Lecture 7
• Ligaments of the Wrist
o Radial Collateral Ligament
▪ Connect the radius to the scaphoid and trapezium
o Ulnar Collateral Ligament
▪ Connects ulnar Styloid to the triquetrum
o Scapholunate ligament
▪ Holds the scaphoid and lunate together
• Triangular Fibrocartilage Complex (TFCC)
o Triangular = Shape
o Made of fibrocartilage
o Complex
o Function
▪ Suspends the carpals from the ulna
▪ Cushions the forces transmitted through
ulnocarpal axis
▪ Connects the ulna to the carpals
▪ Major ligamentous stabilizer of the distal
radioulnar joint
▪ Allows for gliding of carpals during wrist
movement
▪ Provides a flexible framework for rotational
movements in the wrist
• Bones of the Hand
