Radical resection is the first-line option in managing cervical primary chondrosarcoma. Favorable anterior reconstruction is challenging after multilevel total spondylectomy in the cervical spine.
To illustrate the application of piezoelectric surgery and three-dimensional (3D) printing techniques in spine surgery.
A 27-yr-old patient was referred to our center with complaints of nocturnal neck pain and right upper extremity weakness. A 2-stage radical tumor resection was conducted using piezoelectric surgery with pathologically tumor-free margins. A 3D-printed titanium microporous prosthesis (3D-PTMP) was designed to reconstruct the anterior column of the cervical spine between C1 and T1 for stability.
The whole intraoperative blood loss was 2300 mL over the 2 procedures. The patient had an uneventful recovery, regaining ambulatory status 3 wk after the 2 operations without ventilator support or other severe complications. By the final 14-mo follow-up, the patient had achieved marked pain relief and favorable neurological improvement; a postoperative computed tomography scan indicated a good position of the 3D-printed construct between the endplates with no sign of tumor recurrence or implant subsidence.
The applications of piezosurgery in total spondylectomy and in 3D-PTMP in reconstruction can be a favorable alternative for managing multilevel cervical spinal tumors. Further studies are warranted to validate this surgical strategy.
根治性切除术是治疗颈椎原发性软骨肉瘤的首选方案。在颈椎多节段全脊椎切除术后,进行有利的前路重建具有挑战性。
阐述了在脊柱外科中应用压电骨刀和三维(3D)打印技术。
一位 27 岁的患者因夜间颈部疼痛和右上肢无力就诊于我院。采用压电骨刀进行 2 期根治性肿瘤切除术,实现了无肿瘤边界的肿瘤全切除。设计了 3D 打印钛微孔假体(3D-PTMP)以在 C1 至 T1 之间重建颈椎前柱的稳定性。
2 次手术的总失血量为 2300 毫升。患者术后恢复顺利,2 次手术后 3 周即可步行,无需呼吸机支持或其他严重并发症。在最终的 14 个月随访中,患者疼痛明显缓解,神经功能得到良好改善;术后 CT 扫描显示 3D 打印结构在终板之间位置良好,无肿瘤复发或植入物下沉迹象。
压电骨刀在全脊椎切除术中的应用以及 3D-PTMP 在重建中的应用,可为治疗多节段颈椎肿瘤提供一种有利的选择。需要进一步的研究来验证这种手术策略。
