Intertrochanteric osteotomy gives compensatory correction for the severely slipped upper femoral epiphysis without endangering its blood supply. The results of thirty-five such osteotomies carried out over an eighteen-year period are reviewed. The indication for operation was a chronic slip of a third or more of the growth plate in the lateral radiograph. The mean age at operation was fourteen years and the mean follow-up period seven and a half years. The results showed that even a moderate correction of deformity as shown by the radiograph could produce a hip with a functionally satisfactory range of movement. Chondrolysis was the most serious complication and occurred in four hips. The radiological results are discussed in relation to details of operative technique and also to long-term prognosis.

There are 3 common types of spondylolisthesis: dysplastic; isthmic; degenerative. This classification, presented anew in an article published in this volume, evolved from a discussion by the members of the International Society for the Study of the Lumbar spine. The surgical treatment is designed to correct a combination of symptomatic and mechanical abnormalities characteristic of each type.

A working classification of spondylolysis and spondylolisthesis which encompasses the salient features of the disorder, has been presented. It is based on both etiological and anatomical factors.

A clinical study has been made of forty-three patients with symptoms arising from degenerative spondylolisthesis of the lumbar spine. Attention is drawn to the lower average level of the iliac crests in these patients, and to the high incidence of osteoarthritis of the hips. Many patients in this series had been referred specifically for operation and fourteen were so treated. The techniques of decompression and of spinal fusion are discussed. It is concluded that patients with back pain predominant are well treated by corsetry, only a minority needing fusion, and that patients with nerve root involvement or with symptoms of spinal stenosis need decompression. The place of spinal fusion is the main problem, but it seems reasonable, firstly, in younger patients with clear evidence of instability and degenerative change at a single level, and secondly, when radical decompression is judged to increase the risk of instability.

There are three factors which determine the volume of the spinal canal, its lateral recesses and the intervertebral canals; the developmental size; the level cephalad and caudad of the vertebral column; the multiple acquired conditions which may cause encroachment. The causes of narrowing in spondylolisthesis are characteristic of each type. Three common groups are mentioned, congenital, isthmic and degenerative and the nature of obstruction and its appropriate treatment is described in each case.
