The purpose is to evaluate the efficacy of tranexamic acid in cervical laminoplasty; the surgical procedure used was identical in all cases.

Tranexamic acid, an inhibitor of fibrinolysis, has proven to be effective in reducing perioperative blood loss in patients undergoing total hip and knee arthroplasty. However, limited numbers of well-controlled trials in spinal surgery have been conducted due to heterogeneity in the performed surgical procedures.

Inclusion Criteria:

• Patients who were scheduled to undergo cervical laminoplasty from C3 to C6 for cervical multilevel compressive myelopathy with a narrow spinal canal for which nonoperative therapy had failed.

Exclusion Criteria:

• Patients with chronic renal failure, cirrhosis of the liver, serious cardiac disease, allergy to TXA, a history of thromboembolic disease, and bleeding disorders, as well as those who were currently receiving antiplatelet and/or anticoagulant drugs, were excluded from this study.
