Study design:

Cohort study 

研究目的:

通过前瞻性多中心临床队列研究证明在感染性骨缺损的重建方式中,骨搬移结合锁定钢板(bone transport with locking plate, BTLP) 技术在骨愈合率方面非劣于采用外固定装置缓慢牵拉成骨的传统骨搬运(bone transport, BT)技术,同时并发症发生率和健康相关生活质量优于BT技术  

Objectives of Study:

To demonstrate, through a prospective multicenter clinical cohort study, that in the reconstruction of infected bone defects, the Bone Transport combined with Locking Plate (BTLP) technique is non-inferior to the traditional Bone Transport (BT) technique using external fixation for gradual distraction osteogenesis in terms of bone healing rate. Furthermore, the study aims to show that BTLP is superior to BT in terms of complication rate and health-related quality of life .

Inclusion criteria

1.Aged 18 to 65 years, regardless of gender. 2.Confirmed diagnosis of femoral or tibial bone infection. 3.Willing to undergo a two-stage treatment protocol (Stage I: debridement and bone cement spacer implantation; Stage II: bone defect reconstruction), with effective infection control confirmed after Stage I debridement. 4.Patients selecting the bone transport technique for bone defect reconstruction in Stage II.
