Template:Checked Articulationes manus include the following joints:
Articulatio radiocarpalis[edit | edit source]
- articulating surfaces: facies articularis carpalis radii, proximal row ossa carpi (os scaphoideum, os lunatum, os triquetrum), discus articularis
- The radius articulates directly 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 scaphoid, os lunate, os triquetrum form a socket for os capitatum, os hamatum; os trapezium, os trapezoideum forms a socket for the distal part of the os scaphoid
- the shape of a recumbent S
Articulatio ossis pisiformis[edit | edit source]
- stiff joint
- articulating surfaces: os pisiforme, os triquetrum
- the tendon m. flexor carpi ulnaris 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 ===
- 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
