To investigate the impact of preoperative compensatory curve on the postoperative curve progression in congenital scoliosis (CS) patients following thoracolumbar hemivertebra (HV) resection and short fusion. ⋯ The presence of the compensatory curve was associated with a higher incidence of postoperative curve progression in patients with CS who underwent thoracolumbar HV resection and short fusion. Shorter fusion segments and greater postoperative UIV tilt were found to be the risk factors for postoperative curve progression.

There is a paucity of data regarding the sagittal spine-pelvis-leg alignment and the compensatory mechanisms in patients with lumbar spinal stenosis (LSS) and hip osteoarthritis (HOA). In this study, we aim to evaluate the association of HOA with sagittal spine-pelvis alignment parameters in a population of patients with lumbar spinal stenosis and sagittal malalignment. ⋯ In this PSM study, patients with SOA exhibit reduced pelvic tilt and hip extension in standing positions compared to those with LOA. Additionally, the SOA patients had worse global sagittal alignment than their LOA counterparts.

Paraspinal and spinopelvic muscular dysfunction are hypothesized to be a causative factor for spinal degeneration and deformity; however, our fundamental understanding of paraspinal muscle (dys)function remains limited. ⋯ This study is the first to show a heightened intrinsic contractile muscle disorder (i.e. impaired specific force generation) in patients with spinal degeneration who are sagittally imbalanced (compared to patients without deformity). Additionally, there are clear indications that patients with spinal degeneration (all groups) have intrinsic force sarcomere-length properties that are dysregulated. This provides important insight into the pathophysiology of muscle weakness in this patient group.

This study aimed to distinguish tuberculous spondylodiscitis (TS) from pyogenic spondylodiscitis (PS) based on laboratory, magnetic resonance imaging (MRI) and computed tomography (CT) findings. Further, a novel diagnostic model for differential diagnosis was developed. ⋯ This study develop a good diagnostic model based on both CT and MRI, as well as laboratory findings, which may help clinicians distinguish between TS and PS.

Since scoliosis is a three-dimensional deformity, it causes some movement limitations in the spine and related joints. However, functional limitations associated with scoliosis-related hip joint involvement are the subject of research. ⋯ Individuals with IS show decreased hip mobility, lumbopelvic stability, hip joint position sense, and balance compared to healthy peers; however, these limitations do not have a clinical impact on daily living activities.
