Lumbar Spondylolysis After Posterior Corrective Fusion for Adolescent Idiopathic Scoliosis: A Report of Two Cases and Literature Review.

After corrective surgery for adolescent idiopathic scoliosis (AIS), patients can return to sports activities without restrictions. While there have been many reports of long-term disc degeneration between adjacent segments after posterior corrective fusion, the effects of sports activities on adjacent segments after corrective fusion surgery are not well understood. Particularly, cases of acquired spondylolysis after long fusion surgeries for scoliosis are rare.

Association Between Kyphosis and Sleep Disturbance in Community-Dwelling Older Adults: The Locomotive Syndrome and Health Outcome in Aizu Cohort Study.

Purpose: Worsening sagittal alignment of the spine, particularly kyphosis, may cause difficulty in assuming a supine position, restricting sleeping posture and movement and potentially leading to sleep disturbances. However, no studies have explored the relationship between sagittal spinal alignment and sleep disturbance. This study aimed to clarify the relationship between sagittal spinal alignment and sleep disturbance.

Surgical Outcomes of Posterior Arch Resection of the Atlas Alone for Upper Cervical Myelopathy in Patients With Athetoid Cerebral Palsy: A Report of Two Cases.

This study reports two cases of upper cervical myelopathy with athetoid cerebral palsy (ACP) treated with posterior arch resection. Both patients exhibited good long-term outcomes with no recurrence at five or 10 years. Decompression surgery can be effective for ACP patients with upper cervical spine lesions.

Successful treatment with olanzapine and aripiprazole of a schizophrenic patient who developed priapism after switching from risperidone to paliperidone.

Background: Ischemic priapism is a rare pathological condition, and delayed intervention can result in irreversible sequelae. Most cases are attributed to the use of antipsychotics. The blockade of α1-adrenergic receptors is thought to be associated with the disease onset, although data supporting this hypothesis are lacking.

Effects of Palliative Surgical Treatment for Spinal Metastases on the Patient's Quality of Life With a Focus on the Segment of the Metastasis: A Prospective Multicenter Study.

Study Design: Prospective multicenter study.

Objectives: Palliative surgery is crucial for maintaining the quality of life (QOL) in patients with spinal metastases. This study aimed to compare the short-term outcomes of QOL after palliative surgery between patients with metastatic spinal tumors at different segments.

Radiographic Knee Osteoarthritis Is a Risk Factor for the Development of Dementia: Locomotive Syndrome and Health Outcomes in the Aizu Cohort Study.

Objective: Osteoarthritis is linked to dementia, but no longitudinal studies have established this connection. This prospective cohort study from the Locomotive Syndrome and Health Outcome in Aizu Cohort Study (LOHAS) aimed to determine if knee osteoarthritis (KOA) independently predicts dementia in adults aged 65 and above.

Methods: Participants were classified by the Kellgren-Laurence scale into no/minimal KOA (grades 0 and I) and definitive KOA (grade II or higher).

A Professional Basketball Player Who Suffered an Open Ankle Dislocation Without an Associated Fracture Achieves His Prior Performance Level Three Months Later.

An ankle dislocation without an accompanying fracture is extremely rare, and an open ankle dislocation is even rarer. Due to its rarity, there is no consensus on the optimal treatment strategy. A professional basketball player (a 28-year-old male) incurred an open ankle dislocation (with no accompanying fracture) during a basketball game due to plantar flexion and inversion of his ankle during the transition from dashing to stop motion.

Foot Tapping Test as a Simple Quantitative Index of Motor Function for Lumbosacral Radiculopathy.

Study Design: We conducted a retrospective review of data from patients who underwent surgical treatment for lumbosacral radiculopathy.

Objective: To assess the effectiveness of the foot tapping test (FTT) in evaluating lower limb motor function in patients with lumbosacral radiculopathy pre and postsurgery.

Background: Lumbosacral radiculopathy is becoming increasingly common in aging populations.

Spinal subdural hematoma with sudden onset of paraplegia in a patient on oral anticoagulant therapy.

Spinal subdural hematoma is uncommon but may become more prevalent with increasing anticoagulant use. Early diagnosis from symptoms like lower back pain and leg paralysis is crucial for timely intervention.

A new era in the management of spinal metastasis.

Despite the recent advances in cancer treatment, the incidence of patients with spinal metastases continues to grow along with the total number of cancer patients. Spinal metastases can significantly impair activities of daily living (ADL) and quality of life (QOL), compared with other types of bone metastases, as they are characterized with severe pain and paralysis caused by skeletal-related events. Reduced ADL can also lead to treatment limitations as certain anticancer agents and radiation therapy are not compatible treatments; thus, leading to a shorter life expectancy.

Time Course of Asymptomatic Stenosis in Multiple Lumbar Spinal Stenosis-Five-Year Results of Selective Decompression of Symptomatic Levels.

: In the diagnosis of lumbar spinal stenosis (LSS), finding stenosis with magnetic resonance imaging (MRI) does not always correlate with symptoms such as sciatica or intermittent claudication. We perform decompression surgery only for cases where the levels diagnosed from neurological findings are symptomatic, even if multiple stenoses are observed on MRI. The objective of this study was to examine the time course of asymptomatic stenosis in patients with LSS after they underwent decompression surgery for symptomatic stenosis.

The Usefulness of Deep Tendon Reflexes in the Diagnosis of Lumbar Spine Diseases: A Narrative Review.

The deep tendon reflex (DTR) is a more objective indicator than sensory and muscle assessments for lumbar spine disorders. Further, unlike sensory and muscle assessments that require patient cooperation, the DTR can be assessed even in patients with impaired consciousness or cognition. Therefore, DTR assessment with a hammer is an essential neurological test for lumbar spinal diseases.

A reduction method for anterior opening displacement in thoracolumbarvertebral fractures with diffuse idiopathic skeletal hyperostosis using the skull clamp-assisted position.

Diffuse idiopathic skeletal hyperostosis (DISH) frequently occurs in the spine, resulting in unstable fractures. Treating thoracolumbar fractures in patients with DISH is often difficult because the anterior opening of the vertebral body is exacerbated by dislocation in the prone position, making reduction difficult. In this study, we introduced a novel skull clamp-assisted positioning (SAP) technique.

Reference values of lumbar spine range of motion by sex and age based on the assessment of supine trunk lateral bending-A preliminary study.

[Purpose] The purpose of this study was to clarify the preliminary reference values for the lumbar spine range of motion associated with lateral bending exercises by gender and age group. [Methods] Subjects were 82 volunteers without low back pain, including five males and five females in each age group from 16-19 to 80-89 years. All subjects underwent radiographs of the lumbar spine with lateral flexion; the range of lateral flexion of the vertebrae from T12 to the sacrum (ROLB) was measured twice by three observers.

Assessment of Lumbar Spinal Stenosis as a Risk Factor for Development of Sleep Disorder: The Locomotive Syndrome and Health Outcome in Aizu Cohort Study (LOHAS).

Purpose: Insomnia has been reported to coexist with various musculoskeletal disorders. Although lumbar spinal stenosis (LSS) is the most frequently operated on spinal disease, the causal relationship between LSS and development of sleep disorders remains unclear due to lack of longitudinal studies. This study aimed to determine whether LSS was a risk factor for developing new sleep disorders, primarily insomnia, using a prospective cohort of community residents.

Blood data trends of children in Fukushima after the Great East Japan Earthquake: Fukushima health management survey.

Background: After the Great East Japan Earthquake on March 11, 2011 and the subsequent accident at the Tokyo Electric Power Company-operated Daiichi Nuclear Power Plant, the Fukushima Prefecture government initiated the Fukushima Health Management Survey (FHMS) to assess the long-term health effects of the disaster on Fukushima residents. The blood tests of children aged ≤15 years between 2011 and 2012 did not reveal any changes regarding peripheral blood data; however, long-term monitoring is still necessary. Therefore, this study aimed to investigate the long-term health status of children aged ≤15 years who had evacuated the Fukushima Prefecture.

A muscle-preserving, spinous process-splitting approach for ossification of the ligamentum flavum in the thoracic spine in professional athletes: a report of three cases.

A muscle-preserving, spinous process-splitting approach may be a less invasive approach to conventional laminectomy in patients with thoracic ossification of the ligamentum flavum. Few reports have discussed the usefulness of this procedure for thoracic lesions in professional athletes who need highly active thoracic spinal function after surgery. The treatment of thoracic ossification of the ligamentum flavum using a spinous process-splitting approach in 3 professional athletes is presented.

Development of a Novel Diagnostic Support Tool for Degenerative Cervical Myelopathy Combining 10-s Grip and Release Test and Grip Strength: A Pilot Study.

Early diagnosis of degenerative cervical myelopathy (DCM) is desirable, as delayed treatment can cause irreversible spinal cord injury and subsequent activity of daily living (ADL) impairment. We attempted to develop a straightforward and accurate diagnostic tool for DCM by combining the grip and release test (GRT) and grip strength. As a pilot study, we measured the GRT and grip strength of patients with DCM (n = 247) and a control group (n = 721).

Lumbar spinal stenosis is a risk factor for the development of dementia: locomotive syndrome and health outcomes in the Aizu cohort study.

Purpose: It remains unclear whether musculoskeletal diseases are risk factors for dementia development. This prospective cohort study of community-dwelling residents aimed to clarify the impact of lumbar spinal stenosis (LSS) on dementia development.

Methods: We included participants aged ≥ 65 years from the Locomotive Syndrome and Health Outcomes in the Aizu cohort study.

Lateral- or prone-position video-assisted thoracic surgery for dumbbell-type posterior mediastinal tumors: pros and cons.

Unlabelled: Surgery for dumbbell-type posterior mediastinal tumors (D-PMTs) is difficult because surgeons should confirm the tumor's extension into the spinal cord and pay attention to the Adamkiewicz artery. We describe two patients of D-PMTs who underwent lateral- or prone-position video-assisted thoracic surgery (VATS). In patient 1 (a 70-year-old woman), the tumor extended to the spinal canal through the fourth thoracic intervertebral foramen.

Generalization of a clinical diagnosis support tool for lumbar spinal stenosis: Can the ankle brachial pressure index be replaced by palpation of the posterior tibial artery in the lumbar spinal stenosis diagnostic support tool? (DISTO project).

Background: The Japanese Society for Spine Surgery and Related Research previously developed a diagnostic support tool for lumbar spinal stenosis (LSS-DST). Using the LSS-DST, general physicians can identify potential cases of LSS. However, in the LSS-DST, measurement of the ankle brachial pressure index (ABI) is required to exclude peripheral artery lesions in the lower limbs.

Grip Strength as a Screening Index for Severe Degenerative Cervical Myelopathy in Primary Care: Development of Cutoff Values Using Receiver Operating Curve Analysis.

Purpose: Early diagnosis of degenerative cervical spondylosis (DCM) is desirable because late treatment can lead to irreversible sequelae. No screening method has yet been established. Grip strength is commonly used in primary care settings to evaluate disease activity and diagnose sarcopenia.
