Gouty infiltration of a flexor tendon simulating rupture.

A 28-year-old hyperuricemic man injured his left long finger and presented with a possible rupture of the flexor digitorum profundus. Operative exploration revealed gouty infiltration of the flexor tendon within its fibrous synovial sheath. Urate crystal deposition in tendons is rare. Superimposed trauma was a possible predisposing factor.
