Cervicothoracic junction disc herniation: Our experience, technical remarks, and outcome

摘要

Background: C7-D1 disc herniation is rare in comparison with other cervical levels. The incidence rates are between 3.5% and 8%. The cervicothoracic junction disc herniation can be operated posteriorly or anteriorly. The anterior approach can be challenging because of the difficulty of access resulted from the manubrium. In this article, we present our experience about cervicothoracic junction disc herniation (C7-T1) surgery. Materials and Methods: Between January 2008 and December 2017, 21 patients have been operated for solitary C7-T1 disc herniation. We operated 12 male patients and 9 female patients. Eight patients have been operated by the anterior approach, and 13 patients underwent surgery by the posterior approach. The mean symptoms duration was 11.4 months. Results: All patients had C8 cervicobrachial neuralgia. Other clinical presentations were numbness, tingling sensation, and weakness. All patients improved after surgery. We had no significant complication. Conclusion: We did not find a great difference between the clinical features of cervicothoracic herniated disc and other cervical levels. The anterior approach seems more difficult to carry out in particularly in large patients with the short neck. The posterior approach can be used for all types of patients except in the case of medial disc herniation.
