    Abstract:
    OBJECTIVE: To evaluate the clinical results of arthroscopical subtalar arthrodesis for malunion of calcaneal fractures. METHODS: Between July 2006 and December 2008, 12 cases of malunion of calcaneal fractures were treated with arthroscopical subtalar arthrodesis, including 10 males and 2 females with an age range of 38-54 years (44.8 years on average). The location was left side in 5 cases and right side in 7 cases. The injury was caused by falling from height in 8 cases, by traffic accident in 3 cases, and other in 1 case. It was 3-7 months from injury to operation. All cases were classified as Stephens type II. The total score was 35.68 +/- 10.35 and the pain score was 8.14 +/- 1.83 before operation according to Hindfoot scores system of American Orthopaedic Foot & Ankle Society (AOFAS). RESULTS: All incisions achieved primary healing and the patients were all followed up 14-32 months (18 months on average). The X-ray films showed bony fusion after 10-14 weeks (11.5 weeks on average). The total score was 76.45 +/- 9.83 and the pain score was 1.52 +/- 1.48 after operation according to Hindfoot scores system of AOFAS, showing significant difference when compared with those before operation (P < 0.01). CONCLUSION: Arthroscopical subtalar arthrodesis can get satisfactory fusion rate with few complications for malunion of calcaneal fractures.
