The metacarpophalangeal joints (MCP) are situated between the metacarpal bones and the proximal phalanges of the fingers. [1] These joints are of the condyloid kind, formed by the reception of the rounded heads of the metacarpal bones into shallow cavities on the proximal ends of the proximal phalanges . [ 1 ]
The neck of a metacarpal is a common location for a boxer's fracture, but all parts of the metacarpal bone (including head, body and base) are susceptible to fracture. During their lifetime, 2.5% of individuals will experience at least one metacarpal fracture.
The carpometacarpal joint connects the carpal bones to the metacarpus or metacarpal bones which are joined at the intermetacarpal articulations. In the fingers, finally, are the metacarpophalangeal joints (including the knuckles ) between the metacarpal bones and the phalanges or finger bones which are interconnected by the interphalangeal joints .
Examples include: [2] the wrist-joint; metacarpophalangeal joints; metatarsophalangeal joints; atlanto-occipital joints; These are also called ellipsoid joints. The oval-shaped condyle of one bone fits into the elliptical cavity of the other bone. These joints allow biaxial movements [3] — i.e., forward and backward, or from side to side, but ...
Joints of the hand, X-ray. The bones in each carpal row interlock with each other and each row can therefore be considered a single joint. In the proximal row a limited degree of mobility is possible, but the bones of the distal row are connected to each other and to the metacarpal bones by strong ligaments that make this row and the metacarpus a functional entity.
In anatomy, a biaxial joint is a freely mobile joint that allows movement in two anatomical planes. [1] An example of a biaxial joint is a metacarpophalangeal joint of the hand. [ 2 ] The joint allows for movement along one axis to produce bending or straightening of the finger, and movement along a second axis, which allows for spreading of ...
Jennifer Lopes was one of the many, many, mannnny celebrities to show up at the 15th annual Governors Awards last night, and truly turned it out for the red carpet.
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.
