[1] Symptoms include pain and a depressed knuckle. [2] Classically, it occurs after a person hits an object with a closed fist. [3]
Statistics show that generally more men are affected by Dieterich's than women in an estimated ratio of 3:2. [3] [5] The third (middle finger) metacarpal head has been reported to be the most common site of necrosis. [6] Though osteonecrosis is a fairly common condition, many cases of avascular necrosis of the metacarpal head go without being ...
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. Bennett's fracture (base of the thumb) is the most common. [4]

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 ...

Arthroplasty surgery for TMC OA removes part or all of the trapezium. [27] Surgery may also support the metacarpal by reconstructing a ligament using a tendon graft or weave. Surgery may also place something in the space where the trapeziometacarpal joint was, either a tendon wrapped up into a ball or a prosthesis.
