Impingement of a fibroma of the extensor tendon sheath on the extensor retinaculum


Deep lacerations to the forearm can cause impaired movement of the digits. This report describes the presentation and management of a self-harmer who presented with loss of motion of her ring finger. Surgical exploration unexpectedly demonstrated the cause to be a fibroma of the tendon sheath impinging on the extensor retinaculum. Full recovery was demonstrated at sixmonth review following removal of the lesion.
