Relationship Between Signal Changes on T2-weighted Magnetic Resonance Images and Cervical Dynamics in Cervical Spondylotic Myelopathy.
Technical note. ⋯ Increased segmental hyperextension curvature (≥10 degrees) and ROM are risk factors for high-intensity lesions on T2W MRI in CSM patients.

The Efficacy of Intraoperative Neurophysiological Monitoring Using Transcranial Electrically Stimulated Muscle Evoked Potentials (TcE-MsEPs) for Predicting Postoperative Segmental Upper Extremity Motor Paresis After Cervical Laminoplasty.
Prospective study. ⋯ A more than 50% wave amplitude decrease in the biceps is useful to predict acute type segmental upper extremity palsy. Further examination about the interventions for monitoring alarm will be essential for preventing palsy.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivitives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

Minimally invasive transforaminal lumbar interbody fusion (MIS TLIF) is performed via tubular dilators thereby preserving the integrity of the paraspinal musculature. The decreased soft tissue disruption in the MIS technique has been associated with significantly decreased blood loss, shorter length of hospitalization, and an expedited return to work while maintaining comparable arthrodesis rates when compared with the open technique particularly in the setting of spondylolisthesis (isthmic and degenerative), recurrent symptomatic disk herniation, spinal stenosis, pseudoarthrosis, iatrogenic instability, and spinal trauma. The purpose of this article and the accompanying video wass to demonstrate the techniques for a primary, single-level MIS TLIF.

Spondylolisthesis, Sacro-Pelvic Morphology, and Orientation in Young Gymnasts.
Cross-sectional evaluation of sacro-pelvic morphology and orientation as well as spondylolisthesis prevalence in a cohort of young gymnasts. ⋯ The prevalence of spondylolisthesis in young gymnasts was similar to that observed in the general population. Sagittal sacro-pelvic morphology and orientation was abnormal in gymnasts with spondylolisthesis. Sagittal sacro-pelvic morphology and orientation was also slightly different in gymnasts without spondylolisthesis when compared with the normal population. The present study supports an association between spondylolisthesis and abnormal sacro-pelvic orientation and morphology.

Complications and Unfavorable Clinical Outcomes in Obese and Overweight Patients Treated for Adult Lumbar or Thoracolumbar Scoliosis With Combined Anterior/Posterior Surgery.
Combined anterior/posterior (A/P) spinal fusion with instrumentation has been used for many years in the treatment of adult thoracolumbar and lumbar (TL/L) scoliosis. However, the risk factors for complications and poor clinical outcomes with this procedure are not well known. ⋯ Despite the good function scores and acceptable pain levels in most patients, the ODI scores of obese and overweight patients were worse compared to the rest of the patients in this study. Significantly worse scores on the pain intensity domain of the ODI and ASSP differences were likely caused by extensive dissection of the abdominal wall and psoas muscles and the technical difficulty of achieving an anterior approach to the thoracolumbar spine. Radiographs revealed no progression of the TL/L curves. This study indicates that obesity and overweight are potential risk factors for combined A/P-instrumented spinal fusion in patients with adult TL/L scoliosis, perhaps due to the technical difficulty of achieving an anterior approach to the thoracolumbar spine.
