Observational Study
Patterns of sitting spinal alignment in non-ambulatory scoliosis patients with paraplegia: an observational study.
To classify sagittal spinopelvic alignment patterns of non-ambulatory scoliosis patients with paraplegia based on lateral sitting radiographs and explore their relation to clinical background and physical function. ⋯ Identified were two distinct sagittal alignment patterns in seated scoliosis patients with paraplegia, with potential influences from spasticity in the lower extremities. Recognizing these patterns can aid in assessing the function of sitting balance that includes the hip joint and in optimizing strategies for the treatment of scoliosis patients with paraplegia.

Plentiful evidence points to a significant correlation between paravertebral muscles and spinal diseases. Yet, no reports are available detailing the association between paravertebral muscle status and diffuse idiopathic skeletal hyperostosis (DISH). The purpose of this retrospective study was to assess the link between paravertebral muscle area as well as fat infiltration and DISH based on computer tomography. ⋯ In conclusion, the fat infiltration of the paravertebral muscles was significantly associated with DISH.

Clinicians monitor scoliosis progression using multiple radiographs during growth. During imaging, arms must be elevated to visualize vertebrae, possibly affecting sagittal alignment. This study aimed to determine the arm position that best represents habitual standing (and possibly allowing hand-based skeletal maturity assessment) to obtain frontal and lateral stereo-radiographs as measured using frontal, sagittal, and transverse angles. ⋯ No position represented habitual standing for all groups. When arms are raised, decreases in curve angle were shown in single-curve patients, kyphosis decreased, and lordosis increased in all groups. Most accurate positioning for all parameters was in fingers to clavicle/chin position.
