– Discussion: – it is not a separate ligament but is condensation of fibers of origin of popliteus and helps form the arcuate complex: – arcuate ligament is a Y shaped condensation of fibers that courses from the fibular head, over the popliteus, to insert on the posterior capsule; … Read more
– See: – Adult Upper Limb Arteries: – Discussion: Upper Limb Development; – subclavian artery projects into the early upper limb bud & forms subclavian-axillary-brachial trunk; – its distal portion becomes interosseous artery that initially supplies plexus of arteries in the primitive hand; … Read more
– Discusison: – w/ application of severe AP force, hemipelvis rotates externally until posterior iliac wing contacts posteior sacrum; – continued force rips posterior SI ligaments, completely dissconecting hemipelvis from the sacrum; – APC III have highest rate of assoc injury, including retroperitoneal bleeding; – by definition then, an … Read more
– See: – X-rays for THR – X-rays for Femoral Neck Fractures – Discussion: – this view should demonstrate the iliac bone, sacrum, pubis, ischium, femoral heads and necks, and greater or lesser trochanters; – arcuate, iliopubic, ilioischial, and acetabular teardrop lines, sacral foramina, & SI … Read more
– indications: – allows unobstructed view of articular surface of acetabulum; – technique: – proximal bolt is inserted in the iliac wing in its superior portion, just distal to thickened crest; – proximal bolt must pass through portion of ilium in continuity w/ sacrum (or frx … Read more
– Definition: – medial plateau of the tibia rotating excessively forward & externally on femur as the joint opens on the medial side; – torn structures: – MCL; – posterior oblique ligament; – ACL; … Read more
– See: Smith Peterson Approach – Discussion: – major problems with the Watson Jones technique are dealing w/ gluteus medius & minimus, which lie over anteior capsule and must be damaged or cut to obtain adequate exposure; – original Charnely technique used anterolateral approach w/ pt supine, osteotomy of greater troch, … Read more
– Discussion: – defined as excessive forward rotation of tibial plateau w/ excessive lateral opening of the joint; – there is excessive internal rotation of tibia on femur in flexion; – as knee extends, subluxation is reduced by the bony stability, and a jerk is noted … Read more
– Seee: Anterior Pelvic Injuries – Discussion: – symphyseal diastasis and/or longitudinal rami fractures; – these injuries result from relatively anterior or posterior forces applied to the anterior or posterior superior iliac spine areas; – this gives rise to forces that tend to disrupt anterior pelvis, either by fracturing … Read more
– See: – Arthroscopic Reconstruction – Historic Operations – Revision Bankart Procedure – Bankart Repair: – reattachment of the capsule and glenoid labrum to the glenoid lip; – subscapularis is carefully divided to expose the capsule, and is reapproximated without any overlap … Read more
