Acute Myelopathy due to Ruptured HNP in Cervical OPLL Patient: Case Report

Abstract

Ossification of the posterior longitudinal ligament (OPLL) is an uncommon disorder that may be associated with slowly progressing neurological symptoms. We encountered a case of acute cervical myelopathy due to a ruptured disc in an asymptomatic patient with OPLL, who was surgically managed by the anterior approach and fusion. We report the case with a review of the relevant literature.

  Fig. 1. A sixty eight years old male visited our hospital with paresthesia of both hands and weakness of both upper and lower extrem-ities. Preoperative X-ray (A), 3-dimensional CT scan(B) and T2-weighted sagittal and axial MRI scan (C, D) reveal the severe cord compression due to ruptured disc of C4-5 and OPLL of C4-6. (A dotted line and a dotted arrow indicate the OPLL mass and a solid arrow indicates the ruptured disc at C4-5 level.)

• 

  Fig. 2. The patient underwent anterior discectomy of C4-5 with removal of huge free ruptured fragments. And corpectomy of C5 with careful removal of OPLL and iliac grafting with anterior ORION plate was performed. Postoperative X-ray (A) and T2-weighted sagittal MRI scan (B) show the markedly decompressed spinal cord.
