Anchor fixation in posterior surgery for cervical spinal canal stenosis combined with cerebral infarction shows less effect on the cerebral circulation / 中国组织工程研究

ABSTRACT

BACKGROUND:There is a high risk for the elderly cervical spine surgery combined with cerebral infarction, whereas conservative treatment is often unable to resolve serious cervical lesions. OBJECTIVE:To discuss the surgical effects of anchor fixation via posterior approach on cervical spinal canal stenosis combined with cerebral infarction. METHODS:A total of 21 patients with cervical spinal canal stenosis combined with cerebral infarction who were admitted over the past 5 years accepted cervical posterior expensive open-door laminoplasty and fixation with wire anchors. Therapeutic effects were evaluated according to the Japanese Orthopaedic Association (JOA) scores. RESULTS AND CONCLUSION:Al the patients were fol owed up 6 to 24 months, averagely 15 months. Al patients were smoothly through the perioperative period. There were no acute severe cerebral infarction cases. Preoperative JOA score was (7.6±2.0) points averagely, and postoperative JOA score was (13.3±1.8) points averagely, showing a significant difference (P<0.01). Of the 21 patients, excellent effects were in 11 cases and good in 7 cases. The effective rate was 95%(20/21), and the excellent-good rate was 86%(18/21). The risk of surgical treatment of patients with cerebral infarction is higher, but it is not the absolute contraindication. Choosing the proper operation way is highly important. Cervical posterior expensive open-door laminoplasty and fixation with wire anchors can be used to reduce the risk of cerebrovascular accidents to some extent, and obtain an excellent clinical effect.
