– Discussion: – 4 segment frx is most difficult to treat & is assoc w/ poorest results; – vascular supply to the humeral head – added to problems of three part frx, namely delayed union or non union, is avascular necrosis of the humeral head; – the … Read more
– Above the Level of the Pectoralis: – frx above level of pectoralis allows proximal frag to abduct & rotate internally, owing to action of rotator cuff; – pectoralis has greatest influence on shaft segment & tends to displace it medially and anteriorly; – Above the Deltoid: … Read more
– Fluid Management: – need for continuous outflow; – note that a small amount of continuous outflow will allow for clear visualization and decreased inflow pressure settings; – Bernoulli principle: bleeding can be decreased by decreased fluid turbulence due to egress of fluid from portal sites; – note that continuous outflow will allow reduced pump … Read more
