This study compared the vertical spinal creep response between adolescent and adult males. Thirty healthy male subjects, 15 adolescents (aged 12 to 16 years) and 15 adults (aged 30 to 57 years) were measured. Spinal creep was measured continuously over 25 min under loaded and unloaded conditions using a seated stadiometer that controlled spinal posture. Both adolescent and adult subjects showed significant increase in vertical spinal creep with time but the magnitude of vertical spinal creep was significantly greater in adolescent than in the adult subjects.

Characteristics of Sciatic Scoliosis in Lumbar Disc Herniation and Comparative Radiographic Outcomes After Treatment With Full-Endoscopic Interlaminar Discectomy.

Study Design: Retrospective cohort study.
Background: Sciatic scoliosis is attributed to non-structural scoliosis resulting from the irritation of spinal nerve roots. Although limited research has addressed the specific characteristics of sciatic scoliotic curve patterns, there is a lack of reported data on the pre- and post-radiographic outcomes of patients with sciatic scoliosis caused by lumbar disc herniation who have undergone full-endoscopic interlaminar discectomy (FEID).

Background And Objectives: Accurate intraoperative assessment of coronal alignment is critical to achieving favorable clinical outcomes in adult spinal deformity surgery. However, surgical positioning creates challenges in predicting standing coronal alignment. Gravity-based plumblines require an upright posture and are not possible intraoperatively.

Background: Minimizing radiation exposure is crucial in monitoring adolescent idiopathic scoliosis (AIS). Generative adversarial networks (GANs) have emerged as valuable tools being able to generate high-quality synthetic images. This study explores the use of GANs to generate synthetic sagittal radiographs from coronal views in AIS patients.

Musculoskeletal modeling based on inverse dynamics provides a cost-effective non-invasive means for calculating intersegmental joint reaction forces and moments, solely relying on kinematic data, easily obtained from smart wearables. On the other hand, the accuracy and precision of such models strongly hinge upon the selected scaling methodology tailored to subject-specific data. This study investigates the impact of upper body mass distribution on internal and external kinetics computed using a comprehensive musculoskeletal model during level walking in both normal weight and obese individuals.

Background: One-hole split endoscopy (OSE) is a novel endoscopic technique that offers some advantages in spinal surgery. However, without a clear understanding of the safe zone for OSE, surgeons risk injuring nerve roots during the procedure. This study aimed to measure the safe distances among critical bone markers, the intervertebral space and nerve roots between 1-degree degenerative lumbar spondylolisthesis (DLS) and non-DLS at the L segment in patients via three-dimensional reconstruction and to compare the differences in relevant safety distances between the two groups.
