– See: – Blood Supply Femoral Head & Neck – Anatomy of Circulation: – mainly supplied by profunda femoris: – nutrient artery usually enters bone proximally and posteriorly along linea aspera; – usually there is only one nutrient artery (maximum of 2); – usually it comes of the 2nd perforating artery: – after giving off … Read more
– Discussion: – includes posterior 1/3 of lateral supporting structures; – it includes LCL, arcuate ligament, & exension of popliteus; – posterior 1/3 of the lateral ligamentous complex is reinforced by biceps, popliteus, & lateral head of gastrocnemius; – LCL: … Read more
– 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 also: 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; branch of trunk artery, median artery, temporarily replaces interosseous artery in supplying the hand; subsequently, ulnar … 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
