– Discussion: – need to determien whether the fibrous has primarily affected flexion or extension; – need to determine either from radiographs or from MRI, whether incorrecttunnel placement, is the cause of the decrease motion and fibrosis; – also evaluate for patella baja; – … Read more
– Discussion: – musculoskeletal dz is characterized by congenital immobility of multiple joints. – there may be as many as 10 to 20 specific arthrogrypotic disorders, all with similar joint manifestations; – believed to be caused by oligohydrmnios & conditions limiting fetal movement; – joint develops in … 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
– 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: – Radiographic Evaluation – Blood Supply to Talus- Discussion: – may occur following talar neck fractures or may be atraumatic (from SLE, diabetes, MS ect); – absence of subchondral bone atrophy in talar dome on x-ray after 6 weeks following fracture implies AVN (see Hawkins Sign); – however, there is not direct correlation between development of AVN and … 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: – Antibiotic Menu – Osteomyelitis – Perioperative Prophylactic Antibiotics: – the main question we need to ask is what are we trying to accomplish? – obviously we want a strategy that prevents the infection of MRSA, MSSA, staph epi, and anaerobic infections; – giving ancef alone, … 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 which is basis for the pivot shift test; disrupted structures disruption of ACL disruption … Read more
