– Discussion: – dislocations of the elbow associated with fracture are termed complex; – comprimise 49% of elbow dislocations; – most of these fractures are inherently unstable and require surgery; – prolonged elbow immobilization produces poor results. – surgery must achieve sufficient stability to allow … Read more

– See: Distal Radius Frx Menu / Intra-Articular Fractures of the Distal Radius – General Discussion: – frx was described by Abraham Colles in 1814, originally described as low energy extra articular frx of distal radius occuring in elderly individuals; – frx is typically dorsally displaced and angulated; – mechanism: … Read more
Discussion biosynthesis of collagen is initiated w/ osteoblasts; these intracellular events involve protein synthesis on endoplasmic reticulum to form 3 polypeptide chains, which make up protocollagen; protocollagen is hydroxylated to form procollagen, which is glyco-sylated at the endoplasmic reticulum; degree of hydroxylation of the lysine residue is important in that it will determine the number … Read more
– Discussion: – the biosynthesis of collagen involves many complex processes that are subject to biologic control; – these processes can be disrupted at any point by metabolic disorders such as: – scurvy; – lathyrism; – genetic collagen diseases: … Read more
