INFIX技术与外固定支架分别联合骶髂关节螺钉治疗Tile B型骨折的效果观察

Curative Effect of INFIX and External Fixator Combined with Sacroiliac Screw on Tile Type B Fracture

目的:探讨前环皮下内置外固定架(INFIX)技术与外固定支架分别联合骶髂关节螺钉治疗Tile B型骨折的效果。方法:回顾性分析2019年3月至2022年3月就诊于本院骨科的88例Tile B型骨折患者,其中47例给予INFIX技术+骶髂关节螺钉治疗(INFIX组),41例给予外固定支架+骶髂关节螺钉治疗(外固定支架组),比较两组手术时间、术中出血量、住院时间、术后负重时间、愈合时间、并发症发生率、Matta评分、Majeed评分以及术后1、3、6个月EQ-5D评分及VAS评分。结果:INFIX组住院时间及愈合时间均短于外固定支架组,并发症发生率低于外固定支架组(P<0.05);术后6个月,INFIX组Matta评分优良率(95.74%)高于外固定支架组(80.49%)(P<0.05);INFIX组性生活评分高于外固定支架组(P<0.05);EQ-5D评分及VAS评分组间、时间点及交互差异均有统计学意义(P<0.0001),术后1个月及术后3个月INFIX组EQ-5D评分均大于外固定支架组,术后1个月及术后3个月INFIX组VAS评分均小于外固定支架组(P<0.05)。结论:INFIX技术联合骶髂关节螺钉治疗Tile B型骨折临床疗效更好,恢复期短,更有利于患者进行早期功能性锻炼,且并发症发生率较低。

Objective:To explore the curative effect of internal fixation(INFIX)and external fixator combined with sacroiliac screw on Tile type B fracture.Methods:A total of 88 patients with Tile type B fracture admitted to Orthopedics Department of the hospital were retrospectively analyzed between March 2019 and March 2022,including 47 cases treated with INFIX and sacroiliac screws in INFIX group and 41 cases treated with external fixator and sacroiliac screws in external fixator group.The operation time,intraoperative blood loss,hospitalization time,postoperative weight-bearing time,healing time,incidence of complications,scores of Matta and Majeed,and scores of EQ-5D and VAS at 1,3 and 6 months after surgery were compared between the two groups.Results:The hospitalization time and healing time in INFIX group were shorter than those in external fixator group,and the incidence of complications was lower than that in external fixator group(P<0.05).At 6 months after surgery,good rate of Matta score in INFIX group was higher than that in external fixator group(95.74%vs 80.49%,P<0.05),and sex life score was higher than that in external fixator group(P<0.05).The differences in EQ-5D and VAS scores were statistically significant in different groups at different time points(P<0.0001).At 1 month and 3 months after surgery,EQ-5D score in INFIX group was higher than that in external fixator group,and VAS score was lower than that in external fixator group(P<0.05).Conclusion:The clinical curative effect of INFIX combined with sacroiliac screw is better on Tile type B fracture,with shorter recovery period.It is more conducive to early functional exercise,with low incidence of complications.
