To evaluate the efficacy and safety of total en bloc spondylectomy with autologous sternal structural graft, subaxial pedicle screws, and 5.5 mm titanium rods in primary bone tumor surgery.
From January 2019 to February 2020, two patients with lower cervical spine (C7) primary bone tumor underwent total en bloc spondylectomy, interbody fusion with sternal structural autograft, and posterior instrumentation using subaxial pedicle screws. The medical records and radiographic findings of the patients were reviewed.
C7 total en bloc spondylectomy was successfully performed; the anterior column was reconstructed with an autologous sternal structural graft with posterior instrumentation using subaxial pedicle screws and 5.5 mm titanium rods. After surgery, the VAS scores of neck and radiating arm pain in both patients were relieved considerably. Bony fusion was achieved in all patient by 6 months after surgery. There were no postoperative complications associated with the donor site.
Structural bone obtained from the sternum is safe and provides a viable alternative to cervical fusion for patients with primary bone tumor. It confers the advantages of autograft fusion without the complications associated with donor site morbidities.
评估全脊椎整块切除术联合自体胸骨结构性移植物、下颈椎椎弓根螺钉和 5.5mm 钛棒在原发性骨肿瘤手术中的疗效和安全性。
2019 年 1 月至 2020 年 2 月，2 例下颈椎（C7）原发性骨肿瘤患者接受了全脊椎整块切除术、胸骨结构性自体移植物椎间融合及下颈椎椎弓根螺钉后路内固定。回顾患者的病历和影像学资料。
成功完成 C7 全脊椎整块切除术，采用自体胸骨结构性移植物重建前柱，后路采用下颈椎椎弓根螺钉和 5.5mm 钛棒进行内固定。术后，2 例患者的颈痛和放射臂痛 VAS 评分均显著缓解。术后 6 个月所有患者均获得骨性融合。供区无术后并发症。
胸骨获取的结构性骨为原发性骨肿瘤患者的颈椎融合提供了一种安全且可行的选择，具有自体移植物融合的优势，同时避免了供区并发症。
