  • 关节镜下前交叉韧带重建术后早期感染三例

    目的 报道 3 例关节镜下前交叉韧带重建术后早期感染患者临床资料,总结治疗方法及疗效,分析预防措施。 方法 2015 年 3 月—2017 年 3 月,关节镜下前交叉韧带重建术后 3 例发生早期感染。其中男 2 例,女 1 例;年龄 30、39、32 岁。术后 7 d 出现膝关节疼痛伴低热症状,均存在关节腔积液,其中 1 例积液细菌培养呈阳性;白细胞计数及中性粒细胞计数在正常范围,超敏 C-反应蛋白及红细胞沉降率升高。2 例给予万古霉素、1 例给予关节镜下关节腔清理术后治愈。 结果 3 例患者经抗感染治疗后,临床症状及体征均消失,感染治愈;白细胞计数及中性粒细胞计数、超敏 C-反应蛋白、红细胞沉降率均在正常范围。术后 90 d 膝关节 Lysholm 评分为 89、88、80 分。 结论 关节镜下前交叉韧带重建术后早期感染的发生可能与手术时间延长及关节腔积液有关,经长期口服利福平抗感染治疗后可获较好临床疗效。

  • SHORT-TERM EFFECTIVENESS OF Quadrant RETRACTOR IN TREATMENT OF RECURRENT LUMBAR DISC PROTRUSION

    Objective To investigate the effectiveness of Quadrant retractor for the treatment of recurrent lumbar disc protrusion. Methods Between July 2008 and March 2010, 18 cases of recurrent lumbar disc protrusion were treated with Quadrant. There were 13 males and 5 females with an average age of 43 years (range, 35-67 years). Involved segments includedL4, 5 in 6 cases and L5, S1 in 12 cases. The time between first operation and recurrence was 12-120 months (mean, 42.8 months). Before operation, radiological evaluation including X-ray, CT, and MRI were performed. Visual analogue scale (VAS) score and modified MacNab criteria were used to evaluate the effectiveness. Results The operation time was 40-80 minutes (mean, 60 minutes), and the amount of blood loss was 80-120 mL (mean, 100 mL). All operations were performed successfully, and no compl ication of infection and nerve injury occurred. Incisions healed by first intention. Cerebrospinal fluid leakage occurred in 2 cases and was cured at 3 days after operation by removal of drainage. Eighteen patients were followed up 12-30 months (mean, 22 months). The VAS score of leg pain was decreased from 7.3 ± 2.2 preoperatively to 2.0 ± 1.3 at the final follow-up, showing significant difference (t=11.08, P=0.00). According to modified MacNab criteria, the results were excellent in 12 patients and good in 6 patients. No recurrence was found during follow-up. Conclusion Discectomy via Quadrant retractor is a safe and effective minimally invasive surgical technique in treating recurrent lumbar disc protrusion.

  • RESEARCH OF SINGLE INCISION VIA MAST QUADRANT RETRACTOR IN MANAGEMENT OF LUMBAR SPONDYLOLISTHESIS

    Objective To evaluate the effect of posterior lumbar interbody fusion (PLIF) using single incision via MAST Quadrant retractor in the management of lumbar spondylolisthesis. Methods From July 2008 to June 2009, 20 cases of lumbar spondylolisthesis were treated with posterior lumbar interbody fusion via MAST Quadrant retractor using single incision,including 2 cases of degenerative spondylolisthesis and 18 cases of isthmic spondylolisthesis. There were 8 males and 12 females aged from 34 to 62 years (average 45.5 years). The disease course was 1 to 6 years (mean 34.5 months). The spondylol isthesis locations were L4,5 in 8 cases and L5, S1 in 12 cases. According to Meyerding classification, all cases were classified as degree I. The Visual Analogue Scale (VAS) score was (6.6 ± 1.2) points. The operative time, the blood loss, and the therapeutic effects were recorded. Results The operative time was (155 ± 23) minutes and the amount of blood loss was (360 ± 102) mL. The hospitalization time were (12.0 ± 3.4) days. All incisions healed by first intention. X-ray films showed spondylolisthesis reduction immediately after operation. All patients were followed up 14.3 months on average (from 9 to 20 months). The VAS score decreased to (1.6 ± 2.3) points at the last follow-up, showing significant difference when compared with that of preoperation (P lt; 0.05). The X-ray films showed that lumbar interbody fusion was achieved in all the patients. No lossening, breakage, and displacement of pedicle screw fixation was observed. According to Nakai standard, the results were excellent in 18 cases and good in 2 cases at the last follow-up. Conclusion As long as the indication is strictly chosen, PLIF via MAST Quadrant retractor is a safe, effective, and minimally invasive surgical technique in treating lumbar spondylolisthesis.
