– Discussion: – anesthesia: insist on general anesthesia rather than regional anesthesia for the following reasons: – it is essential that the patient not move during delicate portions of the case; – it is often helpful to paralyze the patient during the fracture … Read more
Origin: anterior of pubis in angle between crest and symphysis; Insertion: middle 1/3 of medial lip of linea aspera; Action: addducts thigh at the hip, lateral rotation as it adducts the thigh. Some assistance in hip flexion; Nerve Supply: Obturator, L3, L2, L4; (See Innervation) Synergists: Gracilis, Adductor Magnus, Pectineus, Adductor Brevis Surgical Management of Sportsman’s Hernia in Professional … Read more
– origin: – posterior fibers: ischial tuberosity; – anterior fibers: ramus of ischium and pubis; – insertion: – from a line extending from the greater trochanter along linea aspera, medial suprcondylar line and adductor tubercle on medial condyle of femur; – action: – … Read more
(see also: Pseudoachondroplasia) Discussion autosomal dominant disorder; arises due to a point mutation for the gene encoding a fibroblast growth factor (Fibroblast growth factor receptor 3) over 80% of all persons with this disorder are born to parents who are not achondroplastic, & such parents rarely have second achondroplastic child; it is presumed in these … Read more
– Normal Hip Development: (limb development and pediatric anteversion); – at 4 to 6 gestational weeks, the hip joint develops from the cartilaginous anlage; – by 7 weeks a cleft develops between precartilagenous cells which are programmed to form the femoral head and acetabulum; – by 11 weeks, the hip … Read more
– Technique Considerations: – following restoration of fracture anatomy, contour 1/3 tubular, 3.5 pelvic reconstruction, or 3.5 DCPs, to fit medial and lateral aspect of distal humerus; – the strongest bone lies along medial and lateral columns and therefore the plate screws should be placed here rather than central portion of distal end of the … Read more

Discussion note whether the acetabular component is same size or 1-2 mm > reamers; it is essential to obtain a tight metal to bone fit at the time of surgery, inorder to avoid subsequent loosening; the surgeon should not expect that residual metal – bone gaps will fill in w/ bone; it has also been … Read more
(see also: Bone Grafting for Acetabular Defects) Discussion it is probably the result of remodeling of weak, medial acetabular bone after multiple, recurring stress fractures. intrapelvic protrussion of the acetabulum may be primary or secondary; protrusio acetabuli is not found only in inflammatory arthritides; most cases are in patients with osteoarthritis. primary protrusio: Otto Pelvis … Read more
(see also: acetabular component) Discussion it is essential to have optimal acetabular exposure; once acetabular exposure is achieved, then note native acetabular anteversion; Exposure for hips w/ severe osteoarthritis (or w/ heavily scarred hips) it may be necessary to fully release the quadratus femoris, and a portion of the gluteal sling; because the majority of … Read more
