Ligaments of the Wrist Wrist: Ulnar collateral ligament Radial collateral ligament Transverse carpal ligament Property of CTE Joint Venture

Ligaments of the Hand Fingers: Collateral ligaments Property of CTE Joint Venture

Articulations of the wrist Radiocarpal joints Intercarpal joints Carpometacarpal joints

Carpal Ligaments Wrist is stabilized by anterior, posterior, and interosseous ligaments. Play important role in stabilization of the wrist complex. Identification of specific ligament difficult if not impossible.

Flexor Retinaculum Strong fibrous band that restrains or holds in place tissue, muscles or organs Restraining structure for the flexor tendons

Extensor retinaculum Strong fibrous band Restraining structure for the extensor tendons

Wrist Motion Bone structure allows 6 different motions Flexion Extension Adduction (Ulnar deviation) Abduction (Radial deviation) Pronation Supination
