Brief summary
The incidence and correlation of symptomatic epidural hematomas after cervical spine surgery was reviewed and analyzed, then it will provide reference to avoid the occurrence of this complication for the future clinical work.
Detailed description
43 patients with symptomatic epidural hematoma after cervical spine surgery were enrolled in the Peking University Third hospital from January, 2009 to February, 2017. 86 patients without symptomatic epidural hematoma after cervical spine surgery during the same period were randomly selected as the control group. Demographic information (including gender, age, previous history, smoking history, etc.)，disease parameters (diagnosis, mJOA(modified Japanese Orthopaedics association) score, NDI(neck disability index) score)，laboratory and imaging parameters (including platelet, coagulation function, albumin, and OPLL)，segments，treatment parameters (surgical method, number of surgical segments, operative time, intraoperative blood loss, anesthesia time, whether to use implants) and postoperative conditions (including the time of hematoma occurrence, diagnostic method, emergency debridement operation time, patient improvement before and after debridement) were collected.Firstly, risk factors for symptomatic epidural hematoma after cervical surgery were selected by univariate analysis,then independent risk factors were screened by multiple Logistic regression analysis.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| VAS(visual analogue pain scale) | 3 months after surgery | visual analogue pain scale, to evaluate patients' pain, form 0 to 10. more scores means more pain |
| Frankel score | 3 months after surgery | Postoperative Neurological Function，From A to E. Score A means complete paralyzed and E means no paralyzed |
| mJOA | 3 months after surgery | Postoperative Neurological Function, modified Japanese orthopaedics association, From 0 to 17 scores. More scores mean better recovery after surgery. Score 0 means the most severe symptoms. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| whether patients occur hematoma after surgery | From post operation immediately till 3 months after surgery | whether patients occur hematoma after surgery |
| postoperative neurological recovery after treatment of hematoma | From post operation immediately till 3 months after surgery | To record neurological recovery after treatment of hematoma from post operation immediately till 3 months after surgery, use modified Japanese Orthopaedics association |
| whether patients need emergency debridement | From post operation immediately till 3 months after surgery | whether patients need emergency debridement caused by hematoma |
| the place that occur hematoma | From post operation immediately till 3 months after surgery | the place that occur hematoma, to locate the place of hematoma from post operation immediately till 3 months after surgery |
