Radius and Ulna – Fractures
– Discussion: – distal radioulnar subluxation/dislocation (see TFC Injury) – tear of the lunotriquetral – ulnocarpal impingement syndromes – pisotriquetral osteoarthritis – pisotriquetral loose bodies – subluxation/dislocation of the pisiform – fractures (ulnar styloid Process) – chondromalacia – calcific tendinitis – medial carpal instability – radioulnar arthritis – subluxation of the ECU The ulnar impaction … Read more
– Discussion: – indications are essentially the same as for radial shortening; – advocates of ulnar lengthening for Kienbock’s dz base their theorem on the fact that an ulnar lengthening procedure decreases the load across the radiolunate joint; – this procedure is ideally suited for pts … Read more
– Discussion: – see: elbow flexion contracture; – indicated for patients w/ loss of motion (out of functional range from 30 to 130 deg) due to anterior and posterior osteophytes; – PreOp Planning and Positioning: – patient is supine w/ bump placed under shoulder, and arm folded across chest; … Read more
– Discussion: – often patients will note pain weeks to months after the cast is removed; – w/ excessive dorsal tilt, will often develop a symptomatic ulnar mid-carpal instability (or carpus adaptive DISI); – in the report by Taleisnik and Watson (1984), the average amount … Read more
– Medullary bone: – decreased in quantity, & trabecula are thin & irregular; – feature that most sig helps to establish the dx is presence of layer of unmineralized bone (osteoid seam) surrounding mineralized segment; – trabeculae & cortex have less bone, & is surrounded by a layer of unmineralized bone (osteoid seam) – osteoid seams; … Read more
– See: Forearm Extensors : – Anatomy: – origin: 2 heads from lateral epicondyle & middle 1/3 of posterior ulna; – insertion: – posterior surface of base of 5th metacarpal; – ECU is the only wrist extensor that lies in its own fibro-osseus tunnel; – action: extends and adducts the hand at the wrist; – … Read more
– Discussion: – first performed by Darrach in 1911 in New York City. – Indications: – for relief of pain following distal RU disruption and/or RU arthritis; – for symptomatic malunion of Colle’s frx in elderly patients, especially when stiffness is present; – procedure is generally performed … Read more

– See: – Radial Ulnar Joints – Rheumatoid Arthritis – Discussion: – ulnar caput syndrome results from synovitis stretching ulnar carpal ligaments; – there is dorsal dislocation of distal ulna, supination of carpus on hand, volar subluxation of the ECU; – left untreated, ulnar translocation … Read more
See: – Thompson is especially suitable for the middle third of the radius, however, it is not suitable for distal third radial frxs because the posterolateral application of the plate may interfere w/ outcropping tendons to thumb, disturbing function; – care is taken with this approach to avoid injury to the radial nerve and therefore … Read more
