1. Ulnar styloid: distal continuation of olecranon
2. ECU: extensor or ulnar deviation dependent on wrist position

Finger ROM arc different with or without intrinsic function

The hand is not a specialized instrument (Lluch)

Functions of the hand: non-prehensile (precision or force - capable of both simultaneously) or prehensile

1. Tq most important bone; Tq is the engine, Scaphoid is the caboose

1. 25 1mm sections for wrist (3 Tesla MRI)

1. Tenodesis
2. Capsulodesis
3. Bone-tissue-bone: Remote (Navicular-cuneiform, iliac crest), Local
4. IC fusion

1. Modified Brunelli with its various modifications
2. 3 ligament reconstruction (Garcias-Elias, Stanley JHSA 06)
3. Modified Brunelli (Talwalker 2006)

1. decreased ROM
2. no change in ROM
3. capsulodesis: better pain relief
4. tenodesis: better SL angle

1. radial inclincation of finger is consequence of ulnar drift not cause
2. Ulnar subluxation is the most important cause of ulnar drift

1. release ADQM
2. plicate Radial saggital band
3. cross intrinsic transfer: biomechanically sound but not useful

1. according to Lluch is secondary to flexor tendon synovitis
2. plus PIPJ volar plate elongation
3. plus imbalance between flexors and extensor

1. In post-traumatic OA: soft tissues may be bigger problem than joint itself
