The authors review the fundamental scientific factors that govern the healing of bone and conclude that they form a physiologic basis for the preferred use of external fixation in the management of fractures of the long bones as well as in the management of leg lengthening.
Retrospective studies were carried out on 314 patients who underwent oil-based or water-soluble myelography between July 1981 and July 1982 in two community hospitals. Morbidities and efficacies were compared and it was concluded that metrizamide myelography is a preferable method.
This is a report of long-term results and complications in 62 patients. Closed tibial osteotomy, direct tibial distraction, and simultaneous indirect proximal fibular epiphyseal distraction are the essential features of this new technique. Fibular osteotomy and complications from tibiofibular synostosis are eliminated. Bone graft and plating procedures have been proven to be unnecessary. The patient is ambulated immediately. Hospitalization has been reduced to a few days.

An external fixation device has been designed for rigid fixation of fragments of bone. It can be used in operations to lengthen the tibia and can be adapted to the compression fixation of fractures. This paper describes the apparatus and its use in the treatment of 10 complicated fractures.
The effect of medical sympathetic blockage with reserpine was studied in 48 rats following crushing of the cord. Control experiments were carried out with reserpined and unreserpined groups. Marked sensory-motor improvement was found in the reserpined group.
Cobb in 1950 stated that a high proportion of scolioses, classified as idiopathic, may be due to neurofibromatosis. This paper describes a retrospective study of a series of 3209 scoliosis cases to determine the incidence of neurofibromatosis. It was found to be just over 3 per cent. Two different clinical pictures of scoliosis were seen among the neurofibromatosis cases.
Using a new type of external fixation device for lengthening the tibia, lengthenings of from 3.5 to 6.5 centimeters were accomplished in thirty-two children, eight to seventeen years old, the six complications, none of which jeopardized the result. The procedure was painless and the patients were ambulatory on crutches two to three days after operation, while lengthening was continued as an out-patient procedure.
A new type of external fixator bas been designed for absolute fixation and prevention of lateral migration of fragments of bone. The apparatus has been used for leg lengthening. The apparatus and the technique are described and results of the first 24 cases are presented. Complications were minimal. The technique proved to be simple to apply, and painless to the patient with his ambulation from the start. And less expense are involved because of a very short period of hospitalization.

Two cases of complete and permanent paraplegia following lumbar myelography using iophendylate are reported. Both patients had had syphilis many years earlier.
