    Description / Table of Contents: Summary Various methods of lumbosacral fusions for the treatment of degenerative spinal diseases are used clinically. Results vary greatly depending on indication, type of fusion, implants, and method of evaluation. In a retrospective clinical and radiological examination after an average follow-up time of 3.9 years this study reports on the outcome of lumbosacral distraction spondylodesis (LSDS) in a consecutive series of 147 patients being fused for the treatment of spondylolisthesis, failed-back syndrome, or lumbar instability. LSDS consists of a posterolateral fusion together with an autologous corticocancellous H-graft wedged under distraction between the spinous processes of L4 and S1. With 81.0% good and excellent results this noninstrumented fusion technique showed the best outcome in patients with spondylolisthesis, while in cases with a failed-back syndrome or lumbar instability only 62.3% excellent to satisfying outcomes were noted. The rate of pseudarthrosis was 13.6% in the whole patient group; no major complications such as nerve root damage, postoperative neurological deficits, or spinal stenosis were found.
    Notes: Résumé Diverses méthodes de fusion lombo-sacrée sont utilisées dans le traitement des affections dégénératives rachidiennes. Les résultats sont très variables et dépendent de l'indicatio, du type de fusion, des implants et de la méthode d'évaluation. Par une analyse rétrospective clinique et radiologique après un délai postopératoire moyen de 3,9 mois, cette étude rend compte du résultat de la “spondylodèse lombo-sacrée en distraction” (LSDS) dans une série consécutive de 147 patients traités par arthrodèse pour spondylolisthésis, échec de la chirurgie lombaire ou instabilité lombaire. La LSDS consite en une greffe postéro-latérale associée à un greffon autologue cortico-spongieux en H enfoncé sous distraction entre les épineuses de L4 et de S1. Avec 81,0% de bons et excellents résultats, cette technique d'arthrodèse sans ostéosynthèse a montré ses meilleurs résultats dans le traitement des spondylolisthésis, tandis que dans les cas d'échec de la chirurgie lombaire ou d'instabilité lombaire il n'a donné que 62,3% des résultats excellents ou satisfaisants. Le taux de pseudarthroses était de 13,6% pour tout le groupe et l'on n'a pas trouvé de complications majeures comme une atteinte radiculaire, un déficit neurologique post-opératoire ou une sténose lombaire.

    Notes: Summary Planning and performing lumbar microdiscotomy—with or without a microscope—requires a three-dimensional understanding of the spinal canal and its surrounding structures. A new disc-related classification is helpful. Lumbar motion segments are divided into disc, infradiscal and supradiscal levels in the craniocaudal plane and into medial, paramedial and lateral zones in the horizontal plane. Traversing roots, with or without nerve root sheath, and exiting roots have specific locations to the levels and zones. A comparative study of conservatively and surgically treated patients showed that not only the size of the disc herniation but also the direction of migration of the extruded disc material has a bearing on the form of treatment that is indicated.

    Notes: Abstract Lumbar disc infection, either after surgical discectomy or caused by haematogenous spread from other infection sources, is a severe complication. Specific antibiotic treatment has to be started as soon as possible to obtain satisfactory results in conservative treatment or operative fusion. The aim of this study was to analyse 16 cases of lumbar disc infection, treated with percutaneous lumbar discectomy (PLD) to obtain adequate amounts of tissue for histological examination and microbial culture. Between 1990 and 1994, 26 patients with vertebral osteomyelitis were treated. Sixteen patients, with an average age of 41.4 years (range 14–59 years), underwent a diagnostic PLD. Eight of them showed only moderate changes on computed tomograms (CT scans) and magnetic resonance (MR) images in the initial stages of the disease. The other eight showed more or less extensive osteolytic lesions of one or both vertebral bodies adjacent to the involved disc. The histology results showed non-specific discitis in nine patients and tuberculosis in one. In two patients an open biopsy had been performed, which showed non-specific discitis. Microbiological analysis revealed specific infection in 45% of the patients. These patients received a specific antibiotic treatment after antibiogram for an average of 33 days. Only three patients were treated surgically, with evacuation of the disc space and interbody fusion; the whole group received a spondylitis brace. All patients obtained satisfactory clinical results at the last follow-up regarding pain, mobility and spontaneous fusion of the involved disc space. In conclusion, PLD is a very helpful minimally invasive procedure in conservative treatment of lumbar discitis.
