Discussion anatomic axis of femur is approx 6 deg of valgus from mechanical axis or 9 deg of valgus from vertical axis w/ variations according to body habitus; anatomic axis of tibia is in approx 2-3 deg of varus from mechanical axis; lines that intersect the tibia and the femur intersect at knee; this angle averages 6 deg
vascular supply to the humeral head Two Part Articular Segment Displacement fracture plane is through the anatomic (not surgical neck); anatomic neck represents the old eiphyseal plate; surgical neck represents the weakened area below the tuberosities and head approximately 2 cm distal to the anatomic neck; significant chondral defects and minimally separated fragments may go … Read more
