PHTY101 Lecture Notes - Lecture 6: Wrist, Midcarpal Joint, Articular Disk
Document Summary
Note: extrinsic have attachments up to radius / ulnar or disk, intrinsic are entirely within the carpals. Note: for these fibres generally run inferiorly and medially, ensuring the the carpals move with the radius and ulnar during pronation and supination. Ie the carpals will come with the radius in pronation and supination. Palmar ulnocarpal: this goes from the end of the ulnar, across to the front of the carpals. Radial collateral: this is capsular, limits adduction (ie ulnar deviation this is more common as smaller styloid process) Ulnar collateral: this is capsular, limits abduction (ie radial deviation: movements, flexion and extension (transverse axis) ie palmarflexion and dorsiflexin, abduction and adduction (anterposterior axis) ie radial and ulnar deviation. 4. 3 identify and classify the intercarpal joints: articular surfaces, this is the articulation between the individual carpal bones, this is a synovial plane joint, synovial capsule, the synovial cavity may communicate with radiocarpal joint.
