Objective To investigate the therapeutic effectof the modified anterior approach in treatment of the patients with cervicothoracic junction spinal lesions. Methods From September 2000 to January 2005, 23 patients (15 males, 8 females) with spinal lesions in the cervicothoracic junction underwent a standard cervical approach, which was combined with apartial median steotomy and transverse steotomy through the synostosis between the manubrium and body of the sternum to expose the lesion adequately. Among thepatients, 3 had fracture, 7 had dislocation, 6 had tuberculosis, and 7 had tumor. The pathologic change regions was as follows: 2 in the C6-T1 segment, 2in the C6-T2 segment, 3 in the C7-T1 segment, 3 in the T3 segment, 8 in the T1 segment, and 5 in the T2egment. The classification of Frankel were as follows: 2 at grade A, 4 at grade B, 7 at grade C, 4 at grade D, and 6 at grade E. All the patients underwent a radical excision of the affected spinal bone, were given a proper tricortical iliac crest and anterior instrumentation to reconstruct the anterior spinal column, followed by immobilization in a brace for 3-6 months. Results The mean followup period was 30 months (range, 1042 months). Bony fusion was obtained in all the patients.One patient died of pulmonary cancer metastasis 10 months after operation. The nerve function of the spinal cord recovered at different degrees (1 at grade A, None at grade B, 2 at grade C, 10 at grade D, 10 at grade E). Conclusion Ourmodified anterior approach can provide a direct and safe access to the lesions in the region.
【摘要】 目的 探讨CT引导下经椎弓根穿刺活检对椎体病变的诊断价值及可行性。 方法 回顾性分析2009年5月—2010年4月42例椎体病变患者经椎弓根穿刺活检的穿刺活检方法、病理结果、最终诊断及穿刺并发症。 结果 患者总穿刺准确率为95.2%（40/42）。其中恶性病变的穿刺准确率为94.3%（33/35），良性病变穿刺准确率为100%（7/7）；所有患者均未发生严重穿刺并发症。 结论 CT引导下经椎弓根穿刺活检诊断椎体病变有安全可靠、准确性高等特点。【Abstract】 Objective To explore the value and the feasibility of CT guided transpedicular biopsy in diagnosing vertebral body lesions. Methods From May 2009 to April 2010, 42 patients with vertebral body lesions underwent CT guided transpedicular biopsy. The clinical data including the puncture method, pahtological resutls, final diagnosis, and the pucture complications were retrospectively analyzed. Results The total accuracy rate of the puncture was 95.2%(40/42). The accuracy rate of the puncture was 94.3% (33/35) for malignant lesions and 100.0% (7/7) for benign lesions. No complication occurred. Conclusion CT guided transpedicular biopsy is very helpful in diagnosing vertebral body lesions with high accuracy and fewer complications.
