摘要:

文题释义:

迷你锁定钛板系统:为生物性不可吸收材料,内固定螺钉直径为1.5 mm,钉板之间有锁定固定螺纹,该系统具有高强度、高韧性、耐磨性等特点,适合微小骨折固定。
腕舟骨骨折:是一种常见的腕部损伤,该处是腕关节稳定性和活动性的重要承载力学部位,如诊断或治疗不及时,常易引起腕舟骨坏死以及创伤性腕关节炎等后遗症。

背景:腕舟骨骨折治疗的基本原则是即刻刚性固定,恢复生物力学性能,重建解剖结构和血供,由于其独特的解剖特点和血供,容易出现漏诊和骨不连。
目的:探讨采用迷你锁定钛板系统内固定治疗腕舟骨骨折的效果,分析其临床应用前景。
方法:纳入腕舟骨骨折患者40例,随机分为2组,试验组采用迷你锁定钛板系统固定,对照组采用双螺纹空心埋头钛钉固定,每组20例。观察围术期指标(手术时间、术中透视次数、术后住院时间),每月临床随访时记录骨折愈合时间,术前和术后3,8,12个月时评估患者的局部疼痛目测类比评分和腕关节功能评分(Mayo评分)。
结果与结论:①两组患者均完成12个月以上随访,对照组留置内固定,试验组在术后6个月时取出内固定进行康复训练;②两组围术期指标中,试验组在手术时间和术中透视次数方面均具有优势(P < 0.05),在术后住院时间方面两组差异无显著性意义(P > 0.05);③在骨折愈合时间方面,试验组骨折愈合时间短(P < 0.05);④术后1年随访时,两组的目测类比评分、Mayo腕关节功能评分相比,差异无显著性意义  (P > 0.05);⑤提示采用迷你锁定钛板系统进行腕舟骨的内固定治疗具有一定的临床可行性,其较为稳定的固定系统可以实现骨折的解剖复位,抗旋能力强,骨折愈合时间短,临床疗效肯定;而且在直视下的手术操作,可减少手术的操作难度和透视次数。

Abstract: BACKGROUND: The basic principles of carpal scaphoid fracture treatment are immediate rigid fixation, restoration of biomechanical properties, reconstruction of anatomical structure and blood supply. Due to its unique anatomical characteristics and blood supply, it is prone to missed diagnosis and nonunion.
OBJECTIVE: To explore the treatment effect of a mini-locking titanium plate system on carpal scaphoid fracture, and analyze its clinical application prospects.
METHODS: Forty patients with carpal scaphoid fractures were included and randomly assigned to two groups. Patients in the trial group were fixed with mini-lock titanium plate system (n=20). Patients in the control group were fixed with double-thread hollow countersunk titanium nail (n=20). Perioperative indicators (operation time, intraoperative fluoroscopy and postoperative hospital stay) were observed. Fracture healing time was recorded every month during follow-up. Visual analogue scale score of local pain and wrist function score (Mayo score) were evaluated preoperatively, 3, 8 and 12 months postoperatively. 
RESULTS AND CONCLUSION: (1) Both groups of patients completed more than 12 months of follow-up. The double-threaded hollow countersunk titanium nail was placed with internal fixation in the control group, and the mini-lock titanium plate system was taken out of the internal fixation for rehabilitation training in the trial group at 6 months postoperatively. (2) Among the two groups of perioperative indicators, the trial group had an advantage in terms of operation time and intraoperative fluoroscopy (P < 0.05), and there was no significant difference in the length of postoperative hospital stay (P > 0.05). (3) In terms of fracture healing time, the time of the trial group was short (P < 0.05). (4) At 1-year follow-up, there was no significant difference in visual analogue scale score or wrist function score (Mayo score) between the two groups (P > 0.05). (5) It is indicated that the use of a mini-locking titanium plate system for surgical treatment of the carpal scaphoid has certain clinical feasibility. Its relatively stable fixation system can achieve fracture anatomical reduction, strong anti-rotation ability, short fracture healing time, and the patient’s clinical efficacy is positive. This surgical plan is a surgical operation under direct vision, which reduces the difficulty of the operation and the number of fluoroscopy.
