– Discussion of Open Femur Frx: (see open frx menu) – see: gun shot wounds – rates of wound infection should be < 4 % w/ meticulous debridement of wound; – rates of union and the functional results have been comparable with those obtained after nailing of closed fractures; – compartment … Read more
– Discussion: – fracture types: open tibia fractures, open fractures of femur – treat all open fractures as an emergency; – perform thorough initial eval to dx other life-threatening injuries: (see trauma management); – open joint injuries – gun shot wounds – controversies: non operative treatment: – Nonoperative … Read more
– Discussion: – artery arises from the internal iliac artery in the pelvis; – in the pelvis, it sends a branch to the obturator internus muscle; – as vessels emerge from obturator canal, they divide into anterior and posterior branches that, instead of continuing down thigh, circle … Read more
Origin: the margin of bone immediately around the medial side of the obturator foramen, from the rami of the pubis and the inferior ramus of the ischium; Insertion: posterior aspect of the greater trochanter; Action: External Rotation of femur at the hip; (see external rotators) Synergists: Periformis, Gemellus Superior, Gemellus Inferior, Obturator … Read more
– See: External Hip Rotators; – Anatomy: – origin: inferior medial surface of the obturator foramen and the quadrilateral surface; – insertion: after passing thru the lesser sciatic notch, it inserts on the superior posterior aspect of the greater trochanter of the femur; – action: outward rotation of the … Read more
– See: – Epiphyseal Artery – Metaphyseal Artery – Periosteal Artery – Discussion: – nutrient artery enters into the diaphysis of long bones through an oblique canal; – direction of canal is determined by relative amount of growth that has occurred at … Read more
– Discussion: – abnormally narrow intercondylar notches have been shown to correlate directly with an increased incidence of ACL tears; – w/ excessive internal rotation of the femur, the ACL may be ruptured as it impinges on the edge of the intercondylar notch; – notchplasty is used to widen the anterior portion and recess of the … Read more
– Discussion: – also known as fibrous cortical defect; – most common bone lesion (40% children); – it results from defect of periosteal cortical bone development which leads to failure of ossification; – natural history: – lesion typically develops in childhood … Read more
– Discussion: – few indications, except in elderly and osteoporotic patients w/ low energy extra-articular fractures; – these fractures have a high rate of hardware failure w/ operative treatment; – unfortunately, non operative treatment in elderly patients can also be associated w/ a … Read more
– Total Femoral Replacement: – indications: reconstruction following tumor resection – technique: – lateral position on a bean bag – begin proximally with a posterior approach to the hip – divide fascia laterally over femur and continue proximally to … Read more
