    Description / Table of Contents: Summary From 1984 to 1988, 70 consecutive lumbar and lumbosacral spine fusions enhanced with translaminar facet joint screws were performed for segmental degenerative disease. Twenty patients had partial decompression of central stenosis, 15 concomitant discectomy, and 19 lateral nerve root decompression. The mean time to fusion was 4.5 months (range 2–7 months). At follow-up (average 45 months; range 24–74 months) 98.5% were judged to have solid fusion. Satisfactory results were observed in 84% of cases, 91% without previous surgery and 75% after previous discectomy. Supplementation of posterolateral fusion by translaminar facet screws significantly improved time to fusion, fusion rate, and clinical outcomes with no significant increased complications.
    Notes: Résumé De 1984 à 1988, 70 arthrodèses lombaires et lombo-sacrées renforcées par un vissage translamaire des articulations interapophysaires ont été réalisées consécutivement pour des atteintes dégénératives segmentaires du rachis. Vingt patients ont eu dans le m^eme temps une décompression partielle pour sténose centrale, 15 une discectomie et 19 une décompression radiculaire latérale. Le délai moyen de fusion a été de 4,5 mois (valeurs extrêmes: 2–7 mois). A distance (délai moyen: 45 mois; valeurs extrêmes: 24–74 mois), 98,5% des patients présentaient une fusion stable. Les résultants satisfaisants ont été globalement observés dans 84% des cas, dans 91% des cas sans chirurgie préalable et dans 75% des cas après discectomie préalable. Le renforcement de la greffe postéro-latérale par le vissage translamaire des facettes améliore de manière significative de délai et le taux de fusion ainsi que les résultats cliniques, sans augmentation significative du taux des complications.

    Notes: Abstract Vertebral arthrodesis is one of the most commonly performed, yet incompletely understood, procedures in spinal surgery. Despite major progress in internal fixation techniques, the high rate of non-unions indicates that physiologic, biologic and molecular events that are crucial to this process are not well known. This article will analyze the general biology of bone regeneration, and particularly discuss the properties and use of various bone graft materials and graft substitutes.
