Pelvic Trauma Pelvic fractures represent approximately 3 percent of skeletal injuries. Overall mortality from pelvic fractures ranges from 5 to 16 percent, with the rate for unstable pelvic fractures approximately 8 percent. The mortality rate associated with acetabular fractures is 3 percent, while open pelvic fractures, which comprise 2 to 4 percent of all pelvic fractures, are associated with a mortality rate of up to 45 percent. Most fatalities stem from associated internal injuries; deaths attributed solely to pelvic fractures range from 0. 4 to 0. 8 percent of trauma fatalities. Patients aged greater than 65 with pelvic fractures have a mortality rate of approximately 20 percent. Overall, pelvic fractures are associated with an increased risk of death among trauma patients

Pelvic Injuries They include pelvic ring fractures, acetabular fractures, and avulsion injuries. The majority of pelvis injuries are due to high energy blunt trauma, although frail and elderly patients may sustain such injuries from a low energy mechanism, i. e. a fall.

Congenital Hip Dislocation If a congenitally dislocated hip is flexed and abducted and externally rotated, the femoral head slips over the acetabular rim, reducing the dislocation and producing a palpable and/or audible click or jerk. This is called the Ortolani click.

Slipped Capital Femoral Epiphysis The child with SCFE usually presents with pain and a limp. Since the pain is often located only in the thigh or knee, the diagnosis is often missed. It is important to remember that knee pain in the child can be secondary to hip disease.

Slipped Capital Femoral Epiphysis On physical examination, there is frequently limitation of motion, especially internal rotation and abduction. As the examiner flexes the hip, it moves into external rotation and the patient often holds the leg externally rotated when standing.

Slipped Capital Femoral Epiphysis Tests: X-ray A/P and Lat views Femoral head is displaced posteriorly and inferiorly in relation to femoral neck Determine whether Klein Line is present—on A/P view, a line drawn along superior border of femoral neck should pass through a portion of the femoral head; if not, SCFE is diagnosed Treatment: Surgery with internal fixation Prognosis of osteoarthritis if it is not recognized and treated

Avascular Necrosis Most commonly involves the femoral head. It is usually caused by trauma, typically occurring after a displaced femoral neck fracture and less frequently after a fracture-dislocation of the hip. Necrosis results when the vascular supply to the femoral head is disrupted at the time of injury. Non-traumatic AVN occurs in a younger population and is commonly bilateral. Corticosteroid use can result in AV Even one dose!!!
