The aim of this study was to determine (1) if internal fixation was associated with a high amputation rate in patients with femur fracture and vascular injury; and (2) if patients who underwent internal fixation before vascular repair had a higher amputation rate. ⋯ In these patients, poor outcome is associated with severe leg injury, (with a Mangled Extremity Severity Score of > or = 6). Internal fixation can be safely used, and skeletal stabilization can be safely performed before vascular repair. If ischemic time is prolonged, vascular shunts should be used until skeletal stabilization is completed.

Multicenter Study Comparative Study
Improved predictions from a severity characterization of trauma (ASCOT) over Trauma and Injury Severity Score (TRISS): results of an independent evaluation.
In 1986, data from 25,000 major trauma outcome study patients were used to relate Trauma and Injury Severity Score (TRISS) values to survival probability. The resulting norms have been widely used. Motivated by TRISS limitations, A Severity Characterization of Trauma (ASCOT) was introduced in 1990. The objective of this study was to evaluate and compare TRISS and ASCOT probability predictions using carefully collected and independently reviewed data not used in the development of those norms. ⋯ In this age of health care decisions influenced by outcome evaluations, ASCOT's more precise description of anatomic injury and its improved calibration with actual outcomes argue for its adoption as the standard method for outcome prediction.

Multicenter Study
Status of nonoperative management of blunt hepatic injuries in 1995: a multicenter experience with 404 patients.
Nonoperative management is presently considered the treatment modality of choice in over 50% of adult patients sustaining blunt hepatic trauma who meet inclusion criteria. A multicenter study was retrospectively undertaken to assess whether the combined experiences at level I trauma centers could validate the currently reported high success rate, low morbidity, and virtually nonexistent mortality associated with this approach. Thirteen level I trauma centers accrued 404 adult patients sustaining blunt hepatic injuries managed nonoperatively over the last 5 years. ⋯ Bleeding complications are infrequently encountered (3.5%) and can often be managed nonoperatively. Although grades IV and V injuries composed 14% of the series, they represented 66.6% of the patients requiring operative intervention and thus merit constant re-evaluation and close observation in critical care units. The optimal time for follow-up computerized axial tomography scanning seems to be within 7 to 10 days after injury.

Medial dissection of the aorta after blunt trauma is a rare occurrence. We report the case of a 79-year-old woman injured in a motor vehicle crash who suffered an acute DeBakey type I aortic dissection.

Blunt abdominal trauma resulting in a laceration of the abdominal aorta is extremely rare. Only one previous example of this injury has been reported in a child. We present the clinical course and surgical management of blunt disruption of the infrarenal aorta in a 13-year-old boy with a subsequent delayed rupture of a third aortic laceration. This is the youngest patient to die from this type of injury after blunt abdominal trauma.
