Effect of asymptomatic postoperative epidural hematoma on recovery rate after surgery for myelopathy caused by thoracic ossified ligamentum flavum.

Aim: To analyze the clinical characteristics of thoracic ossified ligamentum flavum (OLF) and clarify prognostic factors.

Material And Methods: We retrospectively collected clinical data from the medical records of 29 patients who underwent decompressive surgery for myelopathy caused by thoracic OLF from 2011 to 2019. Associations between various clinical and radiological factors and surgical outcomes were analyzed.

C6 nerve root palsy after double-door cervical laminoplasty.

Background: This study correlated the relationship between postoperative C6 nerve root palsies and various patient-related clinical, radiographic, and surgical parameters.

Prevalence and Screening of Deep Vein Thrombosis in Patients with Osteoporotic Vertebral Fracture.

Aim: To determine the prevalence of a deep vein thrombosis (DVT) in osteoporotic vertebral fractures.

Material And Methods: Data were retrospectively collected from the medical records of 50 patients who were admitted to the Kameda Medical Center for osteoporotic vertebral fracture from 2019 to 2020. Inpatients were screened for DVT using D-dimer, and those who were screened positive underwent lower extremity venous ultrasonography to confirm DVT.

Two cases of normal pressure hydrocephalus caused by ependymoma of the cauda equina.

Background: Normal pressure hydrocephalus (NPH) associated with tumors of the cauda equina is rare. Here, we report two cases of NPH attributed to cauda equina ependymomas.

Case Description: A 63-year-old male presented with progressive gait disturbance, dementia, and urinary incontinence.

Tumoral Calcinosis of Thoracic Spine Associated with Vertebral Fracture and Inflammatory Reactions.

Tumoral calcinosis involving the spine is rare. The involvement of the thoracic spine is rarer than that of the cervical or lumbar spine. We report a case of thoracic tumoral calcinosis accompanied by vertebral fracture with increased concentrations of inflammatory markers and no abnormalities in serum calcinosis and phosphorus concentration.
