Open Door Versus Double Door Laminoplasty in the Treatment of Cervical OPLL: A 10-Year Retrospective Analysis

Both laminoplasty methods were effective for long-term treatment of cervical OPLL, providing similar clinical outcomes and improvement in the JOA score over a 10-year follow-up period. However, the ROM decreased significantly more in the DD group than in the OD group, especially in patients younger than 50 years of age. These findings suggest that, although both techniques are viable options, patient age and preservation of cervical ROM may be important considerations in the choice of surgical method.
