Traumatic dislocation of the metacarpophalangeal joint is a relatively uncommon injury. The dislocation may be easily reducible (ie, simple) or require surgical intervention (ie, complex). The flexor tendons, lumbrical muscle, natatory ligament, and superficial transverse metacarpal ligament combine with the displaced volar plate to create a tight noose, preventing reduction. Surgical approach ...

Proper case selection, rigid stabilization, and efforts to prevent or treat infection will improve the success rate of metacarpal and metatarsal bone fractures in the horse. Metacarpal and metatarsal fractures in horses need not be associated with a poor prognosis.

The adductor pollicis muscle was studied in fifty hands of Japanese adult cadavers of both sexes. The radial portion of the oblique head of the adductor pollicis muscle has carpal and metacarpal origins and an insertion into the wing tendon of the extensor apparatus. This portion was located dorsal to the palmar metacarpophalangeal articular nerve and superficial palmar metacarpal artery. Thus,...

Primary tuberculosis osteomyelitis of metacarpal bone is rare. The majority of cases occur in children and young adults and there is difficulty in diagnosis mainly in young children. We report a new case in children aged of 3 years, presenting a swelling on the dorsal side of her right hand since 8 months. X-ray showed an expansile, cystic and lytic lesion involving the little finger metacarpal...

The metacarpophalangeal (MP) joint is resistant to injury due to its strong capsuloligamentous structures, which include the volar plate and deep transverse metacarpal and collateral ligaments. Complex MP joint dislocations are, by definition, irreducible by closed means and require open reduction, as the volar plate becomes entrapped between the metacarpal head and proximal phalanx. The dorsal...

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...
