[Importance of the E. Luque technic in the surgery of major spondylolisthesis in children].

Following a brief summary of results of surgery of major spondylolisthesis of children using Harrington's technique, the outcome in 15 cases operated upon between 1967 and 1983 is discussed. Satisfactory short-term results (reduction perfect in 40% and fair in 60%) were not maintained and a relapse of sliding occurred in 50% at a later stage. In order to improve long-term stability. Harrington's classical procedure was combined with Luque's technique with binding of posterior arches of L3 and L4 to metallic spars in major L5-S1 spondylolisthesis. Two adolescents with very disabling L4-L5 spondylolisthesis were operated upon by Luque's original method combining partial resection of supra- and sub-jacent articular surfaces and isthmic reconstruction by grafts with excellent immediate results. This method is also discussed.
