Surgeons used Tommy's right arm palmaris longus tendon to replace his left medial collateral ligament. Wrist Joint a. Wrist Joint Bones 1. Metacarpals Metacarpals are wrist joints' bones of interest.
Wrists contain eight carpal and five metacarpals bones.
Carpals Eight carpals somewhat line up into two rows. Proximal rows somewhat join with radial and ulnar distal ends. From thumb to little finger, scaphoid and lunate bones articulate with radius' distal ends, while triquetrum and pisiform bones only line up with ulnas' distal ends. Pisiform bones lay against triquetrum bones that lay against hamate bones. Distal carpal rows articulate with proximal ends of five metacarpals.
