ABSTRACT
BACKGROUND:
The aim of this study was to compare the clinical efficacy and radiological outcomes of skip corpectomy and fusion (SCF) with anterior controllable antedisplacement and fusion (ACAF) for treating multilevel ossification of the posterior longitudinal ligament (OPLL).METHODS:
62 patients with multilevel OPLL who had undergone SCF or ACAF were analyzed retrospectively. Types of OPLL, occupying ratio (OR), Japanese Orthopaedic Association (JOA) score, Recovery Rate (RR), Neck Disability Index (NDI) score, Cobb's angles of C2-C7, operation time, blood loss, hospital stay, ratings for fusion assessment and complications were recorded and assessed.RESULTS:
Postoperative C2-C7 Cobb's angle (11.1 ± 3.2° vs. 13.7 ± 2.5°; P < 0.05), NDI scores at final follow-up (14.3 ± 1.6 vs. 13.3 ± 1.3; P < 0.05), and rate of cerebral fluid (CSF) leakage (5, 16.7% vs. 0,0%; P < 0.05) were significantly better in the ACAF group. At 6 months, bone graft fusion rate was significantly greater in the ACAF group (24.75% vs. 15.50%; P < 0.05).CONCLUSIONS:
Surgical treatment of multilevel OPLL by SCF or ACAF showed no significant differences in clinical outcomes, with the exception of better NDI scores at final follow-up in ACAF. In addition, ACAF is better than SCF in terms of early bone graft fusion rate, lordotic curvature improvement, risk of CSF leakage.Palabras clave
