Article Synopsis
- The study is a retrospective clinical analysis focusing on the role of the patellar tendon reflex (PTR), bulbocavernosus reflex (BCR), and plantar response (PR) in predicting motor function recovery in patients with complete paralysis from cervical spinal cord injuries (CSCIs).
- Conducted at a spinal injuries center in Japan, it involved 99 patients categorized as AIS grade A and evaluated their reflex responses at the time of injury, classifying them into "recovered" or "non-recovered" groups based on their status three months later.
- The findings indicated that PTR and PR are significantly associated with recovery outcomes, showing that positive responses correlate with better prognoses, whereas the BCR did not demonstrate a significant predictive value
Study Design: A retrospective review of a case series of five participants.
Objective: To elucidate the effects of post-cervical laminoplasty on the clinical pathophysiology of traumatic CSCI. Cervical laminoplasty has been widely performed with good results in individuals for cervical myelopathy.
Article Synopsis
- The study investigates the occurrence and risk factors for pneumonia in individuals who suffered from acute traumatic cervical spinal cord injury (CSCI) in a spinal injuries center in Japan.
- Out of 167 patients analyzed, 30 (or 18%) developed pneumonia, with the majority (87%) linked to aspiration due to swallowing difficulties.
- Key risk factors identified include severity of spinal injury and dysphagia, establishing the importance of addressing swallowing issues early to help prevent pneumonia.
To investigate the usefulness of the combination of neurological findings and magnetic resonance imaging (MRI) as a prognostic predictor in patients with motor complete cervical spinal cord injury (CSCI) in the acute phase. A cross-sectional analysis Department of Orthopaedic Surgery, Spinal Injuries Center Forty-two patients with an initial diagnosis of motor complete CSCI (AIS A, = 29; AIS B, = 13) within 72 h after injury were classified into the recovery group (Group R) and the non-recovery group (Group N), based on the presence or absence of motor recovery (conversion from AIS A/B to C/D) at three months after injury, respectively. The Neurological Level of Injury (NLI) at the initial diagnosis was investigated and the presumptive primary injured segment of the spinal cord was inferred from MRI performed at the initial diagnosis.

- A case report details an 86-year-old woman who experienced a rare acute attack of calcium pyrophosphate dihydrate (CPPD) deposition disease, specifically pseudogout, manifesting as neurological deficits linked to lumbar spondylolytic spondylolisthesis.
- Diagnostic imaging revealed extensive lesions and effusions in her lumbar region, prompting initial misdiagnosis of pyogenic arthritis before further tests confirmed the presence of crystal deposits.
- Treatment with nonsteroidal anti-inflammatory drugs (NSAIDs) led to significant improvement in both her inflammatory and neurological symptoms.
Rationale: Spontaneous spinal subdural hematoma (SSDH) is a rare disease that can cause severe permanent neurological dysfunction. Here we present a case of spontaneous SSDH, in which a series of magnetic resonance images (MRIs) taken through the course of the disease facilitated understanding of the resolution process of the hematoma and the diagnosis of SSDH.
Patient Concerns: A 59-year-old male presented with sudden severe back pain and rapid onset of paraplegia.
Study Design: Retrospective chart audits.
Objective: To investigate the optimal timing at which permanent complete cervical spinal cord injury (CSCI) can be confirmed when evaluating paralysis caused by traumatic CSCI.
Setting: Department of Orthopedic Surgery, Spinal Injuries Center, Japan.
Background: Augmented renal clearance (ARC) of circulating solutes and drugs has been recently often reported in intensive care unit (ICU) patients. However, only few studies on ARC have been reported in Japan. The aims of this pilot study were to determine the prevalence and risk factors for ARC in Japanese ICU patients with normal serum creatinine levels and to evaluate the association between ARC and estimated glomerular filtration rate (eGFR) calculated using the Japanese equation.
