OBJECTIVE The aim of this study was to establish an indirect, easy-to-use, predictable and safe means of obtaining the true degree of displacement of fractures of the neck of the fifth metacarpal bone, through oblique radiographic views. METHODS An anatomical specimen from the fifth human metacarpal was dissected and subjected to ostectomy in the neck region. A 1-mm Kirschner wire was fixed t...

INTRODUCTION Isolated dislocations of the trapezio metacarpal joint without associated fracture has been reported very rarely in the literature. There are reports of associated injuries like fracture of the trapezium, dislocation of the metacarpophalangeal joint and fractures of the base of the thumb metacarpal. CASE REPORT Authors report a case of isolated carpometacarpal dislocation of the ...

Splinting for the common osteoarthritis of the carpometacarpal (CMC) joint of the thumb is infrequently described in the literature, but the few splints that are described include one or both adjacent joints. This paper describes the design and biomechanics of a custom-molded thumb CMC immobilization splint that excludes the thumb metacarpophalangeal and wrist joints. The problem of the imbalan...

A 27-year-old male boxer presented with pain in the dorsum of right wrist and difficulty getting a firm grip on his hand for 2-month duration. On examination, he had swelling over dorsal aspect wrist. Physical examination revealed bony hard mass at junction third metacarpal capitate bones. The persisted despite conservative treatment patient was referred to our hospital further evaluation. Radi...

Bennett's fracture is the retention of bone to which beak ligament attached, and dorsoradial proximal subluxation base metacarpal detached from this part. Key features are intra-articular fracture, oblique pattern, volar-dorsal fragment. The medial small piece remains in place maintains its relationship with second finger via volar ligament.

Avulsion fractures of the radial wrist extensor from the metacarpal base are rare injuries, and have previously been reported in only a few papers. Although 2 cases of closed rupture of the extensor carpi ulnaris (ECU) were mentioned in 1 report, no case of avulsion fracture of the ECU from its insertion was found in the literature. We recently encountered such a case. The patient, a machine op...

BACKGROUND The aim of this study was to investigate clinical outcomes of fifth metacarpal neck fractures using antegrade single elastic nail and to explore ideal puncture point to avoid iatrogenic ulnar nerve injury. METHODS A single elastic nail with suitable diameter was used in 27 cases of fifth metacarpal neck fractures with dorsal angulation over 45°. An initial entry point was perforate...

A variety of fractures occur at the base of the first metacarpal bone, the best known being that described by Bennett in 1882. A group of more comminuted fractures also involving the carpo-metacarpal joint were later described by Rolando (1910). Transverse fractures at the lower end of the metacarpal bone were mentioned by Roberts (1938) in a review of all fractures occurring in the hand. Much ...

DESCRIPTION A 13-year-old baseball catcher presents with left thumb pain after a collision with another player.

Injuries to the thumb are predominated by fractures of the proximal phalanx, ligamentous injuries about the metacarpophalangeal joint, and metacarpal base fractures. This article will attempt to summarize recent advancements within the realm of thumb trauma, with particular attention to Bennett fractures, Rolando fractures, and ulnar collateral ligament injuries.
