Anatomical Overview The small joints of the hand are all hinge joints. The metacarpophalangeal joints (MCP) have a condylar structure, while the proximal interphalangeal joints (PIP) and distal interphalangeal joints (DIP) have a ball-and-socket shape. Their stability … Read more
Click the above“Good Medicine”, follow us Introduction The metacarpophalangeal joint primarily performs flexion and extension, with a few individuals able to hyperextend. The degree of flexion varies significantly. The metacarpophalangeal joint often dislocates due to external forces caused by finger sprains, punctures, or extreme dorsal extension or flexion. Depending on the position of the finger … Read more

Hand injuries are challenging to manage due to the unique anatomical structure of the hand. 01 Hand Anatomy All small joints of the hand are hinge joints. The metacarpophalangeal joint (MCP) has a saddle structure, while the proximal interphalangeal joint (PIP) and distal interphalangeal joint (DIP) have a ball-and-socket shape (Figure 1). Figure 1: Structure … Read more
Joint Structure The wrist joint consists of the radiocarpal joint and intercarpal joints. The radiocarpal joint is a condyloid joint formed by the concave distal end of the radius and the articular disc, which articulates with the convex surfaces of the scaphoid, lunate, and triquetrum bones. Some scholars do not consider the ulnar and pisiform … Read more
