Adult lumbar scoliosis.

This report details the expierience with adult lumbar scoliosis among patients at a scoliosis center. Some curves are shown to progress in the adult, while others appear de novo. Pain arising in adult scoliosis may reflect root compression or segmental degeneration. Once pain arises in an adult lumbar curve, it is likely to be progressive and often requires surgical treatment.

Postoperative lumbar epiduro-arachnoiditis. Diagnostic and therapeutic aspects.

Thirty-eight patients with the diagnosis of postoperative epiduro-arachnoiditis are reported upon. All had had previous surgery for disc herniation, and the diagnosis of epiduro-arachnoiditis was confirmed at repeat surgery. Massive epidural scarring with no coexistent pathologic condition was found in every patient, and adhesive arachnoiditis was noted in three. The common clinical presentation consisted of low-back pain and sciatica, and radicular pain was usually a continuation or a recurrence of the preoperative sciatic pain. Neurologic deficits were mild, and no patients with the classic picture of adhesive arachnoiditis were found. Myelographic patterns did not disclose any correlation with the clinical symptoms. Five myelograms were normal, while six others simulated a recurrent disc herniation. The results of scar excision were good in 13 patients, fair in eight, and a failure in 17.

Treatment of lumbar disc herniation by chymopapain chemonucleolysis. A report on 120 patients.

Ninety of 120 patients with herniated lumbar discs who received an intradiscal injection of chymopapain achieved successful recovery. Sixteen of the 21 patients who underwent subsequent surgery had a good result. Study of the unsuccessful cases showed that disc sequestration and lateral stenosis were the major organic causes of failure. Certain radiologic criteria suggestive of sequestration and of important segmental stenosis are described. They appear to be a contraindication to chemonucleolysis. Psychogenic pain components and the failure of the enzyme to hydrolyse the nuclear proteoglycans in a few cases were the other two causes of poor results. A survey of postchemonucleolysis computed tomographic scans suggested that, although capable of digesting nuclear material in most cases, chymopapain may also work through an "anti-inflammatory" mechanism.

Degenerative spondylolisthesis.

Degenerative spondylolisthesis is one important type of spinal stenosis. The spinal canal stenosis varies in degree. This is the result of anterior slipping of the whole vertebra, usually L4 on L5. The clinical picture is not greatly different from that observed in the other types of lumbar canal stenosis. The surgical management involves decompression of the cauda equina by laminectomy. Often this is associated with arthrectomy to decompress the nerve roots. Extensive excision of the neural arch may result in further spinal instability for which spinal fusion is generally advisable.

[Treatment of giant cell tumors of the sacrum. Apropos of an observed case].

A case of giant cells tumor of the sacrum, invading a large part of the sacral body, the buttock is reported. The sacro-rectal space and the sacral canal with the cauda equina were compressed. Complete avulsion was performed, each nerve being closely dissected. Clinical recovery with roentgenographic aspect of bone healing is still present, three years and a half post-operatively.

[Avascular necrosis of the femoral head following fracture of the neck. Early diagnosis using radioactive tracers].

The authors have injected Sr85 intravenously and studied its fixation in samples taken from the femoral head with a trephine in the course of reduction and fixation of fractures of the femoral neck. Thirty-eight cases were studied, of which ten developed secondary avascular necrosis of the femoral head. All the patients were followed up for more than three years. The standard technique is described in detail. The authors consider that this technique was valid. All the necroses were able to be predicted. The examination of the samples took about 15 minutes during the operation. The method makes it possible to choose between internal fixation and prosthetic replacement.

[Postero-lateral bone grafting in the lumbar and lumbo-sacral spine (author's transl)].

78 arthrodeses of the lumbar and lumbo-sacral region were performed by a postero-lateral approach. The technique is described and the results. The patients were reviewed after an average follow-up of 4 years. Fusion was obtained in 83 p. 100 of cases. The operation was performed for low back pain, spondylolisthesis, or lumbar arthrosis. Indications are discussed in relation to the etiology.
