– Discussion: – embolization in pts who have sustained vascular injures from pelvic frx is the most direct means for controling of hemorrhage; – when bleeding originates from major arteries only effective technique is direct approach to the vessels; – embolization avoids the retroperitoneal contamination that … Read more

– Discussion: – ratio between perpendicular distance from lower articular margin of patella to tibial plateau (A) and the length of articular surface of patella (B) (use lateral view w/ knee in at least 30 deg of flexion); – AB ratio in 171 normal knees was 0.80 w/ no gender diff; … Read more
Discussion in those cases in which inadequate bone remains, salvage of ankle joint may be brought about by realignment of tibiotalar joint & fusion of subtalar joint or by tibiocalcaneal fusion w/ tricortical bone graft. this fusion has been used to salvage cases of avascular collapse w/ degenerative changes in the ankle and subtalar joint; … Read more
