RT Journal Article SR Electronic T1 Split Peroneus Brevis Tendon: An Unusual Cause of Ankle Pain and Instability JF The Journal of the American Board of Family Medicine JO J Am Board Fam Med FD American Board of Family Medicine SP 297 OP 302 DO 10.3122/jabfm.2014.02.130009 VO 27 IS 2 A1 Bindiya Chauhan A1 Pina Panchal A1 Edward Szabo A1 Thad Wilkins YR 2014 UL http://www.jabfm.org/content/27/2/297.abstract AB Tears of the peroneus brevis tendon may cause ankle pain, swelling, and instability. Supportive therapy with ankle bracing and analgesics is the mainstay of therapy, but surgical repair is often required in patients with ongoing symptoms. Surgical options include debridement, tubularization, or, in severe cases, resection of the damaged tendon and tenodesis. We describe a 64-year-old woman with a split peroneus brevis tendon presenting with lateral ankle pain, swelling, and instability, and we review the literature regarding presentation, diagnostic testing, pathophysiology, predisposing factors, and treatment recommendations. Primary care physicians should consider peroneal tendon injuries in patients with chronic lateral ankle pain and instability.
