OBJECTIVE: To evaluate the effect of staged surgical treatment on central cord syndrome of the cervical spine.
METHODS: A retrospective analysis was conducted in 36 cases of central cord syndrome of the cervical spine treated with staged surgery. The patients (aged 50 to 79 years, mean 56.9 years) were divided into group A (50 to 64 years old, n=20) and group B (above 65 years old, n=16), and each group was further divided into 2 subgroups according to the range of decompression in the second stage, namely A1, B1 and A2, B2. ASIA motor score (AMS) was analyzed before the first-stage surgery, before the second-stage surgery and at the last follow-up after the second-stage surgery.
RESULTS: All the surgeries were performed successfully. The patients were followed up for 12 to 32 months (mean 18.4 months) after the second-stage surgery. After the first-stage surgery, the AMS was 75.8-/+14.6 in group A, 73.2-/+13.1 in group B, 78.5-/+10.2 in group A1, 76.8-/+9.5 in group A2, 72.2-/+12.6 in group B1 and 77.4-/+18.3 in group B2. The AMS at the last follow-up was 90.7-/+10.5 in group A, 89.5-/+12.4 in group B, 91.3-/+13.2 in group A1, 90.7-/+14.8 in group A2, 88.5-/+11.2 in group B1 and 92.4-/+13.6 in group B2. There was no significant difference between groups A and B or between the subgroups A1 and A2 and groups B1 and group B2. The AMS was 75.8-/+14.6 after the first-stage surgery and 90.7-/+10.5 at the last follow-up in group A, significantly higher than those in group B (73.2-/+13.1 and 89.5-/+12.4, respectively, P<0.05).
CONCLUSION: Staged surgery is effective for treatment of central cord syndrome of the cervical spine, and the effect of the surgery is not related to the patients’ age or the range of decompression.
