We assessed in this study the potential development of postoperative muscle atrophy in the operation area in 39 patients treated by either microdiscectomy or percutaneous nucleotomy for lumbar disc herniation. The cross-sectional areas of the lumbar muscles were measured on magnetic resonance images created on the day preceding the operation and 6 months postoperatively. The cross-sections of the lumbar muscles remained unchanged during the observation period in all treated patients indicating that no muscle atrophy had developed in the operation area. Since peroperative tissue trauma may correlate with subsequent muscle denervation and atrophy, this finding may be due to the tissue sparing nature of microdiscectomy and percutaneous nucleotomy, thus encouraging the use of these techniques in the treatment of lumbar disc herniation.
在本研究中，我们评估了39例接受显微椎间盘切除术或经皮髓核切除术治疗腰椎间盘突出症患者手术区域术后肌肉萎缩的潜在发展情况。在手术前一天和术后6个月所拍摄的磁共振图像上测量腰椎肌肉的横截面积。在所有接受治疗的患者中，腰椎肌肉横截面积在观察期内保持不变，这表明手术区域未发生肌肉萎缩。由于术中组织创伤可能与随后的肌肉去神经支配和萎缩相关，这一发现可能归因于显微椎间盘切除术和经皮髓核切除术对组织的微创特性，从而鼓励在腰椎间盘突出症治疗中使用这些技术。
