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...

Carpo-metacarpal dislocations are rare traumatic injuries resulting from violent trauma; they mostly observed in young subjects. The spatular form is often accompanied by metacarpal fractures. We report a clinical case of complete dorsal carpo-metacarpal dislocation. This was 34-year-old patient, admitted for closed trauma the right hand, whom examination noted edema hand. radiological workup s...

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...

Metacarpal (MCP) base fractures are less commonly encountered than diaphyseal or metacarpal neck fractures. These are difficult injuries to diagnose and are challenging to treat. Neglect of these injuries, either by missed diagnosis or by inadequate treatment, causes significant disability due a poorly functioning carpo-metacarpal joint. There have been several developments in the management of...

Most stress fractures occur in the lower limbs and are rarely observed in the upper limbs. The second metacarpal is the longest of all the metacarpals and has the largest base, articulating with the trapezium, trapezoid, capitate, and third metacarpal. In athletes, stress fractures in non-weight bearing joints are uncommon. Therefore, the shaft of the second metacarpal bone undergoes a higher l...

To measure the motions of the trapeziometacarpal joint of the thumb quantitatively, a roentgenographic method was developed and tested using T-shaped metal markers, a special cassette-holder, and biplane roentgenograms. Two experiments were performed. In the first one, the metal markers were fixed to the trapezium and third metacarpal in ten cadaver specimens, and a fixed spatial relationship b...

BACKGROUND Spiral metacarpal fractures can result in shortening of the metacarpal shaft, which may lead to extension lag at the metacarpophalangeal joint and reduced grip strength. These fractures have been surgically treated to restore metacarpal length; however, there are complications associated with surgery, postoperative management and wound healing, which further threaten power recovery i...

The metacarpus of Indian Blackbuck comprised of two metacarpal bones. The large metacarpal bone consisted of fused III and IV metacarpals. The shaft of the metacarpus presented two surfaces and two borders. The dorsal surface was smooth and semi-cylindrical in outline. The palmar surface was flat in outline and it presented a deep longitudinal groove which possessed similar foramina. These fora...

we present two patients with a displaced fracture of the small finger metacarpal base, where the shaft of the small finger metacarpal was wedged between the bases of the ring and small finger metacarpals. the striking appearance on radiographs led to initial recommendations for surgery, but both patients preferred non-operative treatment and did well in the short term without surgery
