Pulmonary artery and pulmonary wedge pressures were measured at rest and during exercise in 25 young patients with moderate to severe scoliosis. Simultaneous determinations of arterial blood gases and pH were performed. The results of the vascular pressure measurements were compared with those obtained in 15 healthy young subjects. In all patients the pulmonary artery and pulmonary wedge pressure were normal at rest. During mild ergometer exercise, however, an abnormal rise in pulmonary artery pressure occurred in 9 patients. Moreover, an increased diastolic pressure gradient across the pulmonary vascular bed was found in some scoliotic patients indicating an elevated pulmonary vascular resistance. It is supposed that this haemodynamic abnormality is primarily due to a restriction of the pulmonary vascular bed. Relationships between pulmonary artery pressure and arterial oxygen tension and blood pH, respectively, could be found. The possible significance of these results is discussed.

Scoliosis in fish is caused by several diverse agents that possibly act on the central nervous system, neuromuscular junctions, or ionic metabolism. The organochlorine pesticide Kepone induces scoliosis in the sheepshead minnow. Some effects associated with Kepone-induced scoliosis in these fish are disruption of myotomal patterns, inter- and intramuscular hemorrhage, fractured centra of vertebrae, and death. The histological syndrome of Kepone poisoning in fish and the clinical syndrome in humans suggest that the nervous system is a primary target for Kepone and that scoliosis is a secondary effect of Kepone poisoning in fish.

Oesophagitis developed in 4 patients, 3 of whom had scoliosis braces and 1 a body cast after surgery for kyphoscoliosis. Symptoms varied from chronic epigastric pain to gastrointestinal haemorrhage. Prophylaxis of oesophageal disease in children undergoing correction of scoliosis may prevent severe oesophagitis.

Two brothers with oligosymptomatic mucopolysaccharidosis VII were observed from age 11 8/12 to 16 years, and 15 1/2 to 19 years, respectively. Asymptomatic thoracic kyphosis and mild scoliosis were the prominent clinical features. Herniae, hepatosplenomegaly, corneal clouding and shortness of stature were absent. Both had Alder type granulations in polymorphonuclear leukocytes and to a lesser degree in monocytes. Ultrastructural analysis of blood leukocytes revealed polymorphous inclusions of probably more than one class of organic substances. Radiological signs were mild, confined to the spine and consisted of irregularities of upper and lower vertebral plates, of vertebral flattening and some osteophytic changes. Both patients excreted excessive amounts of acid mucopolysaccharides in urine and also globoside. Cultured skin fibroblasts of both patients contained metachromatic granules, had only approx. 10% of normal beta-glucuronidase activity and degraded sulfated mucopolysaccharides at a slower than normal rate. Sera of the patients had none or minimal beta-glucuronidase activity, the mother's serum had subnormal and the father's serum low-normal activity. The older brother is the oldest known case of mucopolysaccharidosis VII. As this hereditary disorder may take a remarkably mild clinical course, beta-glucuronidase-deficient juveniles may exist undetected in the general population.

The natural history, associated anomalies, and response to operative and nonoperative treatment were reviewed in 102 patients with neurofibromatosis and spine deformity. Eighty patients were found to have curvatures associated with dystrophic changes in the vertebrae and ribs. The presence of dystrophic changes such as rib penciling, spindling of the transverse processes, vertebral scalloping, severe apical vertebral rotation, foraminal enlargement, and adjacent soft-tissue neurofibromas was found to be highly significant in prognosis and management. Brace treatment of dystrophic curves was unsuccessful. Posterior fusion, with or without internal fixation, was the procedure of choice for problems due purely to scoliosis. Patients with dystrophic kyphoscoliosis required both anterior and posterior fusion to achieve stability. Sixteen patients had compression of the spinal cord or cauda equina.

Fifty-six patients with neurofibromatosis were examined for abnormalities of the cervical spine and seventeen of them had demonstrated lesions there. Of the thirty-four patients who had scoliosis or kyphoscoliosis, fifteen (44 per cent) had cervical lesions. Many of the patients with those lesions were asymptomatic. To avoid the complications attributable to the cervical spine, we recommend roentgenographic examination in all neurofibromatosis patients who are about to have general anesthesia or skull traction for treatment of scoliosis.

Scoliosis is frequently a progressive deformity despite the best efforts at external bracing and various exercises. In childhood, scoliosis is usually insidious and is rarely symptomatic. In later years, however, scoliosis leads to cardiopulmonary compromise, neurologic dysfunction, degenerative joint disease, and cosmetic deformities. Therefore, surgical correction is indicated in selected patients. Internal fixation with spinal fusion is more effective than fusion alone. Postoperative radiographs must be examined closely for general as well as orthopedic complications. Loss of correction and failure of hardware are signs of pseudarthrosis. Radiographic follow-up evaluation should include two views whenever possible.

A case of neurofibromatosis in a 7-year-old boy from Greenland is presented. The patient suddenly developed a severe thoracic scoliosis because of a total luxation of the upper thoracic vertebrae caused by erosion from soft tissue tumours in the region. Tomography revealed the bone changes, and CT whole-body scanning showed the extent of the soft tissue tumours and also the destruction of the vertebrae. The diagnosis was verified by biopsy.

Scoliosis is a complication of spinal lesions in neurofibromatosis, and leads frequently to major deformities with dislocations. The authors conducted a critical study of 31 cases surgically treated during the 1954-73 period of time. The techniques of spine straightening and of arthrodesis were recalled. The authors conclude that in case of moderate deformity (less than 100 degrees) Harrington's operation was satisfactory enough when correctly conducted. In case of severe dislocation and kyphosis, straightening was obtained after long lasting casts and halo tractions. Then posterior fusion using Harrington's rods had usually to be completed by anterior, transthoracic fusion for better solidity.

Most severe scoliosis and kyphoscoliosis are not unfrequent in European countries. The purpose of their treatment is not only cosmetic but, often, vital. Patients are hypotrophic and their vital capacities usually very poor. Since 1952, the authors have treated (partial, reduction and fusion) 183 patients: with curves above 100 degrees (101 degrees-203 degrees). Reduction was obtained by distraction cast or halo-traction. Surgical treatment (one or two stages) used Harrington rods and fusion with a large amount of iliac bone. These procedures are dangerous for the medullary function. Controls must be performed during the operative distraction. Follow up studies demonstrated the stability of the obtained reductions.
