ankle arthrodesis in the treatment of late traumatic ankle arthritis. Methods  Between June 2013 and June 2015, 27 patients with late traumatic ankle arthritis were treated with Ilizarov external fixation technique. There were 16 males and 11 females with an age of 27-69 years (mean, 45.7 years). Sixteen cases were on the left side, 11 on the right side. All the patients suffered from traumatic ankle fractures or ligament damages caused by initial traumas. After 6 months of standard conservative treatment, the results was invalid and all patients had ankle joint pain and movement disorders. The disease duration was 3-39 years (mean, 11.5 years). According to Takakura ankle arthritis staging, there were 16 cases in stage 3 and 11 cases in stage 4. The tibial-talar angle before operation was (102.55±4.02) ° measured on conventional double-feet loading anteroposterior and lateral X-ray films. The American Orthopaedic Foot and Ankle Society (AOFAS) ankle and foot joint score was 45.72±6.45, and the visual analogue scale (VAS) score was 8.61±1.96. Results  All the patients were followed up 15-42 months (mean, 28.1 months). All ankles achieved bony fusion, the clinical healing time was 12.9 weeks on average (range, 11-18 weeks). No persistent bleeding in the incisions and needle tract occurred during the follow-up. There were 4 cases of mild needle infection, 2 cases of anterior dislocation of talus, and 3 cases with different degree of limited activity. No traumatic bone defect, bone disconnection, and false joint formation was observed. At 12 months after operation, the AOFAS ankle and foot joint score, VAS score, and tibial-talar angle were 80.53±9.14, 2.77±0.82, and (94.36±2.48)°, respectively, which were significantly improved when compared with preoperative ones (t=16.17, P=0.00; t=14.28, P=0.00; t=9.01, P=0.00). The effectivenss was excellent in 9 cases, good in 13 cases, and fair in 5 cases, with an excellent and good rate of 81.5%. Conclusion  Satisfactory effectiveness can be obtained through Ilizarov external fixation and ankle arthrodesis in the treatment of traumatic ankle arthritis, showing certain application prospect, while long-term effectiveness should be comfirmed by large sample randomized controlled trials.
