Abstract：Objective To observe the clinical effects of anterior floating decompression and internal fixation in treat-ment of isolated cervical ossification of posterior longitudinal ligament ( OPLL) .Methods A total of 36 cases of cervical OPLL patients in isolated type accepted the procedure of anterior floating decompression combined with titanium mesh im-plant and internal fixation.The cervical curvature index ( CCI) , postoperative neurological recovery and complications were recorded and analyzed.Results The operation was successful in all patients, and no aggravation of neurological symptoms and spinal cord injury were found after the surgery.The operative time was 81-155 ( mean 116.0 ±21.3) min with a blood loss of 190-410 (mean 227.0 ±35.5) mL.Five cases of cerebrospinal fluid leakage occurred after the surgery, and healed well after local compression and lumbar catheter drainage.During the follow-up of 15-46 months, no internal fixation loose-ness, dislocation and extrusion happened.The Japanese Orthopedic Association (JOA) scale was improved form (8.5 ± 2.1) preoperatively to (13.0 ±3.3) three months after surgery, and (13.7 ±3.6) at the final follow-up; significant difference was found between that before and after operation (all P<0.05).The neurological recovery rate was (70.1 ± 13.8)%.The CCI was 14.2% ±4.3%before operation, 13.8%±4.6%three days after surgery, and 12.9%±4.4%at the final follow-up, and no statistical difference was found between them.Conclusion Anterior floating decompression and internal fixation in treatment of isolated cervical OPLL could completely remove the bony compression directly and re-store the physiological curvature, and it has good effect.
