Irreducible palmar metacarpophalangeal joint dislocation due to junctura tendinum interposition: a case report and review of the literature.

Three different anatomic structures have been reported to prevent reduction of a palmar dislocation of metacarpophalangeal joint: dorsal capsule, palmar plate, and a ruptured collateral ligament. In our case, extensor digitorum communis of the fifth finger and extensor digiti minimi subluxated on the ulnar side of the fifth metacarpal neck. Extensor digitorum communis of the fourth finger remained in its anatomic location. The junctura tendinum connecting the fourth and fifth extensor digitorum communis tendons slipped distal and then palmar to the metacarpal head, where it was trapped between the metacarpal neck and the base of the proximal phalanx. It was easily pulled out and the joint promptly reduced. Residual subluxation persisted due to rupture of the radial collateral ligament and the dorsal capsule. Repair restored joint reduction and stability. (J Hand Surg 2000; 25A:166-172.

A comparison of five tests for determining hand sensibility.

Three hundred seventeen normal fingers and 612 fingers in 153 hands with carpal tunnel syndrome were tested for sensibility using the Weinstein Enhanced Sensory Test (WEST) with calibrated monofilaments, by static two-point discrimination (s2PD) and moving two-point discrimination (m2PD), using the Disk-Criminator, and by Strauch's ten test. Equivalent Semmes-Weinstein monofilament (SWM) test values were also determined as a gold standard for comparison. With both the WEST and SWM test values, the norms for interpretation have an unacceptably wide latitude because of the use of an ordinal scale of increasingly unequal intervals. With the WEST and Disk-Criminator tests, some cases of early sensory loss were missed. The SWM test apparatus, although producing relatively reliable values, is not easily portable, and its use is time-consuming in a busy office; the WEST device is prohibitively expensive. The ten test is rapid, simple, and sensitive in evaluation. It measures sensibility on a continuous analog scale, and allows for multiple points of testing in the hand, with good inter- and intra-examiner reliability. It is accurate in detecting very early loss of sensibility. In addition, the ten test requires no instrumentation.

Trigger fingers and thumb: when to splint, inject, or operate.

Fifty trigger fingers were treated by splinting of the metacarpophalangeal joint at 10 to 15 degrees of flexion for an average of 6 weeks (range, 3 to 9 weeks). Another 50 trigger fingers were injected with 0.5 ml of betamethasone sodium phosphate and acetate suspension (Celestone) and 0.5 ml of lidocaine. All patients were followed up for a minimum of 1 year (range, 1 to 4 years). Treatment was successful in 33 (66%) of the splinted digits and 42 (84%) of the injected digits. Fifty percent of the 10 splinted thumbs and 70% of the 40 splinted fingers had a successful outcome. Of the 17 unsuccessfully treated digits in the splinted group, 15 were later cured with injections and 2 required surgery. All of the 7 unsuccessfully treated digits in the injected group were cured with surgery. Patients with marked triggering, symptoms of more than 6 months' duration, and multiple involved digits had a higher rate of failure in both groups. Splinting offers an alternative for patients who have a strong objection to cortisone injection.

Fractures of the sesamoid bones of the thumb.

Sesamoid fractures of the metacarpophalangeal joint of the thumb may be classified into two types: (1) with palmar plate intact, and (2) with palmar plate ruptured. In type 1, the patient maintains a normal flexion posture of the metacarpophalangeal joint as well as the ability to flex the metacarpophalangeal joint and interphalangeal joint. In type 2, the metacarpophalangeal joint assumes a hyperextension posture and the patient is unable to flex the metacarpophalangeal joint. Three cases are described to illustrate the two types of the injury. An open fracture of a thumb sesamoid associated with laceration of the palmar plate in a child was treated by reapproximating the palmar plate and the fracture fragments with sutures. Two additional closed fractures of the thumb sesamoid were treated by splinting the metacarpophalangeal joint in comfortable flexion for 2 to 3 weeks. Normal hand function was restored in all the three patients.
