A boxer's fracture is the break of the fifth metacarpal bone of the hand near the knuckle. [4] Occasionally, it is used to refer to fractures of the fourth metacarpal as well. [1] Symptoms include pain and a depressed knuckle. [2] Classically, it occurs after a person hits an object with a closed fist. [3]
The dorsal surface of the body is divided by an oblique ridge, which extends from near the ulnar side of the base to the radial side of the head. The lateral part of this surface serves for the attachment of the fourth interosseus dorsalis ; the medial part is smooth, triangular, and covered by the extensor tendons of the little finger .
Age. The risk of most causes of joint pain increases with age. This may be due to increased wear and stress on joints over time and a higher likelihood of other underlying medical conditions ...
The TMC joint is a synovial joint between the trapezium bone of the wrist and the metacarpal bone at the base of the thumb. This joint is a so-called saddle joint (articulatio sellaris), unlike the CMC joints of the other four fingers which are ellipsoid joints. [17] This means that the surfaces of the TMC joint are both concave and convex.

The ED inserts into the middle and distal phalanges to extend the fingers and wrist. Opposite the head of the second metacarpal bone, the EI joins the ulnar side of the ED tendon to extend the index finger. The EDM has a similar role for the little finger. The ECU inserts at the base of the 5th metacarpal to extend and
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]
The intermetacarpal joints are in the hand formed between the metacarpal bones. The bases of the second, third, fourth and fifth metacarpal bones articulate with one another by small surfaces covered with cartilage. The metacarpal bones are connected together by dorsal, palmar, and interosseous ligaments.
