Entrapment of the metacarpophalangeal joint of the middle finger. Case report.
Locking of the second metacarpal joint is common, but locking of other metacarpal joints is unusual. We present a case, in which the joint of the third finger locked and the mechanism was an osteophyte catching of the ulnar accessory collateral ligament. In such a case, the joint should be explored through a palmar approach. Conservative treatment is not recommended.
