[Surgery for backache].

All types of lumbar pain are of course not an indication for surgery. However, an operation may bring relief from lymbodynia in given conditions, owing to the better knowledge of spinal physiopathology and to the evolution of the surgical technique. This is the case for intervertebral disk pathology, lesions of the posterior articular structures, lumbar canal stenosis, vertebral tumors or malunions, as well as for some cases of painful frontal or sagittal deviation of the spine. State-of-the art techniques utilize arthrodesis, often with a plate or CD-material osteosynthesis, but future surgery should be aimed at preserving motion.

[Study by radioactive microspheres of bone microcirculation in aseptic osteonecrosis of the femoral head].

Thirty-two hips affected by aseptic necrosis, four of them post-traumatic and 12 contralateral hips thought to be healthy have been studied by combining superselective arteriography with the injection of radioactive microspheres. It has been possible to show that aseptic necrosis begins with a global ischaemia and is followed by an incomplete revascularisation leaving a necrotic area. On the border between the two areas hypervascularity produces a zone of fragility where microfractures develop with detachment of a sequestrum. The presumed opposite hip is almost always, even in traumatic lesions, the site of a hypovascularity which seems to suggest a predisposition to the lesion. There is a correlation between radiological and clinical worsening and the development of revascularisation in the femoral head.

[Cotrel-Dubousset instrumentation in the treatment of scoliosis].

The authors describe the operative principles of the C.D. device reviewing implantable material (rods and hooks, screws and transverse system). The principles of this surgical approach (2 rods) which offers the possible distraction and contraction where necessary, are described. Good derotation is achieved and a strong and stable square support device enabling the patient to be got out of bed rapidly without any need for post-operative support. The post-operative care is extremely easy and a rapid return to school activity is possible.
