Utility of Discography as a Preoperative Diagnostic Tool for Intradural Lumbar Disc Herniation
Tomiya Matsumoto,Hiromitsu Toyoda,Hidetomi Terai,Sho Dohzono,Yusuke Hori,Hiroaki Nakamura 대한척추외과학회 2016 Asian Spine Journal Vol.10 No.4
Preoperative definitive diagnosis of intradural lumbar disc herniation (ILDH) is difficult despite the availability of various neuroradiological investigative tools. We present a case of ILDH diagnosed preoperatively by discography and computed tomography-discography (disco-CT).The patient was a 63-year-old man with acute excruciating right leg pain. Discography and disco-CT demonstrated leakage of the contrast medium into the intradural space. Based on these findings, a right L5 nerve root disturbance caused by ILDH was diagnosed. A right L5 hemi-laminectomy and a dorsal durotomy were performed. The herniated disc was carefully dissected and then completely removed. Three months after surgery, the patient had fully recovered. This report highlights the importance of making a definitive diagnosis of ILDH preoperatively for better surgical planning and improved clinical outcomes. Furthermore, discography and disco-CT are both useful preoperative diagnostic tools for the diagnosis of ILDH.

Prevalence of Diffuse Idiopathic Skeletal Hyperostosis in Patients with Spinal Disorders

Study Design: Retrospective cohort study. Purpose: The purpose of this study was to evaluate the prevalence of diffuse idiopathic skeletal hyperostosis (DISH) in patients with spinal diseases determined by roentgen images of the whole spine. Overview of Literature: Although several studies have investigated the prevalence of DISH in healthy subjects, no detailed data have been reported on the prevalence of DISH in patients with degenerative spinal disorders. Methods: Standing whole-spine roentgen images of 345 consecutive patients who underwent surgery in our hospital were obtained. Patients aged <18 years or with congenital spinal disease, metastatic spinal tumors, or inflammatory spinal disease were excluded. In total, 281 patients were eligible for inclusion. The presence of DISH was assessed according to Resnick’s criteria and Mata’s scoring system. The prevalence, location, and numbers of fused vertebral bodies of DISH were recorded. Results: DISH was present in 25.6% of patients (72/281). The prevalence of DISH in the 41–49, 50–59, 60–69, 70–79, and ≥80 year age groups was 8.3% (2/24), 9.8% (5/51), 16.0% (12/75), 49.5% (48/97), and 33.3% (4/12), respectively; the prevalence increased with age. The average number of fused vertebral bodies was 7.5. More than 80% of DISH was located from T7 to T11, and more than 95% of DISH was located at T9/10. Patients with DISH were significantly older (71.1 years vs. 60.9 years, p <0.05), and men were more likely to have DISH than women (p <0.05). Conclusions: In patients with degenerative spinal diseases with DISH, fused vertebrae were found most frequently in the lower thoracic spine, and their prevalence increased with age. DISH may be an age-related skeletal disorder with a higher overall prevalence in patients with spinal disorders than that in healthy subjects.
