目的 探讨单用和联用盐酸氨基葡萄糖与非甾体抗炎药（NSAID）在椎间盘源性腰痛（DLBP）治疗中的有效性。 方法 2011年1月－12月72例DLBP患者，男42例，女30例；年龄22～71岁；体重43～84 kg；病程0.5～10年。通过随机数字表的方法，将患者分为3组。A组给予盐酸氨基葡萄糖胶囊750 mg，2次/d，同时给予尼美舒利分散片100 mg，2次/d；B组给予盐酸氨基葡萄糖胶囊750 mg，2次/d；C组给予尼美舒利分散片100 mg，2次/d。3组均用药8周后停药，用药期间停用其他活血化瘀类药物及物理治疗。选取治疗前及治疗后第4、8、16周4个时间点，运用疼痛数字评价量表（NRS）、Oswestry功能障碍指数（ODI）、生活质量评价量表SF-36分别对3组患者的腰痛、腰部功能及生活质量进行评价。 结果 63例获得随访，失访率12.5%。各组患者NRS评分、ODI评分、SF-36评分在治疗前后比较差异均有统计学意义（P＜0.05），A组疗效明显优于B、C两组，B组治疗后各项数据较治疗前明显改善（P＜0.05）。 结论 单用盐酸氨基葡萄糖治疗DLBP有效，且在停药后，仍有一定疗效，联用NSAID效果更佳；远期疗效有待进一步随访。
【Abstract】 Objective To investigate the effectiveness of surgical treatment for discogenic low back pain (DLBP) by minimally invasive transforaminal lumbar interbody fusion (TLIF) combined with unilateral pedicle screw fixation (UPSF). Methods Between March 2006 and July 2009, 57 patients with single-level DLBP were treated by minimally invasive TLIF combined with UPSF, including 27 males and 30 females with an average age of 45.6 years (range, 38-61 years) and a disease duration of 3.8 years (range, 9 months to 11 years). The involved segments included L2，3 in 2 cases, L3，4 in 5 cases, L4，5 in 29 cases, and L5, S1 in 21 cases. The operative time, incision length, intraoperative blood loss, postoperative drainage volume, hospitalization times, fusion rate, and complications were observed. The effectiveness were evaluated through Oswestry disability index (ODI) and visual analogue score (VAS), and the operative outcomes were compared in different groups classified according to various pressures of the contrast medium and sensitivities to discoblock after inducing consistent pain. Results The operation time, incision length, blood loss, postoperative drainage volume, and hospitalization times were (84.6 ± 37.4) minutes, (3.4 ± 0.6) cm, (132.5 ± 23.2) mL, (58.7 ± 21.4) mL, and (6.5 ± 0.8) days, respectively. All patients were followed up 2 years and 2 months to 5 years and 4 months (mean, 3.2 years). At last follow-up, ODI and VAS scores were significantly improved when compared with preoperative scores (P lt; 0.05). The effectiveness according to ODI were excellent in 27 cases, good in 22 cases, fair in 6 cases, and poor in 2 cases, with an excellent and good rate of 86.0%. All patients acquired b interbody fusion. At last follow-up according to ODI and VAS scores, better results were found in patients of low-pressure sensitive group and high-sensitive discoblock group (P lt; 0.05). Conclusion Minimally invasive TLIF combined with UPSF is reliable for DLBP with minimal surgical trauma, less paravertebral tissue injury, and fewer complications, but the indications for operation must be strictly followed. Patients being sensitive to low-pressure or high-sensitive to discoblock can achieve better surgical results.
目的:评价经皮激光椎间盘减压术(Semiconductor Percutaneous Laser Disc Decompression,PLDD)治疗椎间盘源性腰痛的疗效。方法:对我院采用SPLDD治疗d的56例进行回顾性分析。经皮激光椎间盘减压术(PLDD)治疗椎间盘源性腰痛56例(70个椎间盘),每只椎间盘需激光能量如下:L3～4、L5～S1为:1 200～1 400J;L4～5为1300～1500J。比较手术前后疼痛强度数字等级 (pain intensity numerical rating scale, PINRS)评分,进行疗效观察和评定术后根据症状缓解程度。结果:随访3月为(2.1±0.4)分 (与术前比较,Plt;0.05);本组56例病例中,PINRS评分由术前平均(8.0±0.3)分改善到术后(2.0±0.2),共39例,占69.6%;(9.0±0.5)分改善到术后(4.0±0.6)共17例,占30.4%。未见椎间盘炎及其他并发症发生。手术时间15～60m in,平均30 m in。结论:SPLDD治疗椎间盘源性腰痛安全、有效、微创,值得推广。
Objective To evaluate the clinical effects of surgical treatment for 30 patients with discogenic low back pain. Methods A total of 30 patients with 36 intervertebral discs were treated with posterior approach lumbar discectomy and interbody fusion with internal fixation by strict criteria. All patients were followed up for one year. The low back pain before and one year after surgery was evaluated by Japanese Orthopaedic Association (JOA) score and Visual Analogue Scale (VAS) score. Results The patients’ JOA score increased from 14.6±2.3 (before operation) to 27.1±0.9 (one year after operation) (t=–26.936, P<0.001), while the patients’ VAS score decreased from 6.2±1.6 (before operation) to 1.4±0.9 (one year after operation) (t=16.335, P<0.001), and the differences were significant. Conclusion When the conservative treatment is invalid, the operation of posterior lumbar intervertebral fusion is an effective method for the patinets with discogenic low back pain.
Objective To summarize the research progress of platelet-rich plasma (PRP) for the treatment of discogenic low back pain (DLBP). Methods The literature on the treatment of DLBP with PRP was extensively reviewed, and the classification, treatment mechanism, in vitro and in vivo experiments and clinical trial progress of PRP were summarized. Results According to the PRP composition, preparation methods, and physicochemical properties, there are five commonly used PRP classification systems at present. PRP is involved in delaying or reversing the progress of disc degeneration and pain control by promoting the regeneration of nucleus pulposus cells, increasing the synthesis of extracellular matrix, and regulating the internal microenvironment of degenerative intervertebral disc. Although several in vitro and in vivo studies have confirmed that PRP can promote disc regeneration and repair, significantly relieve pain, and even improve the mobility of DLBP patients. But the contrary conclusion has been reached in a few studies, and there are limitations to the application of PRP. ConclusionCurrent studies have confirmed the effectiveness and safety of PRP in the treatment of DLBP and intervertebral disc degeneration, as well as the advantages of PRP in terms of ease of extraction and preparation, low immunological rejection, high regenerative and repair capacity, and the ability to compensate for the shortcomings of traditional treatment modalities. However, relevant studies are still needed to further optimize PRP preparation methods, unify systematic classification guidelines, and clarify its long-term effectiveness.
