摘要Cervicothoracic spine is a special position in the anatomy andbiomechanics. The anterior includes a variety of tissues, organs and nerves. And the lesion gets deeper owing to the chest. In addition, the concentrated spinal stress makes a high risk of failure of the internal fixation. So, surgical treatment is of great difficulty for primary malignant tumors at the cervicothoracic junction. There are many disputes in the surgical approach for the cervicothoracic tumors. The proximal C7-T1 lesions can obtain a clear exposure by an anterior low suprasternal approach alone. On the contrary, access to the distal T2-4 lesions through an anterior approach is generally considered to be dififcult and need to becombined with sternotomy or thoracotomy. But the single posterior total spondylectomy can avoid large injury and severe complications caused by the anterior approach. Total spondylectomy can make spinal tumors reach the wide or marginal excision. In recent years, total spondylectomy is being widely used in the treatment of spinal primary malignant tumors, which is helpful to complete removal of the tumor and effective decrease of the local recurrence. Cervicothoracic junction changes from the lordosis and active cervical to kyphosis and relatively ifxed thoracic vertebrae. It is also a signiifcant change for vertebral morphology and spinal stress. For this reason, in the spinal reconstruction, the form and stress of the internal ifxation have a certain speciifcity. This article reviewed the progress of surgical treatment and spinal reconstruction for cervicothoracic primary malignant tumors. 颈胸段脊柱( cervicothoracic junction,CTJ )向上连接颈椎,向下延续胸椎,是脊柱的一个特殊部位,多指 C7~ T4[1-3]。CTJ 周围有复杂、重要的组织结构,如大动静脉(主动脉、腔静脉等)、重要器官(肺脏、气管、食管、胸导管等)、神经结构(神经根、喉返神经等)、骨性结构(胸骨、锁骨等);在生物力学上,由前凸的颈椎过渡到后凸的胸椎,造成此处应力集中[4]。CTJ 恶性肿瘤相对少见[5],当肿瘤对脊椎的骨性结构造成破坏时,容易出现脊柱不稳定和后凸畸形,损伤神经和脊髓,出现严重疼痛、不全截瘫甚至全瘫。CTJ 前方有胸腔,部位较深,显露困难,是外科手术技术的难点。笔者就 CTJ 原发恶性肿瘤的外科手术治疗、脊柱重建方面进行综述。
