摘要

目的

探讨3D打印辅助改良Frosch入路手术在累及后外侧柱的Schatzker Ⅱ型胫骨平台骨折中的应用效果。

方法

选取2023年8月至2025年1月北京积水潭医院贵州医院收治的191例累及后外侧柱的Schatzker Ⅱ型胫骨平台骨折患者，按照随机数字表法分为观察组（96例）和对照组（95例）。观察组患者采用3D打印辅助改良Frosch入路手术，对照组患者采用传统前外侧入路手术。比较2组患者手术相关指标、手术前后美国特种外科医院（HSS）评分、步态参数及并发症发生情况和关节功能恢复情况。

结果

观察组患者手术时间、骨折愈合时间、术中透视次数短/少于对照组（

0.05）；2组患者术中失血量比较，差异无统计学意义（

0.05）。术后3个月，观察组患者HSS评分、步速、步频、膝关节活动度改善优于对照组（

0.05）。术后6个月，2组患者并发症发生率、关节功能恢复优良率比较，差异均无统计学意义（

0.05）。

结论

3D打印辅助改良Frosch入路治疗累及后外侧柱的Schatzker Ⅱ型胫骨平台骨折安全可靠，可缩短手术时间及骨折愈合时间，有利于患者术后早期功能恢复。

Abstract

Objective

To investigate the application effect of 3D‑printed assisted modified Frosch approach surgery in Schatzker type Ⅱ tibial plateau fractures involving the posterolateral column.

Methods

A total of 191 patients with Schatzker type Ⅱ tibial plateau fractures involving the posterolateral column， who were admitted to Beijing Jishuitan Hospital Guizhou Hospital from August 2023 to January 2025， were enrolled and randomly assigned to the observation group （96 cases） and the control group （95 cases） by random number table method.Patients in the observation group underwent surgery through the 3D‑printed assisted modified Frosch approach，while those in the control group received surgery through the conventional anterolateral approach. The two groups were compared in terms of the surgical‑related indicators， hospital for special surgery （HSS） score and gait parameters before and after surgery， and the occurrence of complications and joint function recovery.

Results

The patients in the observation group had shorter surgery time and fracture healing time， and fewer intraoperative fluoroscopies compared to the control group （

0.05）. The difference in intraoperative blood loss of patients between the two groups was not statistically significant （

0.05）. Three months after surgery， patients in the observation group showed better improvements in HSS scores， walking speed， step frequency， and knee range of motion than those in the control group （

0.05）. Six months after surgery， there were no significant differences in the incidence of complications or the excellent recovery rate of joint function between the two groups （

0.05）.

Conclusion

The 3D‑printed assisted modified Frosch approach is safe and reliable for the treatment of Schatzker type Ⅱ tibial plateau fractures involving the posterolateral column， which can shorten the surgery time and fracture healing time， and facilitate the early postoperative functional recovery.
