Abstract
OBJECTIVE: To evaluate the effectiveness of lesion clearance combined with Ilizarov technique for the treatment of tophi in first metatarsophalangeal (MTP) joint with bone defect. METHODS: Between July 2016 and June 2018, 14 cases of tophi in the first MTP joint with bone defect were treated by lesion clearance combined with Ilizarov technique. There were 12 males and 2 females. The average age was 39.3 years (range, 22-60 years). The disease duration ranged from 5 to 15 years, with an average of 11.2 years. The tophi volume ranged from 2.5 cm×2.7 cm×2.2 cm to 5.2 cm×2.9 cm×2.4 cm. The X-ray films showed that the length of the bone defect ranged from 2.0 to 4.6 cm, with an average of 3.4 cm. Preoperative visual analogue scale (VAS) score was 7.6±0.9; American Orthopaedic Foot and Ankle Society (AOFAS) score was 47.5±4.3; short-form 36 health survey scale (SF-36) score was 79.7±4.7. RESULTS: The incision primarily healed in 13 patients after operation. The skin necrosis at the edge of the incision occurred in 1 patient and recovered after symptomatic treatment. All 14 patients were followed up 12-16 months, with an average of 13.6 months. X-ray films showed that the first metatarsal column defects were repaired. The time of bone extension ranged from 2 to 6 weeks, with an average of 3.6 weeks. The time of bone healing ranged from 9 to 16 weeks, with an average of 11.2 weeks. During follow-up, no complication such as nerve, blood vessel, or tendon injury, needle tract infection, or stress fracture occurred. At last follow-up, VAS score was 1.4±0.5, AOFAS score was 86.6±4.8, and SF-36 score was 89.1±3.3, all of which were superior to preoperative scores, with significant differences ( t=22.532, P=0.000; t=22.702, P=0.000; t=6.124, P=0.000). CONCLUSION: Lesion clearance combined with Ilizarov technique is a safe and effective method for the treatment of tophi in the first MTP joint with bone defect.
