– positioning and prepping – posterolateral skin incision – incise thru iliotibial band – split gluteus maximus – peel back the trochanteric bursa: – divide trochanteric bursa and sweep it posteriorly to expose vastus lateralis, short external rotators and posterior border of gluteus medius; … Read more
– Discussion: – easiest method to measure leg lengths is the measure the distance from the ASIS and a marked point on the knee; – measurement is made using the cautery cord; – the thigh must be in the exact same position each time the length is measured; – steinman pin method: – separate posterior … Read more

– See: Total Hip Replacement Menu: – IntraOperative Frx: – frx may occurr early while the attempt to dislocate hip is made; – most postoperative femoral fractures can be prevented by avoiding injury to the bone during the original THR procedure; – bone lysis from secondary aseptic loosening may significantly compromise strength of the femur … Read more
– Patient Position: – ensure that patient has not rotated anteriorly, for this may allow acetabular component to be placed in retroverted position; – ensure that patient’s torso is not tilted inferiorly (as can occur from a bean bag), as this can cause reaming in an excessive … Read more
