ABSTRACT
<p><b>OBJECTIVE</b>To explore the clinical efficacy of unilateral open-door laminoplasty combined with foraminotomy for cervical ossification of posterior longitudinal ligament(OPLL).</p><p><b>METHODS</b>The clinical data of 45 patients with OPLL underwent surgical treatment between September 2011 and September 2015 were retrospectively analyzed. There were 26 males and 19 females with a mean age of 53.6 years old(ranged from 28 to 71 years). Among them, 24 cases received the surgery of unilateral open-door cervical laminoplasty combined with foraminotomy(combined group), and 21 cases received a single unilateral open-door cervical laminoplasty(single group). Operation time, intraoperative blood loss, complications including C₅ nerve root palsy and axial symptoms were compared between two groups. Pre-and post-operative Japanese Orthopedic Association(JOA) score, improvement rate of neurological function, Neck Disability Index(NDI) score, and cervical Cobb angle were recorded and analyzed between the two groups.</p><p><b>RESULTS</b>All the patients were followed up for 12-24 months, with an average of (14.3±2.8) months for combined groups and (13.7±3.1) months for single group, and no significant difference was found between the two groups(>0.05). There was no significant difference in operation time and intraoperative blood loss between two groups(>0.05). Postoperative JOA scores obtained obvious improvement in all patients(<0.05). However, there was no significant difference between two groups for the improvement rate of neurological function(>0.05). At final follow-up, NDI scores of combined group and single group were 13.6±1.8 and 16.1±2.4 respectively, there was significant difference between two groups(<0.05). The incidence of C₅ nerve root palsy was lower in combined group(4.2%) than that of single group (28.6%). There was no significant difference in incidence rate of axial symptoms between two groups(>0.05). There was no significant difference in cervical Cobb angle between pre-and post-operative conditions, or between two groups(>0.05).</p><p><b>CONCLUSIONS</b>Unilateral open-door cervical laminoplasty combined with foraminotomy is an effective method to treat cervical OPLL, which could provide sufficient decompression of spinal cord and nerve root, prevent the C₅ nerve root palsy.</p>
