Alcohol has been shown to confound the initial assessment of trauma victims, and cocaine is associated with numerous medical and anesthetic complications. A prospective study was performed to determine the prevalence of alcohol and illicit drug use in orthopedic trauma patients at an inner-city teaching hospital. All patients admitted to the orthopedic service during a 2-year period (January 1993 to December 1994) were prospectively studied. ⋯ We conclude that drug and alcohol use is widespread in patients presenting with orthopedic injuries and we make recommendations regarding treatment of these patients. The majority of orthopedic trauma resources in this setting is devoted to treating intoxicated patients. Drug and alcohol use is a major social problem and may have an adverse effect on patient care.

Case Reports
Forearm compartment syndrome due to automated injection of computed tomography contrast material.
Automated injection of computed tomography contrast material can produce a compartment syndrome if extravasation occurs. Unconscious patients and the elderly may be at particular risk. Selection of nonionic contrast material, careful evaluation of the intravenous administration site, and close monitoring of the patient during use of a power injector may help minimize or prevent extravasation injuries.

Fifteen cadaveric adult bony hemipelvis specimens and 30 adult dry bone specimens were obtained to evaluate the configuration of the anterior column of the acetabulum and to develop a safe path for screw placement into it. Each cadaveric specimen was sectioned at 1-cm intervals, beginning at the level of the inferior border of the acetabulum (junction between the anteroinferior edge of the acetabulum and the most anterolateral edge of the superior ramus of the pubic bone). The plane of the cross-section was perpendicular to the anterior column. ⋯ At 3.0 cm superior to the inferior acetabular margin, these angles were found to be 20.7 +/- 4.3 degrees, 29.4 +/- 6.0 degrees, and 39.3 +/- 5.9 degrees, respectively. All of the above mentioned angles are with respect to the perpendicular of the longitudinal axis of the anterior column without violation of the hip joint. Screws placed 1.0 cm lateral to the pelvic brim at the levels of 1.0, 2.0, 3.0, and 4.0 cm superior to the inferior acetabular margin and directed perpendicular to the anterior column penetrated the hip joint.

Thoracolumbar burst fractures are a major cause of disability; however, there are few studies on the functional outcome of patients with this injury. The purpose of this study is to evaluate the functional outcome of patients with thoracolumbar burst fractures using a generic and a condition-specific health status survey. The SF-36 survey (generic) and the Roland scale (condition-specific) were administered to 24 patients who had a minimum of 2 years follow-up after a thoracolumbar burst fracture without neurologic deficit. ⋯ There was a strong correlation (r = 0.71) between the Roland scale and the SF-36 pain scale. There were poor correlations between the Roland scale and residual kyphosis (r = 0.003), and between the SF-36 pain scale and residual kyphosis (r = 0.10). There was no significant difference in the functional outcome of those patients treated operatively versus nonoperatively.

Malpositioning of iliosacral screws happens more often when common variations in the morphology of the upper sacral segments are unrecognized. Radiological-anatomic correlations of sacral anatomy were studied in 10 fresh-frozen cadaveric pelvises without evidence of skeletal disease, obtained from six male and four female donors. Eighty consecutive patients with complicated pelvic fractures treated operatively by the same surgeon using percutaneously placed iliosacral screws were evaluated. ⋯ On the true lateral projections, the iliac cortical density adjacent to the sacroiliac joint parallels the sacral alar slope and is almost always caudal and posterior to it; it delineates the anterior extent of the "safe zone" for iliosacral screw insertion. Thus, the lateral sacral image provides the surgeon with a better understanding of the sacral alar slope and can help prevent iliosacral screw placement errors. The lateral sacral image should always be used intraoperatively with the inlet and outlet images to guide iliosacral screw placement.
