摘要:

文题释义:

前交叉韧带胫骨止点撕脱骨折:为前交叉韧带胫骨髁间嵴在遭受剧烈运动或暴力作用下发生的撕脱骨折,属关节内损伤。由1875年Poncet首次描述,早期常见于儿童的儿童型前交叉韧带撕裂,近年来发病率有所增高。骨折移位较大时造成的愈合畸形或不愈合容易导致前交叉韧带松弛甚至丧失功能,最终导致膝关节功能障碍或不稳。

Fiber Tape:型号AR-7237-7,由Arthrex公司提供。为不可吸收、宽2 mm扁平超高分子量聚乙烯与聚酯编织的缝合线,中部为扁平带状,逐渐过渡到两端的圆柱状结构,具有一定柔软性及相当的韧性,常被应用到肩袖修复或肩锁关节重建。具有良好的手感和打结能力,滑结前进顺利,简化了关节镜打结程序。多个独立的科学研究证明其在断裂强度、刚度、结强度和结滑移方面更具优势,但延伸率要低得多。广泛的生物相容性、动物和临床试验结果证明其具有与标准聚酯缝合线相当的生物相容性特征。

背景:前交叉韧带胫骨止点撕脱性骨折需尽早行手术复位内固定,目前临床治疗方案中常用切开复位(可吸收螺钉、空心钉、钢丝、钛缆等)内固定,创伤较大,术后并发症多。而关节镜下行前交叉韧带下止点骨折复位弹性(缝线)内固定具有微创、术野清晰、固定准确性高、并发症少、骨折复位愈合好、符合生物力学要求、关节功能康复快等优点,但也有强度不够、骨块切割等缺点。

目的:比较关节镜下Fiber Tape环形固定与开放内固定治疗前交叉韧带下止点撕脱骨折的疗效。

方法:收集2017年1月至2018年12月上海中冶医院骨科收治的32例前交叉韧带下止点撕脱骨折患者,所有患者对治疗方案均知情同意,且得到医院伦理委员会批准。根据手术方法分成2组,微创组17例采用关节镜下Fiber Tape环形固定治疗;开放组15 例采用开放手术骨折复位(空心拉力螺钉、钛缆、钢丝等)内固定治疗。记录所有患者手术时间、出血量、术后并发症情况;于术前及术后第1,6个月记录膝关节活动范围、Lysholm评分及国际膝关节评分委员会评分,摄X射线片评价骨折复位愈合情况。

结果与结论:①所有患者获得随访,时间6-13个月;②2组患者年龄组成、骨折类型、受伤原因、术前评分差异无显著性意义;③术后X射线片复查骨折均得到满意复位,术后未出现神经、血管损伤、骨折移位情况,术后6个月骨折均愈合良好;④2组手术时间、术后并发症发生率差异无显著性意义,2组术中出血量差异有显著性意义(P=0.036);⑤膝关节活动度:2组患者术后1个月膝关节活动度显著大于术前(P < 0.05),术后6个月膝关节活动度显著大于术后1个月(P < 0.05);术后1,6个月微创组膝关节活动度显著大于开放组(P < 0.05);⑥Lysholm膝关节功能评分及国际膝关节评分委员会评分:2组患者术后1个月Lysholm 膝关节功能评分及国际膝关节评分委员会评分均显著高于术前(P < 0.05),术后6个月评分均显著高于术后1个月(P < 0.05);术后1,6个月微创组评分均显著高于开放组(P < 0.05);⑦提示2组患者经过手术干预膝关节屈伸活动大部分恢复,且随时间延长恢复程度越高。与开放内固定(空心拉力螺钉、钛缆、钢丝等)相比,关节镜下Fiber Tape环形固定治疗前交叉韧带下止点撕脱骨折的出血更少,创伤更小,关节功能恢复时间更短,恢复程度更高。

Abstract:

BACKGROUND: The avulsion fracture of tibial insertion of anterior cruciate ligament needs to be operated and fixed as early as possible. At present, the open reduction (absorbable screw, hollow screw, steel wire, and titanium cable) is commonly used in the clinical treatment plan for internal fixation, which is more traumatic and has many postoperative complications. Arthroscopic reduction and elastic (suture) internal fixation of anterior cruciate ligament fracture has the advantages of minimally invasive, clear surgical field, high fixation accuracy, few complications, good fracture reduction and healing, meeting the biomechanical requirements, and allowing rapid recovery of joint function, but also has the disadvantages of insufficient strength, and osteotomy.

OBJECTIVE: To compare the treatment efficacy of arthroscopic technique with Fiber Tape circular fixation and open reduction and fixation for the avulsion fracture of tibial insertion of anterior cruciate ligament.

METHODS: Thirty-two patients with tibial eminence fracture at Department of Orthopedics of Shanghai China Metallurgical Hospital from January 2017 to December 2018 were enrolled. All patients signed the informed consents and the study was approved by the Ethics Committee. The patients were divided into two groups based on surgical methods: minimally invasive group (n=17, arthroscopic reduction and Fiber Tape circular fixation) and open group (n=15, open reduction and hollow tension screw fixation). The operation time, blood loss, and postoperative complications were recorded. The range of motion of knee joint, Lysholm score, and International Knee Documenting Committee score before operation, 1 and 6 months after surgery were recorded. X-ray film was used to evaluate fracture healing.

RESULTS AND CONCLUSION: (1) All patients were followed up for 6-13 months. (2) There were no significant differences in age composition, fracture type, cause of injury or preoperative score between two groups. (3) X-ray film showed satisfactory fracture reduction after operation. There were no neurological, vascular injury or fracture displacement after surgery. The fractures healed well after 6 months. (4) There was no significant difference in the operation time and postoperative complications between two groups. The blood loss showed significant difference between two groups (P=0.036). (5) The range of motion of knee joint at postoperative 1 month in both groups was significantly larger than that at baseline (P < 0.05). The range of motion of knee joint at postoperative 6 months was significantly larger than that at postoperative 1 month (P < 0.05). The range of motion of knee joint at postoperative 1 and 6 months in the minimally invasive group was significantly larger than that in the open group (P < 0.05). (6) The Lysholm and International Knee Documenting Committee scores at postoperative 1 month in both groups were significantly higher than those at baseline (P < 0.05). The scores at postoperative 6 months were significantly higher than those at postoperative 1 month (P < 0.05). The scores at postoperative 1 and 6 months in the minimally invasive group were significantly higher than those in the open group (P < 0.05). (7) These findings suggest that the patients in both groups after undergoing surgical methods had restored motion of range with time going. Compared with open fixation, arthroscopic reduction and Fiber Tape circular fixation for treating tibial eminence fracture has less blood loss, less trauma, shorter recovery time and higher functional recovery.
