Longitudinal tears of peroneus longus and brevis tendons: a gouty infiltration

Abstract

The natural history of recurrent uric acid deposition includes joint destruction, as well as tendon weakening and rupture. Simultaneous rupture of the peroneus longus and brevis tendons secondary to tophaceous gout is very rare. In the present report, we describe the case of a 37-year-old man who had a history of recurrent ankle pain and 4 previous episodes of acute gout localized to his ipsilateral first metatarsophalangeal joint. The physical examination revealed the ankle pain to actually be localized to the peroneal tendons immediately distal to the fibular malleolar groove. Magnetic resonance imaging showed longitudinal tears in the peroneus longus and brevis. Surgical exploration and repair of the ruptured tendons revealed the presence of monosodium urate deposition within the substance of the tendons at the rupture sites. The tendons were debrided and repaired using longus to brevis tenodesis. The postoperative course was unremarkable and entailed referral to a rheumatologist for metabolic management. After more than a 1-year period of follow-up, the patient was ambulating without difficulties wearing regular shoe gear.
