Clinical Characteristics and Surgical Outcome of Revision Surgery in Patients with Cervical Ossification of the Posterior Longitudinal Ligament

Clinical outcomes (Japanese Orthopaedic Association and visual analog scale scores) of revision surgery are similar to the outcomes of patients who did not require revision surgery. Residual stenosis after the index surgery is the most common indication for early revision surgery. To avoid early revision surgery, surgeons should carefully consider achieving circumferential decompression of the spinal canal during initial surgery.
