Flexor Digitorum Profundus Tendon

We report three patients who sustained a rupture of the flexor digitorum profundus tendon to the small finger within the carpal tunnel. There was a common mechanism of injury, each rupture occurred during resisted flexion of the digit with the metacarpophalangeal joint in extension. All the patients were male, one patient had an asymptomatic undiagnosed fracture of the hook of hamate, one patient had radiological evidence of piso-triquetral osteoarthritis. In each case, an attrition rupture was confirmed at surgery.

Spontaneous rupture of flexor tendons within the carpal tunnel is rare in the absence of rheumatoid arthritis. Other predisposing conditions such as gout, infection, pisotriquetrial osteoarthritis, as well as hook of hamate fracture non-union, have previously been reported. However, tendon ruptures of the hand in the presence of acromegaly, as well as spontaneous ruptures within the carpal tunnel, have not been described in the literature.

Flexor Digitorum Profundus Tendon

We investigated residual digital flexor pulley strengths after 75% excision of the A2 and A4 pulleys. For direct pull-off tests, A2 and A4 pulleys from cadaveric fingers were tested by pulling on a loop of flexor digitorum profundus tendon through the pulley. For functional loading tests, fingers were positioned with the metacarpophalangeal joint flexed to 90° for A2 testing, and with the proximal interphalangeal joint in 90° flexion for A4 testing (with all other joints in full extension). Excision of 75% of A2 and A4 pulleys reduced pulley strengths determined by both testing methods. For the functional loading tests, which are more clinically relevant, mean tendon forces at failure after partial excision of A2 and A4 pulleys were 224 and 131 N respectively, which is sufficient to withstand flexor tendon forces expected during activities of daily living.

Flexor Digitorum Profundus Tendon

We experienced a rare case of carpal tunnel syndrome and rupture of the flexor digitorum profundus tendon to the index finger with a scapholunate advanced collapse wrist. We speculated that the lunate that had extruded into the carpal tunnel compressed the median nerve and caused wear of the flexor tendon following neglected perilunate subluxation. Carpal tunnel release, opponensplasty by palmaris longus tendon transfer, and a bridge graft by a half-slip of the flexor carpi radialis tendon resulted in recovery of pinch function and improvement in numbness of the hand.
