– Discussion: – anterior SI ligaments are stretched; – radiographs show slight (< 2 cm) widening of the pubic symphysis and often imperceptable widening of the SI joint; – results from low energy forces Surgeon Variability in the Treatment of Pelvic Ring Injuries Stress radiograph to detect true extent of … Read more
– Discussion: – anterior wall frx involve central portion of anterior column & involves iliopectineal line is involved; – associated injury: anterior hip dislocation; – Technique of Fixation: – anterior wall fractures are approached thru Ilioinguinal Approach w/ supine positioning; – traction removes femoral head from the … Read more
– Seee: Anterior Pelvic Injuries – Discussion: – symphyseal diastasis and/or longitudinal rami fractures; – these injuries result from relatively anterior or posterior forces applied to the anterior or posterior superior iliac spine areas; – this gives rise to forces that tend to disrupt anterior pelvis, either by fracturing … Read more
– Two Hole Implants: – two hole plate, usually a 4.5 mm, is fixed to the superior surface of the symphysis with two 6.5 mm cancellous screws immediately adjacent to the symphysis pubis; – screws are inserted on the anterosuperior surface of the pubis on either side of the symphysis … Read more
– Discussion: – anterior injury may be through symphysis or thru pubic rami unilaterally or bilaterally; – symphysis disruption may also occur with pubic rami fractures; – posterior injury: degree of SI joint disruption depends on the energy sustained during the trauma; … Read more
– See: Anterior Plate Fixation Methods – Indications: – open book pelvis injury w/ greater than a 2.5 cm pubic diastasis; – note that fixation of pubic rami fractures can be much more complex than the fixation of a simple diastasis; – controversies: – posterior injury and need for … Read more
– See: Classification and Column Theory – Discussion: – anterior column extends from symphysis pubis & obturator foramen thru acetabulum to ASIS and up through iliac crest; – anterior column is less frequently fractured than posterior column due to frequency of posteriorly directed forces; – frxs of the anterior … Read more
for severe systemic fungal infections; dose: 0.25mg/kg IV over 6hrs initially (infusion .1mg/ml); gradually increase dose as tolerated up to 1-1.5mg/kg/24hrIV over 6hr; note hypersensitivity, caution with nephrotoxic/antineoplastic agents; monitor blood, liver, and renal function, discontinue therapy if BUN >40mg/dl, Creatinine >3.0mg/dl, or if liver function test abnormalities are noted; should be delivered via Central … 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
