Carpal joint osteoarthritis and the formation of bony irregularities of the carpal bone cause closed flexor tendon ruptures. This report describes a case of a flexor profundus tendon closed rupture of the little finger due to asymptomatic pisotriquetral osteoarthritis in a 73-year-old woman, which required differentiation from tendon rupture due to hamate bony irregularity due to bone erosion. Computed tomography showed cortical bone irregularities of the hamate and the narrowing of the pisotriquetral joint space, and a bony spur on the radial side of the pisiform.

Pisiform and hamate coalition, a rare congenital anomaly, is most often identified as an asymptomatic incidental finding on radiographs. Some patients have symptomatic coalition with ulnar-sided wrist pain or ulnar nerve neuropathy from ulnar nerve compression. Sports activities such as cycling and weight lifting can cause compression of the ulnar nerve in the hand.
