The cervicothoracic junction (CTJ) presents a surgical challenge due to its transitional nature from mobile to rigid segments. Therefore, the biomechanical characteristics of this transitional zone must be taken into consideration during instrumentation. This study aimed to determine the efficacy of the cervical pedicle screw placement (CPS) combined with 5.5-mm single-diameter rods in treating various challenging diseases at the CTJ. From March 2018 to February 2022, a total of 42 patients (male = 25; female = 17) underwent posterior cervical spinal surgery crossing the CTJ with or without an anterior approach by a single surgeon. The mean patient age was 58.6 years (range, 16-81 years). In all the included cohorts, only the Legacy® pedicle screw system (Medtronic Sofamor Danek, Inc., Memphis, TN, USA) was used for the placement of pedicle screws on the cervical and thoracic vertebrae at the CTJ. This study describes the detailed indications and results of the treatment for 5 disease categories. CPS combined with 5.5-mm single-diameter rods provides biomechanical stability for the treatment of challenging conditions, such as trauma, benign or malignant tumors, or deformities in the CTJ.
由于颈胸交界处（CTJ）具有从活动节段到刚性节段的过渡性质，因此该部位的手术具有挑战性。因此，在进行器械植入时必须考虑这个过渡区域的生物力学特性。本研究旨在确定颈椎椎弓根螺钉置入术（CPS）联合5.5毫米单直径棒治疗CTJ处各种具有挑战性疾病的疗效。2018年3月至2022年2月，共有42例患者（男性25例；女性17例）接受了由单一外科医生进行的跨越CTJ的后路颈椎手术，部分患者同时进行了前路手术。患者平均年龄为58.6岁（范围16 - 81岁）。在所有纳入的队列中，仅使用Legacy®椎弓根螺钉系统（美国美敦力索法玛·丹纳公司，田纳西州孟菲斯）在CTJ处的颈椎和胸椎上置入椎弓根螺钉。本研究描述了5种疾病类型的详细治疗适应证和结果。CPS联合5.5毫米单直径棒为治疗CTJ处的创伤、良性或恶性肿瘤、畸形等具有挑战性的病症提供了生物力学稳定性。
