Thirty-four patients who had central stenosis of the lumbar spine were treated with wide fenestration, a procedure in which only the medial parts of the inferior facets and the adjoining ligamentum flavum were removed. The patients were followed for an average of five and one-half years (range, four and one-half years to seven years and ten months). Wide fenestration successfully relieved the symptoms. The new bone that was laid down in the operatively treated segments did not reproduce the symptoms of spinal stenosis; instead, it appeared to stabilize those segments.
34例腰椎中央管狭窄患者接受了广泛开窗手术治疗,该手术仅切除下关节突内侧部分及相邻的黄韧带。对这些患者平均随访了5年半(范围为4年半至7年10个月)。广泛开窗手术成功缓解了症状。手术治疗节段形成的新骨未重现椎管狭窄症状;相反,它似乎使这些节段更加稳定。
