This paper presents the metacarpophalangeal (MCP) joint magnetic resonance images of the EULAR-OMERACT rheumatoid arthritis MRI reference image atlas. The illustrations include synovitis in the MCP joints (OMERACT RA magnetic resonance imaging scoring system (RAMRIS), grades 0-3), bone oedema in the metacarpal head and the phalangeal base (grades 0-3), and bone erosion in the metacarpal head an...

We present a rare case of stress fracture of the second metacarpal bone. A 14-year-old girl felt pain on the dorsal aspect of the right wrist without any history of major trauma, when she played a smash during a game of badminton. On the radiographs, periosteal reaction was detected on the ulnar aspect of the base of the second metacarpal bone. She was treated conservatively and she returned to...

a procedure characterised by simple excision of the trapezium (Gervis 1949). This procedure does not restore the trapezio-metacarpal joint, but rather creates a gap between the articular surfaces of the metacarpal and the scaphoid bones. Recently Swanson described a new technique, in which the trapezium was replaced by a silicone implant. Reports of the early results ofhis method and some techn...

The purpose of this study is to gain a better understanding of the changes due to osteoarthritis (OA) occurring in the thumb carpometacarpal (CMC) joint by comparing quantitative geometrical measurements in computed tomography scans of healthy and pathological joints in various stages of OA. The measurements were (1) the subluxation of the metacarpal on the trapezium, (2) distance from the scap...

The anomalous orientation of musculature of the first dorsal fibro-osseous compartment of the wrist is clinically relevant to De Quervian's stenosing tenosynovitis and reconstructive surgeries. Split insertion of the abductor pollicis longus (APL) is commonly found in chimpanzees, gorillas and gibbons. A comparable identical pattern of anomalous slips in humans is of anthropological and phyloge...

Basal joint osteoarthritis (OA) of the thumb is a common, debilitating disease that can have a significant adverse effect on hand function. When conservative therapies, including NSAIDS, corticosteroid injection, splinting, and thenar muscle strengthening exercises, are ineffective, operative therapies such as simple trapeziectomy and trapeziectomy with interposition of tendon and/or muscle are...

We report the cases of two men aged 35 and 33, who presented with similar injuries following a fall. They presented with pain isolated to the area of the index finger metacarpal base. Radiographs demonstrated an index metacarpal base fracture with a similar large ulnar-sided articular fragment extruded vol-arly. In the first patient the fragment was immediately adjacent to the remaining metacar...

Trapeziometacarpal joint (TMCJ) of the thumb is an unstable anatomically and depends on integrity normal functionality ligaments to prevent dislocation. Dislocation or subluxation trapezio-metacarpal generally appears more often as injuries accompanied with intraarticular fracture base first metacarpal trapezium. Isolated dorsolateral trapeziometacarpal osteoarthritis rather than traumatic lesi...

The majority of metacarpal fractures are closed injuries amenable to conservative treatment with external immobilization and subsequent rehabilitation. Internal fixation is favored for unstable fracture patterns and patients who require early motion. Percutaneous pinning usually is successful for metacarpal neck fractures and comminuted head fractures. Shaft and base fractures can be treated wi...
