[Retrospective study of traffic accident victims: incidence after the new National Traffic Code implantation].

The authors present a study about the frequency of the injuries caused by traffic accidents on the orthopedic patients admitted to the emergency of Institute of Orthopedics and Traumatology at the Hospital das Clínicas of the School of Medicine São Paulo University, before and after the new National Traffic Code. They found a decreased number of polytraumatized patients and severe injuries after the beginning of this new legislation.

Atlanto-axial dislocation in children.

The authors present 14 cases of C1 C2 dislocations in children (8 boys and 6 girls; mean age, 6.9 years) seen at the Orthopedics and Traumatology Institute of the University Hospital, Faculty of Medicine, University of São Paulo from 1978 to 1990. In view of the disappointing results obtained by conservative treatment in 6 of the 14 patients, the authors recommend early atlanto-axial arthrodesis in cases of C1 C2 dislocation in children.

Herniation of the lumbar disk in adolescents.

The authors review eight cases of lumbar intervertebral disk herniation in adolescents aged less than 16 years, with a minimum follow-up treatment of 2 years during an 18-year period. All patients presented lower back and sciatic pain, antalgic scoliosis, and a positive Lasègue sign. Nerve compression signs were present in 25+ of the cases. Seventy-five percent of the cases underwent myelography and 25% underwent computerized axial tomography. Results were good in all cases.

Study of fracture healing in protein malnutrition.

The present study was designed to assess the effects of nutrition on fracture healing in a controlled animal model. Tibial fractures were studied in 115 Wistar rats divided into four groups: group 1,50 control animals kept on a normal diet; groups 2 and 3, 45 protein-deprived animals, and group 4, 20 animals submitted to protein malnutrition before the fracture and then placed on a normal laboratory diet. The parameters evaluated during the study were: variation in animal weight during the experiment (confirmation of protein malnutrition), fracture healing as determined by bone callus radiology, macroscopic evaluation of bone callus mechanical resistance, and histological fracture examination by common light microscopy after staining with hematoxylin-eosin. The results showed the beneficial effects of protein nutrition support on the healing of lone bone fractures. Callus formation was significantly improved in groups 1 and 4 compared to groups 2 and 3. In groups 1 and 4, callus development was normal, with regular bone tissue formation, whereas in groups 2 and 3 there was a large amount of fibrous-connective tissue with scarce formation of osseous tissue.

[Effect of electromagnetic fields on osteogenesis: an experimental study on rats].

The authors studied experimentally the electromagnetic pulsing field effects in an experimental model in rats, for evaluation of the velocity of consolidation of tibial and fibular fractures. The animals were followed for a period of three weeks under continuous stimulation and there were done radiological evaluation weekly and histological study at the end of the study. There were no histological, clinical or radiological differences between the group of rats submitted to electromagnetic pulsing fields and the control group.

Evaluation of the physical fitness by the Bruno Balke protocol in sedentary and wheelchair trained paraplegic patients.

The Bruno Balke test is one of the methods available to measure the oxygen intake in wheelchair users. The equation of the test is:intake O2 = 33+ (speed average-133) x 0.17 ml/kg x min. (-1). The average speed represents the acceleration and may be used to measure the level of physical fitness. In order to verify the efficiency of this kind of evaluation, we selected ten male, sedentary paraplegic patients, level D5-D12 in an ordinary rehabilitation program and ten paraplegic athletes. All of them were submitted to the Bruno Balke test. The results demonstrated that the average speed, the covered distance and the oxygen intake were significantly greater in athletes than in sedentary individuals.

[Surgical treatment of idiopathic scoliosis in adolescents by the Harrington method].

Forty six patients with idiopathic scoliosis were treated according the Harrington method. The surgical treatment was done with the Harrington distraction rod, and vertebral arthrodesis with autogenous iliac bone graft. The patients wore a Risser-Cotrel body-cast for nine months but started walking two days after casting. Good clinical results were obtained in all the patients. Final curve correction was 40%. In this series of patients no pseudoarthrosis occurred.

[Complications of herniated disk surgery].

The author studies the complications that can occur in the lumbar spine operations particularly in the disc protrusion surgeries. The pre, intra and post-operative complications as well as the early and late complications were analysed. The factors that may lead to bad surgical results are discussed.

[Traumatic spondylolysis].

The authors present the results of treatment of seven cases of spondylolysis with a two years follow up. Six patients were treated with the thoracolumbosacral orthosis and one with L5-S1 fusion. At the end of the follow up all patients were pain free.

[Spinal cord injuries in children].

Spinal cord injuries are rare in children, in face of their higher mobility comparing to adults. The high cervical and the thoracic segments of the spine are more frequently affected. In the last 10 years we had 90 cases of spinal injuries in our service being 12 with neurologic deficient (8 male and 4 female) and four of them without radiographic abnormality, even in the dynamics studies. The authors emphasise the possibility of occurrence of neurologic deficit in children after trauma, even without any radiographic abnormality.
