This is a syndrome of chronic pain with changes of temperature and colour of the skin. Other general complications include superficial radial nerve damage and postoperative wound infection. After arthrodesis, non-union, in which fusion of the trapezium bone with the metacarpal bone fails, occurs in 8% to 21% of the cases. [27]
The trapezium is an irregular-shaped carpal bone found within the hand. The trapezium is found within the distal row of carpal bones, and is directly adjacent to the metacarpal bone of the thumb. On its ulnar surface are found the trapezoid and scaphoid bones. [1]: 708
The carpometacarpal joint of the thumb (pollex), also known as the first carpometacarpal joint, or the trapeziometacarpal joint (TMC) because it connects the trapezium to the first metacarpal bone, plays an irreplaceable role in the normal functioning of the thumb. The most important joint connecting the wrist to the metacarpus, osteoarthritis ...
The hand is subdivided into three parts: [citation needed] Wrist; Metacarpus; Digits; The wrist consists of eight small carpal bones. Each of these carpal bones has a different size and shape.

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 ...
