Carpometacarpal Boss: An Unusual Cause of Extensor Tendon Ruptures

Year: 2014

Type: article

Abstract: Ruptures of tendons are rare and usually result from attritional wear caused by chronic inflammation or mechanical attrition against bony prominences. The classically described Vaughn-Jackson and Mannerfelt lesions result when a tendon ruptures from attritional wear on a dorsally subluxated ulna [15] or scaphoid osteophyte, respectively [9]. Rare reports exist of carpal bosses and intratendinous ganglions resulting in extensor tendon ruptures [3, 7, 16]. We describe a patient with a rupture of the extensor indicis proprius (EIP) and extensor digitorum communis (EDC) tendons to the index finger secondary to attritional wear against a carpometacarpal (CMC) boss of the index and middle fingers. The utility of ultrasound (US) in the diagnosis is described, as well as its treatment, and outcome of surgery.
