The rationale is that ligament reconstruction(LR) helps maintain the gap between the metacarpal and the scaphoid, and that a larger gap is associated with greater comfort and capability. [32] Again these possibilities are not supported by experimental evidence. During this procedure the anterior oblique ligament is reconstructed using the FCR ...
In human anatomy, the radial (RCL) and ulnar (UCL) collateral ligaments of the metacarpophalangeal joints (MCP) of the hand are the primary stabilisers of the MCP joints. [1] A collateral ligament flanks each MCP joint - one on either side. Each attaches proximally at the head of the metacarpal bone, and distally at the base of the phalynx.
Hypertrophic osteoarthropathy is a medical condition combining clubbing and periostitis of the small hand joints, especially the distal interphalangeal joints and the metacarpophalangeal joints.
Carpal tunnel syndrome (CTS) is a nerve compression syndrome associated with the collected signs and symptoms of compression of the median nerve at the carpal tunnel in the wrist. Carpal tunnel syndrome usually has no known cause, but there are environmental and medical risk factors associated with the condition. [1] [6] CTS can affect both wrists.
Ligamentous laxity or ligament laxity can appear in a variety of ways and levels of severity. In most people, ligaments (which are the tissues that connect bones to each other) are naturally tight in such a way that the joints are restricted to 'normal' ranges of motion. This creates normal joint stability.
The metacarpal bones are connected together by dorsal, palmar, and interosseous ligaments. The dorsal metacarpal ligaments ( ligamenta metacarpalia dorsalia ) and palmar metacarpal ligaments ( ligamenta metacarpalia palmaria ) pass transversely from one bone to another on the dorsal and palmar surfaces.
The carpometacarpal (CMC) joints are five joints in the wrist that articulate the distal row of carpal bones and the proximal bases of the five metacarpal bones.. The CMC joint of the thumb or the first CMC joint, also known as the trapeziometacarpal (TMC) joint, differs significantly from the other four CMC joints and is therefore described separately.
At the same time, the increasingly taut collateral ligaments of the MP joints cancel out the abduction-adduction component to increase the force of flexion (resulting in a strong grip). At full flexion, the transverse metacarpal ligament restricts the interossei. [3]
