[Ventral derotation spondylodesis. Results of treatment of cases of idiopathic lumbar scoliosis (author's (author's transl)].

Of nearly 300 VDS operations, performed at the German Scoliosis Center, the first 50 cases have been analysed. Their follow-up was conducted over a period of two years minimally. Patients with lumbar scoliosis and double major curves will be analysed in detail separately. In suitable cases use of the ventral derotation spondylodesis offers considerable advantages as compared to other methods. Bending tests are decisive for determining the fusion area. Rotation and obliquity of the third or fourth lumbar vertebra are of critical importance. The author considers the Harrington operation no longer justified in those cases in which ventral derotation spondylodesis can be successfully used. Furthermore, the Dwyer procedure has to be considered obsolete.

[Osteoporosis and halo traction in scoliosis patients (author's transl)].

In 54 patients who underwent halo traction for an average of 80 days each, there was no laboratory evidence of any change in calcium metabolism. Histologically, there were slight but significant bony changes after termination of halo traction treatment, principally "low-turnover" osteoporosis, which was possibly more prevalent in female patients. Where a slight osteoporosis already existed prior to halo traction, it generally became more severe. The study seems to show that no relationship exists between the etiology of scolioses and the development of osteoporosis. It proves that in respect of the development of osteoporosis also, permanent halo traction is not a neutral procedure.

[First results of the Luque operation (author's transl)].

The first 12 patients operated according to the method of Luque (segmental spinal wiring) at the German Scoliosis Center, have been subject to a preliminary assessment. Results of the Luque operation are superior to those of other procedures in specially selected cases. Most important advantage of the Luque operation is the instant post operative stability. For this reason the procedure for operating deformities of the spinal column in cases of neuromuscular diseases and collapsing spine of paraplegic patients is especially advisable. Dangers and risks of this novel technic are pointed out.

[Corrective surgery for kyphosis in bekhterev's disease - indication, technique, results (author's transl)].

14 patients suffering from Bechterew's disease with a marked kyphotic deformity of their spine have been subject to extension osteotomy. Follow-up of 12 patients ranges from 7 to 33 months. Results have been good in 10 and satisfactory in 2 cases. Increase in body length has been between 2 to maximally 26 cm. Surgical procedure, results and complications have been demonstrated. Possibility of early spondylodesis in Bechterew's disease for elimination of pain and avoidance of progressing deformity is discussed.

[Surgical treatment of unstable, therapy-resistant and painful lumbosacral joints by distracting decompressive posterolateral spondylodesis over the divided sacral bar according to Zielke's method (author's transl)].

Here the procedure of the distracting decompressive fusion over the divided sacral bar which Zielke developed 8 years ago is being described. This procedure was applied in over 150 cases. In a follow-up only one pseudarthrosis was found in the area of L5/S1. 70% of the previously pensioned patients could at least be partially rehabilitated. 32 patients were asked of their opinion with a questionnaire. Only 2 patients (6%) assessed the operation results with "bad". Indication is in all instabilities of the lumbosacral joint. The problem of the multi-operated back can be largely solved through the possibilities of this procedure.
