Abstract:
Objective To evaluate the surgical outcomes of anterior controllable anteriodisplacement and fusion (ACAF) for the reoperation of the cervical ossification of posterior longitudinal ligament (OPLL). Methods Twelve cervical OPLL patients aged 52-74 (63.92±6.54) years, who had poor curative effect or aggravated symptoms after posterior decompressive surgery, were included in this study, with 7 males and 5 females. All patients underwent reoperation with ACAF between Feb. 2016 and Feb. 2017. The Japanese Orthopaedic Association (JOA) score and visual analogue scale (VAS) were used to evaluate neurological function and pain preoperatively and 3, 6, 12 months postoperatively and at final follow-up. Results The patients were followed up for 9-21 months (average [14.92±3.75] months). The neurological function was recovered to varying degrees after ACAF in all patients. The JOA score was significantly improved from 9.33±1.93 preoperatively to 14.67±2.01 at final follow-up (t=3.184, P<0.05), and the neurological function recovery rate was (71.9±21.8)%. The VAS score was significantly decreased from 5.25±1.42 preoperatively to 0.92±0.83 at final followup (t=4.025, P<0.05). Conclusion The outcomes of ACAF for the reoperation of cervical OPLL are satisfactory. ACAF significantly improves the patients' neurological function, and it is an alternative surgical treatment of the reoperation for cervical OPLL.
