Studies in the Falls Efficacy Scale-International for patients with cervical compressive myelopathy: Reliability, validity, and minimum clinically important difference.

Context: Patients with cervical compressive myelopathy (CCM) often complain of body balance problems, such as fear of falling and bodily unsteadiness. However, no accepted patient-reported outcome measures (PROMs) for this symptomatology exist. The Falls Efficacy Scale-International (FES-I) is one of the most widely used PROMs for evaluating impaired body balance in various clinical fields.

Decompression status of the spinal cord after cervical laminoplasty in various body positions and neck postures observed using percutaneous ultrasonography: Relationship with neurological recovery.

Background: Percutaneous ultrasonography (PUS) is used to evaluate the status of the spinal cord after cervical laminoplasty (CLP). This technique helps assess real-time movements of the spinal cord and provides immediate information regarding the decompression status. Additionally, it can also be utilized to evaluate the status of the spinal cord in various body positions and neck postures.

The Effects of Surgery on Postural Instability in Patients With Cervical Compressive Myelopathy: Evaluating Subjective Perceptions and Objective Measurements.

Study Design: A retrospective study.

Objective: To investigate the effects of surgery on the subjective perception of bodily unsteadiness and the objective measurements of postural instability in patients with cervical compressive myelopathy (CCM).

Summary Of Background Data: Several studies have demonstrated that CCM patients have impaired postural stability and investigated its surgical outcomes.

Usefulness of Percutaneous Ultrasonography for Deciding the Need of Surgical Evacuation of Epidural Hematoma After Cervical Double-door Laminoplasty.

Study Design: This was a retrospective study.

Objective: The objective of this study was to investigate the diagnostic utility of percutaneous ultrasonography (PUS) for postoperative epidural hematoma (EH) as a postoperative complication.

Summary Of Background Data: We investigated the usefulness of PUS for determining the need of surgical evacuation of postoperative EH by comparing the postoperative magnetic resonance imaging (MRI) and PUS of the spinal cord.

Preoperative Cyst Formation as a Predictive Feature of Spontaneous Regression of Retro-Odontoid Pseudotumor After Posterior Fusion.

Objective: Although the spontaneous regression of pseudotumors after posterior fusion has been reported, the predictive factors remain unclear. We examined the radiological features that predict for the regression of retro-odontoid pseudotumors after posterior fusion, with a specific focus on cyst formation.

Methods: We included 28 patients with a diagnosis of retro-odontoid pseudotumor using preoperative magnetic resonance imaging.

Significance of flexion range of motion as a risk factor for kyphotic change after cervical laminoplasty.

Kyphotic deformity is a rare but serious complication after cervical laminoplasty (CLP), and several studies have investigated its predictors. In these studies, a kyphotic Cobb angle of 0°-5° between C2 and C7 at a certain postoperative time-point was often used to detect kyphotic deformity. However, studies considering the amount of cervical lordosis loss compared to the preoperative measurement are scarce.

Surgical Outcomes of Postural Instability in Patients With Cervical Myelopathy.

Study Design: This is a retrospective study.

Objective: The objective of this study was to investigate the surgical outcomes of postural instability and its predictors in patients with cervical myelopathy (CM).

Summary Of Background Data: Although several studies have shown impaired postural stability in CM patients, there remains a paucity of literature examining its surgical outcome.

Gas containing intraspinal synovial cyst in the lumbar spine: Case report and literature review.

Intraspinal synovial cyst (ISC) is a well-documented pathology. It is sometimes found in the degenerative lumbar spine and can result in neurological disorders. ISC typically contains xanthochromic fluid, blood, inflammatory tissue, and/or osseous structures, enclosed by fibrous tissue.

Health-related quality of life, including marital and reproductive status, of middle-aged Japanese women with posterior spinal fusion using Cotrel-Dubousset instrumentation for adolescent idiopathic scoliosis: Longer than 22-year follow-up.

Background: Few studies have examined long-term outcomes after posterior spinal fusion using Cotrel-Dubousset instrumentation (CDI) for adolescent idiopathic scoliosis (AIS). Most patients with AIS are female, and their main concern is how spinal fusion will affect their future life. This study aimed to investigate the long-term health-related quality of life (HRQOL), including marital and reproductive status, of middle-aged Japanese women who underwent posterior spinal fusion using CDI for AIS in its earliest days in Japan.

Percutaneous ultrasonographic evaluation of the spinal cord after cervical laminoplasty: time-dependent changes.

Purpose: The first purpose of this study is to confirm whether the spinal cord and the surrounding tissues can be visualized clearly after laminoplasty using percutaneous ultrasonography. And second purpose is to evaluate the changes in the status of the spinal cord over time.

Methods: Fifty patients who underwent cervical laminoplasty with suture anchors were evaluated using intraoperative ultrasonography and postoperative (1 week, 2 weeks, 3 months, 6 months, and 1 year) percutaneous ultrasonography.

The Evaluation of Indirect Neural Decompression After Lateral Lumbar Interbody Fusion Using Intraoperative Computed Tomography Myelogram.

Background: The effect of indirect decompression after lateral lumbar interbody fusion (LLIF) is widely acknowledged; however, its details remain unclear. This study aimed to evaluate the immediate effects of indirect decompression just after LLIF cage placement but just before posterior instrumentation, using intraoperative computed tomography myelogram (iCTM).

Methods: Fifty-three levels from 28 patients undergoing LLIF with iCTM, were included in this retrospective study.
