开窗减压术治疗中央型腰椎管狭窄症

１９８６年以来，使用开窗减压术治疗中央型腰椎管狭窄症５３例，４９例（９２．５％）得到随访，优良率达９１．８％，仅有１例发生术后腰椎不稳。该手术损伤小，在较大程度上保留了腰椎后部结构均完整性，术后腰椎稳定性好，硬膜及神经根不易发生瘢痕粘连。虽然开窗减压范围小，但通过腰椎两侧对称性和多节段开窗，椎管可得到充分减压。临床应用表明该法较传统的椎板切除术疗效好。

Treatment of central lumbar spinal stenosis with fenestration decompression

Since 1986, 53 cases of central lumbar spinal stenosis have been treated with fen- estration decompression. A follow-up of 49 cases (92. 5%) showed that 91. 8% of the patients had an excellent or good result. Lumbar instability at the operated level occurred in only 1 case(2%). The fenestration yield less trauma for lumbar spine and to a great extent, maintained the integrity of the posterior structure of the lumbar spine, postoperative stability of lumbar spine in good condition, and less scar tissue adherent of the dura and the nerve root. Although the extent of the operative decompression was limited, the spinal canal can be decompressed sufficiently by bilateral symmetrical and multi-segmental fenestation This method has been prove better than the traditional laminectomy.
