Data Trace Editor – Discussion: – large bony fragment is avulsed by the tendon and is humg up at the level of distal pulley (A4); – technically the fragment is distal to the A4 pulley; – long vinculum remains intact; – tendon may separate from bony fragment … Read more
– See: Collagen Discussion: – Discussion: – in Dupuytren’s, there is an increase in type III collagen (which is similar to scar tissue); – normal fascia is mostly of type I collagen; – Ehlers-Danlos Syndrome: – see collagen disorders; – at least 9 types of Ehlers-Danlos syndrome have been defined; – mutations in Type III … Read more
– See: Posterior Frx Dislocations of the Hip – Discussion: – prognostic features: – long term results are proportional to the degree of intial trauma – this explains percentage of good results progressively decreasing from type II to type V injuries. … Read more
– Discussion: – if the frx needs a reduction, then the frx is not a type I but a type II; – posterior cortex remains intact, making it a greenstick frx; – technically a type II frx implies posterior displacement, but frequently there will also be medial impaction w/ … Read more
– See: spine in osteoporosis – Discussion: – caused by long term calcium deficiency; – there is an age related decline in renal production of 1,25 Vit D with subsequent hyperparathyroidism & bone loss; – these pts have already lost most of the bone they ever will lose; … Read more
– Discussion: – displaced, stable frx; – frx fragments are displaced > 2-3 mm, but collateral ligaments are intact; – frx may be non-comminuted (Type IIA) or comminuted (Type IIB). – no sign of subluxation; – Non Operative Treatment: – immobilized in mid flexion, these … Read more
– PreOp Planning – most important step in reconstruction of any intra articular frx, is to expose the fracture w/o devasclarizing the fragments; – treatment plan: – open reduction; – elevation of the depressed plateau; – bone … Read more
– Discussion: – most common form; – distal end is located in the decussation of the FDS – small chip of bone is taken off w/ flexor tendon; – tendon retracts to level of PIP joint or distal to PIP, & long vincululm may remain intact; – a small … Read more
– Discussion: – seen in older children and adolescents; – fragment of metaphysis remains attached to posterior medial epiphysis; – articular surface is tilted inferiorly; – deforming forces: – humeral shaft is drawn upward, forward, & inward due to pectoralis major, latissimus, … Read more
– See: collagen – Discussion: – accounts for over 50 percent of the dry wt of cartilage; – type II collagen is also found in small amounts in vitreous gel and in a number of other tissues during early development; – type II collagen mutations: – mutations in type II collagen as a cause of … Read more
