Data Trace Editor – See: – Anteromedial Instability – Anterolateral Instability – external rotation – Discussion: – internal-rotation laxity increases w/ knee flexion, w/ largest amount (25 degrees) seen in the 20 to 40-degree range of knee flexion; – of all of structures around the knee, only MCL and ACL play an important role in the … Read more
– Discussion: – Delivers a preset tidal volume at preset rate – Remainder of patient’s minute ventilation is self generated and is independent of the ventilator; – IMV rate is initally set at the same respiratory rate as the assist control mode and is slowly reduced if the arterial blood gas levels (particularly the PaCO2 … Read more
– Discussion: – consistent relationship between cerebral blood flow and intracranial pressure is difficult to demonstrate until levels of 40-50 mm Hg are reached; – well-engineered intracranial-pressure transducers can easily be inserted by the neurosurgeon in the emergency room; – use subdural rather than an intraventricular placement (which could reduce intracranial pressure … Read more
– Discussion: – condyles will frx apart w/ variable amount of displacement, & comminution; – Approach: – use posterior approach w/ olecranon osteotomy; – articular surface is restored using interfragmentary lag screw fixation; – coronoid and olecranon fossa must not be violated with fixation, nor should width … Read more
– Discussion: – one of most common knee injuries in children; – most common in children between ages of 8-14 yrs; – usually result from avulsions of anterior intercondylar eminence from pull of ACL; – fragment of tibial spine may be non displaced, or … Read more

– Discussion: – when needle is inserted into muscle or moved w/in muscle, there is a single burst of activity that usually lasts 300 to 500 ms; – activity is related to movement of electrode and is thought to result from mechanical stimulation or injury of the muscle fibers; – Increased Insertional Activity: … Read more
