Articulatio radiocarpalis[edit | edit source]
- articulating surfaces: facies articularis carpalis radii, proximal row of ossa carpi ( os scaphoideum , os lunatum , os triquetrum ), discus articularis
- the radius directly articulates with the ossa carpi
- between the ulna and the ossa carpi is the discus articularis
- meniscoid process
Articulatio mediocarpalis[edit | edit source]
- articulating surfaces: os scaphoideum, os lunate, os triquetrum form a socket for os capitatum , os hamatum ; os trapezium , os trapezoideum form a socket for the distal part of the os scaphoideum
- the shape of a recumbent S
Articulatio ossis pisiformis[edit | edit source]
- stiff joint
- articulating surfaces: os pisiforme , os triquetrum
- the flexor carpi ulnaris tendon emerges from the os pisiforme
- the flexor carpi ulnaris tendon is divided into 2 ligaments
- lig. pisohamatum (to hamulus ossis hamati)
- lig. pisometacarpale (to the base of the 4th + 5th metacarpals)
Articulationes intercarpales[edit | edit source]
- joints with little mobility between the carpal bones of one row
- ligamenta intercarpalia interossea
Articulationes carpometacarpales[edit | edit source]
- articulating surfaces: distal row of carpal bones, base of metacarpal bones
Art. carpometacarpalis pollicis[edit | edit source]
- saddle joint
- articulating surfaces: basis ossis metacarpi I, os trapezium
- movements: palmar flexion, dorsiflexion, abduction, adduction, rotation, opposition, reposition
