乔氏架:为西安市红会医院乔锋教授模拟泰勒氏空间支架设计的数字化六轴外架技术,与泰勒氏基于X射线数据不同,乔氏架以CT数据为基础,可以精准复位骨折,并应用于下肢骨折和矫形治疗,称之为乔氏架技术。

摘要
背景:外固定架发展的趋势是智能化和小型化,西安市红会医院乔锋教授设计的数字化六轴外架技术,以CT数据为基础,可以精准复位骨折,并应用于下肢骨折和矫形治疗,称之为乔氏架技术。考虑到数字化六轴外架体积较大,乔锋教授又研发了数字化六轴外架辅助复位、单臂外固定架技术治疗胫骨干骨折,所研发的单臂外固定架体积小,可以与六轴外架相耦合,费用相对同类外架Taylor架低。
目的:探讨数字化六轴外架(乔氏架)辅助复位、单臂外固定架固定治疗胫骨干骨折的有效性和可靠性。
方法:回顾性分析西安市红会医院中西医结合骨科2018年1月至2022年12月使用乔氏架治疗的胫骨干骨折患者103例,根据固定方案分为2组:乔氏架组51例,乔氏架+单臂外固定架组(乔氏架辅助复位、单臂外固定架固定)52例。复位后4周在X射线片上测量骨折的移位距离和成角。使用独立样本t检验和卡方检验对比骨折的移位、骨折愈合时间、下肢功能评分及针道并发症发生率。
结果与结论:①乔氏架组与乔氏架+单臂外固定架组复位后4周的骨折移位相比差异无显著性意义(P > 0.05);②两组患者的骨折愈合时间、下肢功能评分、针道感染率相比差异均无显著性意义(P > 0.05);③与乔氏架组相比,乔氏架+单臂外固定架组针道牵拉痛发生例数显著减少(15例 vs. 2例),差异有显著性意义(P < 0.05);④提示乔氏架辅助单臂外固定架固定技术通过耦合数字化六轴外架与单臂结构,在实现解剖复位和稳定固定的同时,显著降低了传统环形外固定架的体积,且针道并发症发生率更低,为闭合性及开放性胫骨干骨折提供了一种微创有效的治疗选择。

Abstract: BACKGROUND: The trend in external fixator development is towards intelligence and miniaturization. Professor Qiao Feng of Xi'an Honghui Hospital designed a digital six-axis external fixator technology, based on CT data, which can accurately reduce fractures and is applied to lower limb fracture and orthopedic treatment, known as the Qiao’s spatial frame technology. Considering the large size of the digital six-axis external fixator, Professor Qiao Feng further developed a digital six-axis external fixator-assisted reduction and unilateral external fixator technology for the treatment of tibial shaft fractures. The developed unilateral external fixator is small in size, can be coupled with the six-axis external fixator, and is relatively less expensive than similar external fixators such as the Taylor spatial frame.
OBJECTIVE: To explore the effectiveness and reliability of digital six-axis external frame (Qiao’s spatial frame) assisted reduction and unilateral external fixator fixation for the treatment of tibial shaft fractures.
METHODS: A retrospective analysis was conducted on 103 patients with tibial shaft fractures treated with digital external fixators in the Department of Integrated Traditional Chinese and Western Medicine Orthopedics of Xi'an Honghui Hospital from January 2018 to December 2022. The cases were divided into a Qiao’s spatial frame group (n=51) and a Qiao’s spatial frame assisted reduction and unilateral external fixator fixation group (n=52). The displacement distance and angle of the fracture were measured on X-rays 4 weeks after reduction. Independent sample t test and chi-square test were used to compare fracture displacement, fracture healing time, lower extremity functional score and the incidence of pin tract complications.
RESULTS AND CONCLUSION: (1) There was no significant statistical difference in the displacement of the fracture 4 weeks after reduction between the Qiao’s spatial frame group and the Qiao’s spatial frame assisted reduction and unilateral external fixator fixation group (P > 0.05). (2) There was no significant statistical difference in the fracture healing time, lower extremity functional score and pin tract infection rate between the two groups (P > 0.05). (3) The pin tract traction pain in the Qiao’s spatial frame assisted reduction and unilateral external fixator fixation group was significantly reduced compared with the Qiao’s spatial frame group, with significant differences (15 cases versus 2 cases, P < 0.05). (4) It is indicated that Qiao’s spatial frame assisted reduction and unilateral external fixator fixation technology achieves anatomical reduction and stable fixation by coupling a Qiao’s spatial frame with a unilateral external fixator structure, significantly reducing the volume of traditional circular external fixators and reducing the incidence of needle tract complications, providing a minimally invasive and effective treatment option for closed and open tibial shaft fractures.

Key words: tibial shaft fracture, external fixator, digitalization, reduction, fixation
