    OBJECTIVE: Investigate the influence of the extent of posterolateral lumbosacral fusion and its impact on clinical and functional results. METHODS: We evaluated 22 patients with central or foraminal stenosis or lumbar disc herniation associated with segmental instability that underwent to surgery for nerve decompression and posterolateral arthrodesis. Patients were divided into two groups according to the number of levels fused: Group 1: fusion at one level and Group 2: fusion of two or more levels. Patients completed questionnaires regarding postoperative follow-up (use of analgesic medications and treatment satisfaction) and visual analog scale for lumbar pain and sciatica. Moreover, the questionnaires Oswestry and SF-36 were administered to assess quality of life. RESULTS: SF-36 showed good levels of quality of life in both groups, except the field Physical Aspects. There was no significant correlation between the extent of the arthrodesis and clinical outcomes. CONCLUSIONS: Patients who underwent posterolateral arthrodesis showed satisfactory quality of life, except for a decrease of physical fitness. However, the higher number of levels fused did not have negative impact on clinical and functional aspects.

    Radiographic and functional evaluation of the iliac bone graft in the treatment of adolescent idiopathic scoliosis

    This study aimed to assess the impact of the use of an additional iliac bone graft on functional and radiographic results after thoracic spine arthrodesis with pedicle screws in patients with adolescent idiopathic scoliosis. Participants were divided into two groups: a control group that received only local bone (n = 19) and a second group that, in addition to this procedure, received an iliac graft (n = 22). the evaluations were performed on preoperative, immediate postoperative, and last follow-up (mean 29.7 months; minimum 12 months). Radiographic evaluations included the loss of correction and the presence of nonunion. the functional outcome was evaluated using the Scoliosis Research Society-30 questionnaire. Surgical complications and the presence of iliac donor site pain were also described. There were no significant differences between groups in the pseudoarthrosis rate, loss of correction over time, and quality of life. We concluded that the addition of bone graft from the iliac yielded no benefit in terms of the fusion rate and functional outcomes. the appropriate facetectomy, bed preparation, and filling with a local bone graft must be adequate to achieve an adequate fusion on surgical treatment of adolescent idiopathic scoliosis.

    Reliability analysis of radiographic methods for determination of posterolateral lumbossacral fusion
    (Instituto Israelita de Ensino e Pesquisa Albert Einstein, 2014-04-01) Gotfryd, Alberto Ofenhejm; Pomar, Felipe de Moraes; Carneiro Neto, Nicola Jorge; Franzin, Fernando José; Rodrigues, Luciano Miller Reis; Poletto, Patrícia Rios [UNIFESP]; Santa Casa da Misericórdia de Santos; Faculdade de Medicina do ABC; Universidade Federal de São Paulo (UNIFESP)
    ObjectiveTo analyze intra and interobserver agreement of two radiographic methods for evaluation of posterolateral lumbar arthrodesis. MethodTwenty patients undergoing instrumented posterolateral fusion were evaluated by anteroposterior and dynamic lateral radiographs in maximal flexion and extension. The images were evaluated initially by 6 orthopedic surgeons, and after 8 weeks, reassessed by 4 of them, totaling 400 radiographic measurements. Intra and interobserver reliability were analyzed using the Kappa coefficient and Landis and Koch criteria. ResultIntra and interobserver agreement regarding anteroposterior radiographs were, respectively, 76 and 63%. On lateral views, these values were 78 and 84%, respectively. However, the Kappa analysis showed poor intra and interobserver agreement in most cases, regardless of the radiographic method used. ConclusionThere was poor intra and interobserver agreement in the evaluation of lumbosacral fusion by plain film in anteroposterior and dynamic lateral views, with no statistical superiority between the methods.
