Posterior spinal fusion in scoliosis: computer-assisted tomography and biomechanics of the fusion mass.

Thirty patients who had posterior vertebral fusion for scoliosis, performed without metallic implants, were examined using computer-assisted tomography to study the configuration of the evolving fusion mass. It was observed that the deposition of bone followed lines of force, according to Wolff's Law. The greatest amounts of bone at the apex of the curve on the concave side indicate that flexion-compression forces are greater at this point. Further, it was observed that usually the fusion mass, seen in section, has a hollow "box-section" shape, which means that a resorption of unstressed central bone occurs. The hypothesis that the torsional forces are the predominant forces acting on the scoliotic spine can explain the characteristic "box-section" of the CT scans obtained.

Adolescent

Short-term effects of an educational program for drinking drivers.

In a study of persons convicted of driving while intoxicated, mean scores on two measures of alcohol impairment decreased in subjects who completed an educational safe driving program and in those did not, suggesting a need for new approaches to DWI problems.

Alcohol Drinking

Secondary prevention of alcoholism using a population of offenders arrested for driving while intoxicated.

The paper describes a comprehensive and objective evaluation of 2358 persons arrested in Philadelphia for driving while intoxicated. It was demonstrated that 63.8% of this population was involved with alcohol to an extent that a diagnosis of alcoholism was evident, and it is suggested that these persons are in need of intensive treatment to prevent further dependency on alcohol. It is significant that these persons were diagnosed as suffering from alcoholism because they had been arrested for DWI and referred for evaluation. They are considered to offer an excellent opportunity for early intervention of what might be a progressive disease process. The study utilizes four parameters on which a diagnosis of serious alcohol impairment is established. They are the blood alcohol concentration at the time of arrest, the quantity and frequency of alcohol intake, the behavior associated with the drinking, and the Eysenck Personality Inventory, which measures the degree of neuroticism found in these subjects. Problems in the establishment of a diagnosis of alcoholism in this particular population are presented, and the need for measurement with several instruments is emphasized. Through use of the techniques described, it is possible that specific treatment directions can be established based on particular patterns of alcoholism.
