Intradural Cervical Disc Herniation

Abstract

Intradural cervical disc herniation is relatively rare, and the two additional cases updated the number of this condition to 29. It remains difficult to definitively diagnose the disease before surgery, but some indirect signs may indicate the cases. Corpectomy under a microscope as the first option in treatment of this disease is recommended once it is highly diagnosed. The pathogenesis of intradural cervical disc herniation remains to be further investigated. We presume that biochemical factors may play an important role in the pathogenesis.

Lever reduction using polyaxial screw and rod fixation system for the treatment of degenerative lumbar spondylolisthesis with spinal stenosis: technique and clinical outcome

“…Various reduction procedures have been described for lumbar spondylolisthesis. The surgical techniques, including translation reduction with double-threaded screws [19], distract and slip reduction [20], and insert-and-rotate posterior lumbar interbody fusion technique [8,13,21-26] have been reported in the literature. Using a posterior-only approach, the above-described technique could yield substantial deformity correction.…”

Spontaneous Cervical Intradural Disc Herniation Associated with Ossification of Posterior Longitudinal Ligament

“…Pan et al stated that preoperative CT scan of cervical spine is undoubtedly important and necessary in the treatment of the cervical disease, especially in exclusion of presence of OPLL, and that it was a pity that CT scan was not taken at that time in the two cases described in his article [7]. The authors agree with this.…”

“…It has been theorized that degeneration of the nucleus pulposus causes secretion of increased amounts of inflammatory substances. These substances are a “foreign body” in the spinal canal, and autoimmunoreactivity will be activated [7]. We agree that biochemical factors may play an important role in the pathogenesis.…”

“…The true incidence of this condition is not known. Tables listing previous case reports have been published by Kansal et al (25 cases) and also by Pan et al (27 cases) [6, 7]. Warade listed just 23 reported cases in a paper published in 2014 [8].…”

“…Pan et al noted that adhesion between ligaments and dura was often observed in case reports of intradural disc herniations [7]. In the patient reported by Hsieh et al, the hypertrophic PLL was tightly adhered to the dura mater [2].…”
