– 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
– Discussion: – pathophysiology: – compartment syndrome is elevation of interstitial pressure in closed fascial compartment that results in microvascular compromise; – as duration & magnitude of interstitial pressure increase, myoneural function is impaired & necrosis of soft tissues eventually develops; – intracompartmental pressure: … Read more
