Abstract:[Objective]:To investigate?surgical?strategy? for old?dislocation?of the subaxial?cervical spine.[Methods]: the clinical data of 11 patients with old?dislocation?of the subaxial?cervical spine who received surgical treatment in our department were collected and analyzed retrospectively.There were 7 males and 4 females.Among them, the C4/5 segment was affected in 3, the C5/6 segment in 4, the C6/7 segment in 3 and the C7S1segment in 1. which were all classified as DF(Distractive flexion)injuries , 3 cases were stage2 and 8 cases were stage3.The average interval from time of injury to operation was 5.8 months (range, 3–11months). ASIA grade: 2 cases were grade C, 5 cases grade D and 4 cases grade E;VAS score of neck pain: 0 score in 2 cases, 1 score in 2 cases, 5 score in 4 cases, 6 score in 3 cases. local kyphosis Angle was 26-45°, with an average of 38°.For one patient, CT showed that the dislocated vertebrae had a bony connection with the lower vertebrae in the anterior edge, the lower vertebral ACCF was performed for this case.Due to the poor soft tissue condition in the front of cervical spine , 1 patient underwent posterior lateral mass nail fixation and bone graft fusion.Skull traction was performed in 9 cases,the traction weight was 5-8kg, and the traction time was 3- 6 days.Among them, there were no reduction in 4 cases.A posterior procedure was conducted first, comprised of soft tissue release and facetectomy . Subsequent ACDF was performed.Partial reduction in 5 cases, and ACDF was conducted only .[Results]: The follow-up period was 16-28 months. At the last follow-up, all patients had bone graft fusion.and the ASIA grade was restored from C to D in 2 patients,D to E in 2 patients , and unchanged in 3 patients of grade D.VAS score for neck pain: 0 score in 5 patients, 1 score in 6 patients. Local kyphosis -6 ° -12 °, average 4 °.[Conclusion]: The incidence of old?dislocation?of the subaxial?cervical spine is low.Patients often have increasing symptoms of neurological damage or neck pain, which requires surgical treatment. Individualized surgical procedures can reduce surgical trauma and achieve good clinical results.
