目的 观察比较盐酸氨基葡萄糖单独使用及与硫酸软骨素联合使用治疗腰椎小关节骨关节炎（LFOA） 的临床疗效。 方法 2009年1月－2011年1月，将80例LFOA患者随机分成两组，A组口服盐酸氨基葡萄糖，B组口服盐酸氨基葡萄糖和硫酸软骨素两种药物，6周为1个疗程，间断治疗4个疗程。分别比较用药前与用药后3、6周及5、8、11个月时的日本骨科协会（JOA）评分、晨僵和压痛程度变化。 结果 治疗后，两组的JOA评分在各观察时点均增加，与治疗前比较差异有统计学意义（P＜0.05）。组间行JOA评分治疗改善率的比较，在各观察时点差异均有统计学意义（P＜0.05），B组JOA评分改善率优于A组。治疗3周后，两组晨僵和压痛评分均降低，与本组治疗前比较差异有统计学意义（P＜0.05）；组间比较，差异亦有统计学意义（P＜0.05），B组晨僵和压痛程度均低于A组。第6周，第5、8、11个月，两组组间比较晨僵和压痛程度差异均无统计学意义（P＞0.05），但各疗程结束后两组晨僵和压痛程度均呈持续降低趋势。 结论 单独应用盐酸氨基葡萄糖及盐酸氨基葡萄糖与硫酸软骨素的联合应用治疗LFOA疗效确切，联合用药优于单独应用盐酸氨基葡萄糖。
Objective To explore the cl inical appl ication of rib autograft for reconstructing il iac crest by anterior approach of thoracic and lumbar vertebrae, and to observe the short-term and long-term effects. Methods From September 2004 to September 2007, 54 cases of thoracic and lumbar injuries were treated by the surgery of anterior approach of thoracic and lumbar vertebrae.There were 39 males and 15 females with an average age of 42 years old (range, 27-59 years old), including 4 cases of tuberculosis of spine and 50 cases of thoracic and lumbar vertebrae bursting fracture. All cases underwent the surgery of anterior approach of thoracic or lumbar and il iac crest was used as autograft. Fifty-four patients wererandomized into the reconstruction group (RG, n=25) and the non-reconstruction group (NRG, n=29). The patients of RGgroup were treated with rib autograft for reconstructing il iac crest. There were no statistically significant differences in general data between two groups (P gt; 0.05). The visual analogue scores (VAS) was used to estimate pain degree of treated hip after 2 weeks, and 3, 12 months. The extenion satisfaction grade of il iac crest and the comfort degree of action while bundl ing waist belt were estimated after 12 months. It was observed whether or not anterior superior il iac spine avulsion fracture occurred on the premise of non-accidental trauma within 1 year. The occurrence of fracture and the union status of reconstructed il iac crest were observed by X-ray after 1 year. Results All wounds achieved primary heal ing. No compl ication was found at early stage. All patients were followed up 1 year. There was no significant difference in the VAS of the treated hip under conditions of cl inostatism rest between two groups after 2 weeks and 3 months (P gt; 0.05). But there was significant difference in the VAS under conditions of action after 2 weeks and 3 months, under conditions of cl inostatism rest after 12 months (P lt; 0.05), and the VAS of RG was lower than that of NRG. The exterior satisfaction grade of il iac crest and comfort degree of action while bundl ing waist belt in RG were higher than those in NRG after 1 year, showing significant differences (P lt; 0.05). No anterior superior il iac spine avulsion fracture occurred after 1 year. And in RG group no fracture of reconstructed il iac crest occurred after 1 year. The X-ray film showed that the two ends of rib reconstructed by il iac crest were blur, and that the rib healed well with il iac bone. Conclusion Rib autograft for reconstruction of il iac crest by anterior approach of thoracic and lumbar vertebrae was economic and convenient. It could improve local appearance, reduce the local pain, and improve patients’ l ife quality.
