Symptomatic postoperative spinal epidural hematoma preferentially occurs after anterior cervical discectomy and fusion versus anterior cervical corpectomy and fusion: a retrospective study.

What Researchers Did

Researchers retrospectively reviewed 551 patients who underwent either anterior cervical discectomy and fusion (ACDF) or anterior cervical corpectomy and fusion (ACCF) for 2-level cervical spondylotic myelopathy (CSM) to compare the incidence and outcomes of symptomatic postoperative spinal epidural hematoma (SPSEH).

What They Found

The study found that symptomatic postoperative spinal epidural hematoma (SPSEH) preferentially occurred after anterior cervical discectomy and fusion (ACDF) compared to anterior cervical corpectomy and fusion (ACCF). Blood loss was significantly different between the two groups (P<0.001), though other preoperative and perioperative indexes showed no significant differences.

Canadian Relevance

This study has no direct Canadian connection as it was not conducted in Canada or with Canadian participants.

Study Limitations

A key limitation of this study is its retrospective design, which may introduce selection bias and limit the generalizability of the findings.
