– See quadriceps muscle; Origin: Lower 1/2 of the intertrochanteric lines, medial lip of linea aspera, upper part of medial supracondylar line, medial intermuscular septum tendons of adductor magnus and adductor longus; Insertion: Medial border of the patella by the ligamentum patella into the tibia tuberosity; Action: Extends the leg at the knee … Read more
– See: Venous Repair – Discussion: – veins accompany the arteries of the lower limb, and those that parallel the large arteries of leg are paired; – five major venous structures of leg are greater and lesser saphenous veins, posterior & anterior tibial veins, & peroneal veins; – Greater Saphenous Vein: … 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
– 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: – 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
– 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: – Medial Collateral Ligament: – Varus Stress Test: – Primary vs Secondary Restraints: – seationing of MCL results in marked valgus instability; – isolated sectioning of ACL, PCL, LCL, or posterolateral structures does not cause large increases in valgus angulation; – … Read more
