Objective: To treat injury of the lower cervical spine C_6 to C_7 with cervical lateral mass plates and T_1 pedicle screws through posterior approach. Methods: The data of 8 patients with lower cervical spine C_6 or C,_7 injury (6 patients with fracture and dislocation in C_6 and C_7 and 2 with fracture in C_7) were analyzed retrospectively in this study. For the preoperative American Spinal Injury Association (ASIA) classification, Grade C was found in 3 cases and Grade D in 5 cases. Screws were placed on the lateral masses and the first thoracic pedicle with Margerl technique. Lamina or facet bone allografting was used to achieve a long-term stability. Results: All the 8 patients were followed up for 5-37 months (mean: 15 months). No operative death occurred. There were no examples of aggravation of spinal cord injury or vertebral artery injury, cerebrospinal fluid leak, nerve roots injury, screw malposition or back-out, loose of alignment or implant failure. Clinical symptoms and ASIA classification were improved in all the patients. Postoperative MRI scanning confirmed the satisfactory screw placement in all the cases. Conclusions: Lateral mass plates and pedicle screws through posterior approach are safe and beneficial for patients with lower cervical spine C_6 or C_7 injury.
