On the basis of previous EMG data, a retrospective study was carried out on the CT and MR features of the paravertebral musculature after lumbar spine surgery through the posterior approach. The authors reviewed the CT scans and some MR images of 35 symptomatic patients hospitalized 7 months to 42 years after operation for disc herniation. Changes in the paraspinal musculature were apparent in all of them on the surgical side. The changes were minimal or very slight in 14 patients, moderate in 13 and severe in 8. A close correlation was observed between the above changes and the surgical procedure used in every single case. Histology showed atrophy and degeneration of the muscle fibres and fibrofatty substitution. The possible responsible causes of damage to the postvertebral muscles during spinal surgery are briefly mentioned and practical implications discussed.
基于先前的肌电图数据，通过后路对腰椎手术后椎旁肌肉组织的CT和MR特征进行了一项回顾性研究。作者回顾了35例因椎间盘突出症术后7个月至42年住院的有症状患者的CT扫描和部分MR图像。所有患者手术侧的椎旁肌肉组织均有明显变化。14例患者变化轻微或非常轻微，13例为中度，8例为重度。观察到上述变化与每例患者所采用的手术方式密切相关。组织学显示肌纤维萎缩、变性及纤维脂肪替代。简要提及了脊柱手术中椎旁肌肉损伤的可能原因并讨论了实际意义。
