[Postoperative recurrences of neurologic syndromes of lumbar osteochondrosis and their surgical treatment].

The authors analyse the clinical forms of recurrent neurological syndromes of lumbar osteochondrosis which developed in 6.2% of the patients operated on through a posterior approach. The recurrence of the process was caused by a progressive degenerative-dystrophic process in an earlier operated on intervertebral disc in 40 (50%) patients, a pathological condition of an intervertebral disc adjacent to one which had been operated on in 29 (36.25%), and by a cicatricial-adhesive process in the region of a previous operation in 11 (13.75%) patients. The neurological disorders were represented by radicular syndromes in 70 (87.5%) patients, radiculomyeloischemia in 8 (10%), and the syndrome of cauda equina compression in 2 (2.5%) patients. A total of 86 repeated operations were performed on 80 patients, 83 of them through a posterior approach. Repeated decompression operations produced excellent and good results in 70.1% of the patients.
