Data Trace Editor – Discussion: – blood supply of the soleus muscle is from peroneal artery proximally and the posterior tibial artery distally; – muscle has a mixed blood supply; – vascular supply of the soleus is from popliteal, posterior tibial, & peroneal vascular pedicles to the proximal muscle, peroneal pedicles to distal lateral belly, and segmental posterior tibial … Read more
– Discussion: – use of temporary shunt has been advocated in pts w/ long ischemia times being treated with initial orthopedic stabilization prior to vascular repair A temporary arteriovenous shunt (Scribner) in the management of traumatic venous injuries of the lower extremity. Intravascular shunts in complex lower limb trauma.

– Discussion: – vascular compromise occurs in about 5-20% of children w/ supracondylar frx; – less than 1% will be complicated by compartment syndrome and the resulting sequelae of Volkmann’s contracture; – note that a median nerve palsy, may mask a pending compartment syndrome (because there … Read more
– Discussion: – pelvic fracture menu / arterial anatomy of lower limbs – massive retroperitoneal hemorrhage may result from bony fragments and lacerated blood vessels, leading to coagulopathy and exsanguination; – associated injuries: – up to 40% of pts who have a pelvic fracture will … Read more
– See: – Vascular Trauma Associated w/ Fractures (main dissucssion); – Technique of Microanatomosis: – Discusion: – anterior tibial artery occlusion: – most common site of vascular injury; – occlusion occurs as anterior tibial artery passes … Read more
– See: Blood Supply to the Wrist: – Discussion: – scaphoid receives majority of its blood supply via dorsal vessels at or just distal to waist area; – these vessels perfuse the proximal pole in a retrograde fashion; – most important vascular branches of … Read more
– Discussion: – limited peripheral blood supply originates predominantly from the lateral and medial geniculate arteries (both inferior and superior) – these supply the meniscus through a vascular synovial covering of anterior and posterior horn attachments; – branches from these vessels arborize to … Read more
– See: – Valgus Stress Test: – Lateral Collateral Ligament: – Torn Collateral Tested in Flexion: – when tested in flexion which relaxes posterior capsule, same ligamentous laxity will result in a much greater degree of instability; – at 30 deg flexion, the cruciates are in … Read more
– Discussion: (see vancomycin and addition of antibiotics to cement, vanc in ca sulfate and local delivery of antibiotics to infected joints): – dosing: – as much as 4 gm of vancomycin (as well as 4.6 gm of tobramycin) can be used per batch of cement; – note that the cost for a 1 … Read more
