Type III Radial Head Fracture

– Discussion: – comminuted fractures of the entire head; – classification: – type A: – fracture of the entire radial neck, with the head completely displaced from the shaft; – type B: – articular fracture involving the entire head, which consists of more than two large fragments; – each fragment is completely displaced from the … Read more

Zero Rotation Views

– Discussion:      – used to show ulnar variance;      – technique:            – shoulder is abducted 90 deg, the elbow flexed 90 deg, and forearm is held in neutral rotation;      – AP View:             – patient places the forearm flat on … Read more

Wrist Arthrodesis

– Indications:     – painful or unstable wrist joint w/ advanced destruction due to OA, RA, post traumatic arthritis, SLAC wrist, spastic flexion               contracture, degenerative scaphoid non-union, unsuccessful wrist arthroplasty, and Keinbock’s dz;     – this procedure is more beneficial for young, active pts or middle aged pts, but not for elderly pts; … Read more

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
