Document Summary

Intra-articular discs (mensci: peripheral labrum, fat pads, bursae, synovial plicae, classifications of synovial joints based on mechanical analogy. Spinning on one member around a single axis of rotation analogy. Triplanar motion (flexion, extension, abduction, adduction, and internal/external rotation) Typical motions include slide (translation) or combined slide and rotation. Biplanar motion; spin between bones is possible but may be limited by the interlocking nature of the joint. Biplanar motion; either flexion-extension and abduction-adduction, or flexion-extension and axial rotation (int/ext rotation) with a concave trough. Spherical convex surface paired with a concave cup. Relatively flat surfaces apposing each other, like a book on a table. Each member has a reciprocally curved convex surface oriented at right angles to the other, like a horse rider and a saddle. Mostly spherical convex surface that is enlarged in one dimension like a knuckle; paired with a shallow concave cup. Carpometacarpal joints of digits ii-v (aka modified plane joints)
