Background: Since there is not a definite cause for Kienbock's diseases despite appropriate knowledge of lunate bone blood supply, so great debate about the ideal treatment protocol diseases. Objective: The aim this study to assess outcome combining distal capitate shortening and fusion base third metacarpal disease (Lichtman stage II or IIIA) with neutral ulna variance. Methods: Twenty patient...

DESCRIPTION A 58-year-old woman was involved in a motor vehicle accident. She sustained diffuse swelling over the dorsum of her dominant hand along with a hematoma extending from the level of the metacarpophalangeal joint to the wrist. There was also extensive bruising over the palmer aspect. There was no obvious neurovascular compromise.

PURPOSE Previously, we studied normative and reliability data of palmar thumb abduction measurements (conventional goniometry, the Pollexograph thumb, the Pollexograph metacarpal, the Inter Metacarpal Distance, the American Society of Hand Therapists method, and the American Medical Association method) in healthy adults. Because many interventions aiming to improve palmar abduction are performe...

Ten patients with metacarpophalangeal joint locking of the thumb were studied. Three of them underwent surgical release. During surgery, it was found that the radial sesamoid was seated in a cartilage defect on the volar aspect of the metacarpal head. It appeared that the defect was created by the proximal edge of sesamoid. When the abductor pollicis brevis and flexor pollicis brevis muscles we...

BACKGROUND There is no robust evidence of the best operative treatment for displaced unstable metacarpal neck fractures. Numerous constructs are used in the fixation of metacarpal neck fractures. Currently, two common methods are dorsal locking plate and K-wire fixation. A new metacarpal sled fixation system for metacarpal neck fracture was designed to provide fracture stability but limit disse...

Extraarticular metacarpal fractures are common during childhood, and osseous healing is the rule. We have treated two patients with delayed and nonunion of three metacarpal shafts. One patient sustained closed second and third metacarpal fractures, and the other sustained an open second metacarpal fracture. Both injuries were crush-type of significant force. Although initial treatment seemed ap...

Avulsion fracture of the base of the second metacarpal is an unusual injury, and the cause in the few cases reported in the literature was a fall on a volarly flexed wrist. A case of this rare injury suffered in a sport related accident by a semiprofessional rugby player is reported. It was treated with open reduction and internal fixation after failure of conservative management.

Human hands, when compared to that of apes, have a series of adaptations to facilitate manipulation. Numerous studies have shown that Australopithecus afarensis and Au. africanus display some of these adaptations, such as a longer thumb relative to the other fingers, asymmetric heads on the second and fifth metacarpals, and orientation of the second metacarpal joints with the trapezium and capi...
