Clinical application of digital six-axis external fixator reduction combined with locking external fixator based on CT data in the treatment of tibial shaft fractures
Objective:To explore the reduction accuracy and fixation effectiveness of digital six-axis external fixator reduction and locking external fixator based on CT data in the treatment of tibial shaft fractures. Methods:A retrospective analysis was conducted on the clinical data of 52 patients with tibial shaft fractures treated with digital six-axis external fixator reduction combined with locking external fixator based on CT data at the Honghui Hospital Affiliated to Xi'an Jiaotong University from October 2021 to April 2023. Forty males and 12 females were included,with an average age of 38.0±12.9 years (range:16-71 years). According to the AO classification,there were 21 cases of type A,19 cases of type B,and 12 cases of type C. There were 16 cases of open fractures and 36 cases of closed fractures. Preoperative and postoperative fracture displacement and angulation in the coronal and sagittal planes,as well as axial displacement were measured and compared. Lower extremity function was assessed using the lower extremity functional score (LEFS). Results:Fifty-two patients were followed up for 12 to 36 months,with an average of (27.1±13.1) months. Postoperatively,displacement and angulation in the coronal and sagittal planes,and axial displacement were 0.0(0.0,1.4) mm and 0.0°(0.0°,0.0°),0.0(0.0,1.5) mm and 0.0°(0.0°,1.5°),and 0.3(0.0,1.9) mm,respectively. All of these values were significantly lower than the preoperative values of 7.9(4.7,13.3) mm and 3.5°(1.5°,6.8°),4.7(2.5,8.5) mm and 4.0°(1.5°,7.2°),and 5.6(3.3,10.0)mm,respectively (all P<0.001). All fractures achieved satisfactory reduction. The fracture healing time ranged from 12 to 38 weeks,with an average of (24.2±6.4) weeks. The LEFS ranged from 51 to 80 points,with an average of (75.3±5.6) points. Conclusions:The digital six-axis external fixator based on CT data demonstrates satisfactory reduction outcomes,. The locking external fixator provides secure fixation with minimal impact on patient's daily life. The combination of these two methods in the treatment of tibial shaft fractures has the advantages of simple operation,precise reduction,firm fixation,minimal trauma,and rapid recovery. This approach aligns with the principle of accelerated recovery surgery and is worth promoting in clinical practice.
