摘要 目的探讨直接修复加钩钉固定术治疗腰椎弓崩裂的临床效果。方法采用自体骨直接修复联合椎板钩、椎弓根钉固定术治疗急性腰椎弓崩裂35例,其中男25例,女10例。随访并根据影像学结果及MacNab标准进行临床评价。结果直接修复加钩钉固定术能有效恢复腰椎稳定性,无手术及内固定相关的并发症发生。手术后平均随访10个月,除2例术后单侧椎弓崩裂处不融合外,其余患者均获得植骨愈合。按MacNab标准:优、良31例,一般4例。结论椎板钩-椎弓根钉应用于青年性腰椎弓崩裂直接修复后固定,可在减少融合节段的同时能有效恢复腰椎稳定。临床应用简便、安全、有效。 Objective: To explore the clinical effect of hook plus screw fixation after direct repair of lumbar spondylolytic defects in the pars inter articularis.Methods: Thirty-five young cases suffered from symptomatic lumbar spondylolysis were selected and treated with hook screw fixation after direct repair of the defect.MacNab criteria were used to assess their pre-and post-operative status.Results: Hook plus screw technique significantly increased stiffness and the intervertebral rotational stiffness nearly returned to intact levels.Neither complications nor instrumentation failurewere was observed.The mean 10 months follow-up showed excellent or good results in 31 cases,and ordinary results in 4 cases according to MacNab criteria.Conclusion: Hook plus screw fixation can reduce fusion segments and recover stability of the lumbar vertebrae,which is clinically simple,safe and effective.
