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
– See: – Blood Supply to the Wrist – Kienbock’s Disease – Discussion: – majority of lunates have both dorsal & palmar vessels & are thus as well vascularized as the other carpal bones; – neither single intraosseous nor extraosseous disruption alone will cause avascular necrosis … Read more
– See Quads Origin: Proximal 2/3 of the anterolateral surface of the femur, lower 1/2 of the linea aspera, upper part of the lateral supracondylar line; Lateral intermuscular septum; Insertion: By tendons of the rectus and vastus muscles into the superior border of the patella and by the ligamentum patella into the … Read more
– See Quads Origin: upper part of intertrochanteric line, anterior and lower borders of greater trochanter, lateral lip of gluteal tuberosity, upper half of linea aspera, lateral intermuscular septum, and tendon of the gluteus maximus; Insertion: lateral border of the patella by the ligamentum patella into tibia tubercle; Action: extends the … 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: – 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: 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
– 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
– 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
– 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
