[Characteristic and surgical treatment of cervicothoracic spine fracture].

Objective: To discuss the clinical characteristic and surgical treatment of cervicothoracic spine fracture complicated with spine cord injury.

Methods: Thirty-eight patients with cervicothoracic fracture and spine cord injury were retrospectively analyzed from January 1998 to January 2007. There were 29 males and 9 females with an average age of 36.4 years ranging from 18 to 58 years. All patient suffered from pain and limitation of motion on cervicothoracic junction. According to American Spinal Injury Association (ASIA) grades, 4 cases were in grade A, 13 cases in grade B, 10 cases in grade C, 7 cases in grade D and 4 cases in grade E. All patients were treated with anterior decompressed, bone graft and Zephir plate fixation in cervicothoracic spine.

Results: All patients were followed up for 1 to 10 years, the mean followed up time was 4.5 years. And all patients got complete bone fusion within 4 to 6 months postoperatively. There were no pull-out and breakage of screws or plates. Spinal cord functional recovery improved on average 3.8 degree according AISA standard. Two patients appeared transient hoarse voice after surgery, the symptoms were alleviated from 3 to 6 months after operation. Seven patients were complicated with Horner syndrome preoperatively, and the symptoms were disappeared after operation.

Conclusion: The clinical situation of cervicothoracic spine fracture with spine cord injury is complicated. And anterior decompressed, bone graft and internal fixation performed on cervicothoracic spine fracture can achieve an efficient and safe clinical outcome.
