Abstract: Objective To analyze the distribution of tophus in ankle and tarsal joints by multislice spiral computed tomography (MSCT)and to explore the pathogenesis of gout.Methods 34 patients with a documented diagnosis of gout underwent CT examina-tion of bilateral ankle and tarsal joints,and 55 ankle and tarsal joints were observed tophus.The sites of tophus deposition were cate-gorized into groups of ligament,tendon and joint in order to record and analyze.Results The tophus were showed at the anterior talofibular ligament (n=38),the medial ligament (the site of talus and calcaneus)(n=30)and the interosseous talocalcaneal liga-ment (n=29)(P <0.05)in the group of ligament;at achilles tendon (n= 18),followed by tibialis posterior tendon (n= 7)(P <0.05)in the group of tendon;at articulations intercuneiformes (n=1 5)and inferior tibiofibular articulation (n= 10)(P <0.05 )in the group of joint.Conclusion In ankle and tarsal joints,tophus is commonly deposited at the anterior talofibular ligament,at the achilles tendon and the articulationes intercuneiformes.
