– Discussion: – frx occur as a result of a fall – from direct and indirect forces; – occurs along lines between greater and less trochanters; – theoretically extracapsular, however, it is not always possible to distinguish betwee intertroch and basilar femoral neck frx; – extracapsular intertroch frx occur thru cancellous bone, which has an … 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
– Technical Considerations: – consider debriding the wound with a separate set of surgical instruments / drapes – exposure: extend the traumatic incision longitudinally in order to fully expose zone of injury; – pressure irrigation – debridement of open tibia fractures – Arguments for Leaving Wound Open w/ Delayed Closure: … Read more
– See: tibial fracture menu and infection menu – Discussion: – by definition involves a tibia fracture infection that has gone on to non union; – by definition, infected non union is a Cierney IV osteomyelitis, meaning that the fracture is unstable before and after the debridement; – infected non union … Read more

– See: Sacral Sparing: – Definition: – complete cord injury implies unequivocal absence of motor or sensory function distal to injury in absence of spinal shock; – w/ complete injuries, an improvement of one nerve root level can be expected in 80% of patients, and approximately 20% will recover 2 … Read more

– Discussion: – see pediatric femur frx – commonest site of fracture of the femoral shaft is in its middle third, where normal anterolateral bowing of diaphysis is at its maximum; – torsional force produced by indirect violence results in a long spiral or oblique frx, whereas a transverse frx … Read more
– Technique: – at a point 3-5 cm above post. tip of greater troch., an incision is made which extends obliquely (proximally & posteriorly) for 10 cm; – for obese pts begin incision well above greater troch. (7-10 cm) & again extend proximally and posteriorly; … Read more
– See: Humeral Frx – Main Menu: / humeral shaft fractures – Discussion: – may be indicated for multi-trauma patients w/ humeral shaft frx, and patients w/ pathologic frx; – note that following humeral shaft frx, IM nailing provides torsional and bending stiffness of only 20-30% of normal; … Read more
