Data Trace Editor – 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
– 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
– 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
– 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: – strong and well-defined, arise from antero-inferior surface of medial epicondyle and inserts at the sublimis tubercle, adjacent to the joint surface; – primary constraint to valgus instability; – in flexion, MCL provides 54% of valgus stability; … Read more

– Dx of MI – ST depression of more than 2 mm in any of the inferior leads (II, III, or aVF) 5in pts w/ anterior infarction is assoc w/ hospital mortality of > 10% compared with < 10% in anterior infarctions w/o such marked inferior ST depression.
– Bony Impingement: – pts who have persistent pain in anterior aspect of ankle & who have anterior tibiotalar spur evident on a lateral roentgenogram need additional diagnostic evaluation and management; – extreme dorsiflexion required by the demiplie position in ballet can lead to impingement of anterior lip of … Read more
