PHTY101 Lecture Notes - Lecture 4: Wrist, Midcarpal Joint, Triquetral Bone
Document Summary
Topic 4: joints of the wrist and hand. Rhyme: six little teapots try to catch heat. Arranged in two rows: proximal row; six little teapots. Radiocarpal joint: scaphoid, lunate, and triquetral: distal surface of radius, distal surface of inf ru jt disc. Midcarpal joint: scaphoid, lunate, and triquetral trapezium, trapezoid, capitate, hamate. 4. 2 identify and classify the radiocarpal (wrist) joint and identify and/or describe its: articular surfaces joint capsule ligaments, dorsal radiocarpal, palmar radiocarpal, palmar ulnocarpal, radial collateral, ulnar collateral, movements. Collaterals radial collateral of wrist limits adduction: ulnar collateral of wrist limits abduction, dorsal and palmar radiocarpal fibres generally run inferiorly and medially, ensuring that the carpals move with the. R and u during pronation and supination dorsal limit flexion palmar limit extension. 4. 4 identify and classify the midcarpal joint and identify and/or describe its: articular surfaces, capsule. Ligaments: palmar intercarpal, dorsal intercarpal, radial collateral, ulnar collateral, movements.
