Open AccessSuccessful surgical intervention for acute pyothorax caused by methicillin-resistant Staphylococcus aureus thoracic pyogenic spondylitis: a case report
Pyogenic spondylitis or intervertebral discitis rarely spreads into the thoracic cavity, resulting in pyothorax. Moreover, no study has reported methicillin-resistant Staphylococcus aureus (MRSA) as a cause. Cons...

Chapter
Thoracic Disk Herniation
Thoracic disk herniation (TDH) can cause spinal cord compression due to the prolapse of the thoracic disk into the spinal canal; it is associated with numbness and symptoms of thoracic myelopathy (weakness of ...

Open AccessThe impact of ossification spread on cervical spine function in patients with ossification of the posterior longitudinal ligament
Ossification of the posterior longitudinal ligament (OPLL) is a progressive disease. The bridging of ossified lesions to the vertebral body gradually increases, thereby decreasing the mobility of the cervical ...

Article
Open AccessNeurological improvement is associated with neck pain attenuation after surgery for cervical ossification of the posterior longitudinal ligament
Although favourable surgical outcomes for myelopathy caused by cervical ossification of the posterior longitudinal ligament (OPLL) have been reported, factors significantly associated with post-operative neck ...

Article
Open AccessClinical characteristics in patients with ossification of the posterior longitudinal ligament: A prospective multi-institutional cross-sectional study
Ossification of the posterior longitudinal ligament (OPLL) can occur throughout the entire spine and can sometimes lead to spinal disorder. Although patients with OPLL sometimes develop physical limitations be...

Article
Open AccessSacroiliac joint variation associated with diffuse idiopathic skeletal hyperostosis
Diffuse idiopathic skeletal hyperostosis (DISH) is characterized by the ossification of vertebral bodies and peripheral entheses. However, variations in sacroiliac (SI) joint change in patients with DISH have ...

Chapter
Open-Door Laminoplasty for Cervical OPLL: Technique, Long-Term Results, and Complications
Cervical laminoplasty has become a standard procedure for the posterior decompression of the cervical cord, as ossification of the posterior longitudinal ligament (OPLL) a potential of cervical cord compressio...
