A healed fracture of the neck of the 5th metacarpal. Prognosis for these fractures is generally good, with total healing time not exceeding 12 weeks. The first two weeks will show significantly reduced overall swelling, with improvement in clenching ability showing up first.
The Bennett fracture is an oblique intraarticular metacarpal fracture dislocation, caused by an axial force directed against the partially flexed metacarpal. This type of compression along the metacarpal bone is often sustained when a person punches a hard object, such as the skull or tibia of an opponent, or a wall. It can also occur as a ...
The affected metacarpal head of the ring finger showed limited range of movement and chronic swelling. Through laboratory testing and based on the evolution of the pain, it was determined to be Dieterich's disease. The patient was initially suggested surgical treatment, but she rejected surgery due to acceptable functional status of the joint. [9]
Arthrodesis of the TMC joint is a surgical procedure in which the trapezium bone and the metacarpal bone of the thumb are secured together. They are held together by K-wires or a plate and screws until the bone will heal. Disadvantages include inability to flatten the hand. [27]
Carpometacarpal bossing (or metacarpal/carpal bossing) is a small, immovable mass of bone on the back of the wrist. The mass occurs in one of the joints between the carpus and metacarpus of the hand , called the carpometacarpal joints , where a small immovable protuberance [ 1 ] occurs when this joint becomes swollen or bossed.
The index metacarpal is the most firmly fixed, while the thumb metacarpal articulates with the trapezium and acts independently from the others. The middle metacarpals are tightly united to the carpus by intrinsic interlocking bone elements at their bases. The ring metacarpal is somewhat more mobile while the fifth metacarpal is semi ...
