Wrist Arthrography

– Discussion:     – arthrography may be used in diagnosis of carpal instability because it is technically easy & is only minimally invasive;     – normally there should be no communication between the radiocarpal, mid-carpal, and distal radial-ulnar joints;     – it is noteworthy that in normal wrists there may be communications … Read more

Wrist Arthroscopy

– Positioning and Preparation: – joint is distended w/ finger traps (to index and long fingers) w/ about 10 lbs, using a pulley system; – counter traction is applied to the arm w/ use of a second 10 lb pulley – this allows the elbow to be flexed 90 deg; – gravity assistant inflow; – initially … Read more

Wrist Disarticulation

– Discussion:     – wrist disarticulation: include the removal of the radius and ulna to styloid processes;     – shape of stump remains bulbous, thus permitting prosthetic attachment, leaving the elbow free and preserving full pronation & supination;     – wrist disarticulation retains distal radio-ulnar joint preserves more forearm rotation, & retaining distal radial flare dramatically … Read more

Wrist Joint Aspiration & Arthroscopy

– Discussion:       – joint is entered dorsally;       – if there is any difficulty in entering Wrist Joint, hand can be suspended in Chinese finger traps to help open the joint space;       – there are 2 main entry sites, 3-4 & 4-5 sites;         … Read more
