[Mono- and polyradicular syndromes in lumbar osteochondrosis].

The authors studied the clinical picture of lumbar osteochondritis in 1,020 patients, 151 of whom were operated on. The monoradicular syndrome was diagnosed in 68%, the biradicular (involvement of two radicles) in 27%, and the polyradicular (involvement of three and more radicles) in 7% of the patients. In the authors' opinion, the development of the mono- or polyradicular syndromes in lumbar osteochondritis depends on the character of the disc hernia (lateral, paramedian, median) and on the degree of the reactive inflammatory changes in the radicles, the epidural tissue and the spinal meninges.
