See: – Thompson is especially suitable for the middle third of the radius, however, it is not suitable for distal third radial frxs because the posterolateral application of the plate may interfere w/ outcropping tendons to thumb, disturbing function; – care is taken with this approach to avoid injury to the radial nerve and therefore … Read more
– See: – Arteries of the Upper Limb; – Profunda Brachi; – Anatomy: – brachial artery originates at the lateral border of teres major muscle & courses down anterior humerus posterior to bicipital aponeurosis; – brachial artery has three main braches, of which profunda brachi … Read more
Discussion for detection of AVN, technetium-99 methylene-diphosphonate bone-scanning is a useful technique; bone-scanning may be less sensitive in the detection of AVN at early stage of the disease or when both hips are involved symmetrically; reactive of bone at the edge of the infarcted segment will show an increased uptake of the isotope on the … Read more
– 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: – blood is supplied to vertebral column by way of segmental arteries that arise near it from the aorta, or from adjacent arteries in areas beyond the extent of the aorta; – costocervical & intercostal arteries in thorax; lumbar and iliolumbar arteries in lumbar region; and lateral sacral … Read more
– Discussion: – problem with standard BKA, the stump is often bulky and there are delays with patellar tendon prosthesis; – when healed the scar crosses the prominent crest of the tibia, which is often the point that broke down with prosthetic use; – note that the BKA prosthesis … Read more
– See: Prosthetic Feet: – PTB sockets: – provide some weight bearing support in the area of patella tendon and medial tibial flare; – BKA Suspension: – important design considerations for both sockets include – support (pressure distribution) – control (based … Read more
