BACKGROUND Severe localised ossification of the posterior longitudinal ligament (OPLL) should be directly removed by anterior approach, but the exposure during anterior cervical diskectomy and fusion (ACDF) is restricted and may increase the risk of a cerebrospinal fluid (CSF) leak. Corpectomy is facilitated to extirpate the ossification, but it is relatively more invasive. The purpose of this ...

STUDY DESIGN Descriptive, microdissection study. OBJECTIVE To determine the morphology of the human adult cervical intervertebral disc and its ligaments. SUMMARY OF BACKGROUND DATA Some studies indicate that the cervical disc is distinctly different from the lumbar intervertebral disc, yet most clinical and anatomic texts appear content with extrapolating data from the lumbar spine. A detai...

Background To determine the relationship between superior disc-endplate complex injury and correction loss after surgery in a group of young adult patients with a stable thoracolumbar burst fracture. Methods The study group was comprised of young adult patients who had undergone short-segment posterior fixation and bone grafting under the diagnosis of a stable thoracolumbar burst fracture fro...

Among the different conditions causing inflammation and calcification/ossification of the soft tissues of the spinal cord, single or recurrent traumatic events are included. Within the international literature, the involvement of the posterior longitudinal ligament, following spinal cord injuries is frequently reported, especially in the elders. The Authors describe here an uncommon calcificati...

BACKGROUND Ossification of the posterior longitudinal ligament (OPLL) of the spine is considered a multifactorial and polygenic disease. We aimed to investigate the association between four single nucleotide polymorphisms (SNPs) of pre-miRNAs [miR-146aC>G (rs2910164), miR-149T>C (rs2292832), miR-196a2T>C (rs11614913), and miR-499A>G (rs3746444)] and the risk of cervical OPLL in the Korean popul...

Ossification of the posterior longitudinal ligament (OPLL), defined as pathological hypertrophy and prominent bony formation of the posterior longitudinal ligament, compresses the spinal cord and results in myelopathy.6,12 The first report of OPLL was made in 1839.16 Tsukimoto presented the first Japanese autopsy case of cervical OPLL in 196040 and Terayama et al. gave the disease its name.38 T...

Thoracic myelopathy caused by ossifi cation of the posterior longitudinal ligament (OPLL) is rare compared to cervical OPLL, even in the Japanese population. However, once myelopathy appears in patients with thoracic OPLL, it is progressive and often leads to serious paraplegia. In such cases, surgical treatment is required because conservative treatment, such as immobilization by a brace, is n...

BACKGROUND An anterior decompression and fusion (ADF) with the floating method is an effective procedure for treating ossification of the posterior longitudinal ligament (OPLL), allowing a direct decompressive effect on the spinal cord. However, the procedure is skill-intensive, particularly in cases of OPLL with a high canal-occupying ratio. In such cases, there are potential risks for insuffi...

OBJECT The objective of this systematic review was to use evidence-based medicine to examine the efficacy of cervical laminectomy and fusion for the treatment of cervical spondylotic myelopathy (CSM). METHODS The National Library of Medicine and Cochrane Database were queried using MeSH headings and keywords relevant to cervical laminectomy, fusion, and CSM. Abstracts were reviewed, after whi...

Study Design Retrospective study. Objectives Assess demographics, ossification characteristics, surgical outcomes, and complications in patients with both diffuse idiopathic spinal hyperostosis (DISH) and ossification of the posterior longitudinal ligament (OPLL) compared with patients who only have OPLL. Methods Clinical charts and radiographs of all patients treated surgically from February 2...
