Surgical outcomes of cervical myelopathy due to ossification of posterior longitudinal ligament: Anterior decompression and fusion versus posterior laminoplasty.
J Orthop Surg (Hong Kong). 2019 May-Aug; 27(2):2309499019837907.JO

Abstract

BACKGROUND

The purpose of this study was to compare the surgical outcomes of anterior decompression and fusion (ADF) with that of posterior laminoplasty (LAMP) for cervical myelopathy caused by ossification of posterior longitudinal ligament (OPLL).

METHODS

We retrospectively assessed the medical records of patients who underwent surgery for cervical myelopathy owing to OPLL between 2007 and 2016 at our institution. Fifty patients were included in this study, including 17 patients in ADF group and 33 patients in LAMP group. Surgical outcomes were assessed under the Japanese Orthopaedic Association (JOA) score. The radiologic and clinical data were compared between two groups.

RESULTS

There was no significant difference in age, follow-up time, operation time, blood loss, length of stay, preoperative JOA score, occupying ratio of OPLL, diameter of spinal canal, preoperative and final follow-up C2-C7 Cobb angles, and the change of C2-C7 Cobb angle before and after operation between ADF and LAMP groups. The final follow-up JOA score and the neurological recovery rate were significantly higher in ADF group than in LAMP group, particularly in patients with segmental-type OPLL. Cerebrospinal fluid leakage is a major complication after ADF, C5 paralysis, and axial pain frequently results from LAMP.

CONCLUSION

Compared with LAMP, ADF shows better improvement of neurological function in patients with cervical myelopathy due to OPLL, especially in patients with segmental-type cervical OPLL.
