– Discussion: – in elderly pts w/ comminuted frx, excision of up to 50% of olecranon can be well tolerated (no instability) – if distal surface of semilunar notch of ulna & coronoid are not injured upto 80% of olecranon may be excised w/o producing instability; – … Read more
Discussion – descision to excise the head of the radius depends associated elbow injuries as well as severity of radial head frx; – it has been determined that the stabilizing effect of radial head comes into play only when the MCL ligament has been disrupted, which explains why excision of radial head (w/ … Read more
– Discussion: – radial head frx plus dislocation of distal RU joint (& interosseous membrane disruption); – mechanism: fall from height; – in this type of frx, radius will also migrate proximally if radial head is excised; – if injury is not found when it is acute, pt may develop severe wrist pain from radial migration … Read more
– See: – Obstetrical Paralysis: – Upper Trunk Brachial Plexus Injuries in Adults; – Discussion: – most common birth related neuropraxia (about 48%); – lesion of C5 & C6 roots are usually produced by widening of the head shoulder interval (in some cases C7 is involved as … Read more
– See: – Metaphyseal Artery – Nutrient Artery – Periosteal Artery – Discussion: – in femoral and radial heads which are almost entirely covered by cartilage, – vessels enter in region between articular cartilage & growth-plate cartilage, and hence, the … Read more
– See: Anterior Interosseous Nerve Sydrome: – Site of Proximal Forearm Compression; – supracondylar process of the humerus and struther’s ligament: – median nerve may be compressed as it passes under the bondy spur – pt c/o of weak hand grip and in pronating, … Read more
– EMG – General Discussion: – conduction velocity in the ulnar nerve across the elbow is slowed compared with the velocity in the forearm segment; – as noted by Kaempffe and Farbach (1998), abnormal EMG results are associated w/ poor surgical outcome; – position of elbow during EMG/NCS: … Read more
– Adult Condylar Fractures: (surgical technique) – capitellar and coronal shear frx – distal humerus frx: – lateral condyle frx: – medial condyle frx: – distal humeral non union: – ulnar nerve in condylar fractures: – Pediatric Elbow Injuries – distal humeral physeal separation: – lateral condyle frx, pediatric – medial epicondyle frx of … Read more
– See: Elbow Dislocations in Adults: – Discussion: – elbow dislocations in children are a relatively uncommon; – peak incidence occurs in adolescence between 11-15 years. – posterior dislocations are most common type; – posterior dislocation usually results from fall on outstretched hand w/ forarm supinated & … Read more
– Discussion: – RA manifests itself in many ways in elbow joint, including nodules and bursae, synovitis, progressive joint destruction, antecubital cysts, & ulnar or, rarely posterior interosseous palsy; – note that involvement of the RA elbow is infrequently an isolated and therefore it is important to consider possible involvement in the wrist … Read more
