Calcified Posterior Longitudinal Ligament

Abstract

|
|
The calcified posterior longitudinal ligament became a definite clinicopathological entity causing cervical cord or root compression. It has typical roentgenographic findings of abnormal longitudinal strip of calcification along the posterior margin of vertebral bodies. As a rule, it ensues the narrow spinal canal and cervical myelopathy. Cases of calcified posterior longitudinal ligament with or without cervical myelopathy were reported in 28 or more Japanese and later, in nine Caucasians and a negro in America, and in two Australians.
A report is presented on a patient in whom roentgenograms of cervical spine appeared identical to those described by many previous authors.
Park JO, a 62-year-old Korean man had a history of dull and heavy sensation in the neck. and right shoulder for about one and half month duration. One week prior to admission, he began to suffer from pain in the neck and right suprascapular region radiating down to the right shoulder, upper arm, and the elbow.
Neurological examination revealed numbness to light touch on the area of C 4 and C 5 dermatomes on the right side. Other neurological signs were quite normal including the neck motion, motor function, sensation to pin prick stimuli, and deep tendon reflexes. Simple cervical spine roentgenograms showed a strip of bony density on the posterior margin of C 2 to C 4 vertebral bodies. The sagittal diameter of the calcified strip at C 4 was 7 mm. On right sided oblique view, the intervertebral foramina of C 3-4 and C4-5 were found encroached upon by a strip of calcific deposits. Cervical myelogram revealed widened transverse diameter of the spinal cord at the level of C 3 to C 4 vertebrae on anteroposterior projection, and ventrally indented filling defects of the contrast medium at the same level on translatral view. Decompressive total laminectomy along with partial facetectomy has been thought to be treatment of choice by many reporters.
In this patient, operation was not performed due to tolerability to pain by symptomatic treatment and to minimal neurological deficit.
