Changhai Hospital Affiliated to the Second Military Medical University Shanghai China Abstract Objective To evaluate the effectiveness of the treatment of tophi resection + mini locking plate metatarsophalangeal MTP joints arthrodesis for the tophi arthritis. Methods The clinical data of 21 patients 32 feet undertaking tophi resection + mini locking plate arthrodesis in our hospital between May 2010 and March 2013 were retrospectively analyzed. Results At the last follow - up the mean VAS score of the postoperative feet was 2. 4 ± 0. 6 the mean AOFAS score was ± 2. 4 and the mean Tegner activity score was 4. 3 ± 0. 9 the difference was statistically significant compared with preoperative data. The wounds healed by first intention expect 1 foot with skin flap necrosis another with a tophi recurrence. Conclusion First MTP joint is mostvulnerable to tophi arthritis the function and appearance of the forefoot are usually seriously affected. Monosodium urate crystal deposition can cause joint degeneration and progressive corrosion so prompt surgical intervention is advised. Removal of the tophi and deposition and arthrodesis of the MTP joints with mini locking plate can achieve ideal outcomes preventing further bone erosion while providing rigid fixation. Additional attention should be paid to local flap protection and postoperative functional exercise is proposed.
