目的:探讨经皮穿刺颈椎髓核成形术(percutaneous cervical nucleoplasty,PCN)治疗多间隙颈椎间盘突出症的临床疗效及其对颈椎稳定性的影响。方法:对我院2003年7月～2005年6月因颈椎间盘突出症住院行PCN治疗的64例患者进行回顾性研究,根据手术间隙分为两组:单间隙组(A组)34例,多间隙组(B组)30例。临床效果评价采用JOA评分标准(17分制并计算改善率),颈椎稳定性评价采用Katsumi标准。比较两组的临床效果及颈椎稳定性。结果:随访6～24个月,A组平均14.1±3.7个月,B组平均13.9±3.8个月,A组术前JOA评分为9.19±2.64分,术后为14.37±1.42分,改善率为66.3%;B组术前JOA评分为8.89±2.31分,术后为14.33±1.28分,改善率为67.1%,与术前比较均有显著性差异(P<0.001),两组患者的JOA评分改善率无显著性差异(P>0.05)。两组患者术后颈椎稳定性与术前比较均无显著性差异(P>0.05)。结论:PCN治疗多间隙颈椎间盘突出症效果优良,对颈椎稳定性影响小,不会造成颈椎失稳。     

Histologic findings of disc, end plate and neural elements after coblation of nucleus pulposus: an experimental nucleoplasty study

BACKGROUND CONTEXT: Partial removal of the nucleus has been shown to decompress herniated discs, relieving pressure on nerve roots and, in some cases, offering relief from disc pain. The nucleoplasty technique builds on earlier surgical approaches that helped validate the strategy of intranuclear tissue removal. Nucleoplasty, a new minimally invasive procedure using patented coblation technology, combines coagulation and ablation for partial removal of the nucleus pulposus to decompress the disc. PURPOSE: To determine if histologic changes of the intervertebral discs and surrounding tissues occur after nucleoplasty. STUDY DESIGN: A light microscopic study of intervertebral disc and adjacent neural tissues after disc decompression by nucleoplasty in pig cadavers. METHODS: Light microscopy was used to examine disc and neural tissues in two pig cadaveric specimens (T12 to sacrum). Nucleoplasty was performed by 1) advancing a radiofrequency wand to a predetermined depth in the disc (ablation), and 2) withdrawing the wand to the starting point (coagulation). Discs and adjacent tissues were removed from treated and nontreated segments, and examined under light microscopy. RESULTS: Histologic examination revealed no evidence of direct mechanical or thermal damage to the surrounding tissues. There was clear evidence of coblation channels with clean coagulation borders of the nucleus pulposus. Normal histologic findings of the annulus and end plate, with normal neural elements of the spinal cord and nerve roots at the level of the procedure, were observed. CONCLUSIONS: The histologic findings of this study suggest that the nucleoplasty achieves volumetric removal of target disc tissue without overt thermal or structural damage to the adjacent tissues. Further studies in live animals will be needed to assess the effects of nucleoplasty on the annulus, end plate and neural tissues under physiologic conditions, including assessment of cell viability.
