To evaluate outcomes of choosing different Roussouly shapes and improving in Schwab modifiers for surgical Roussouly type 1 patients. ⋯ For ASD patients classified as Roussouly type 1, postoperative improvement in SRS-Schwab grades reflected superior patient-reported outcomes while type 1 and type 2 did not differ in clinical outcomes at 2Y. However, development of type 3a should be avoided at the risk of poor functional outcomes. Utilizing both classification systems in surgical decision-making can optimize postoperative outcomes.

Pain-related single nucleotide polymorphisms: association with lumbar spinal stenosis patient experience and non-surgical treatment outcomes.
Lumbar spinal stenosis (LSS) is common in our aging population resulting in pain and functional impairment. Recent advances in pain research have identified several single nucleotide polymorphisms (SNP) associated with inter-individual symptom and treatment response. The goal of the current study was to investigate the association of SNPs in Neuropeptide Y (NPY) and Catechol-O-methyltransferase (COMT) with pain, function, and treatment outcomes in Lumbar spinal stenosis (LSS) patients receiving non-surgical treatments. ⋯ NPY rs16147 and COMT rs4680 are important potential biomarkers associated with pain and function. NPY genotype may be useful in predicting response to non-surgical treatments in older adults with LSS.

We investigated the recovery of the Japanese orthopedic association back pain evaluation questionnaire (JOABPEQ) scores and 6 min walk distance (6MWD) in patients after surgery for lumbar spinal stenosis and identified the items among 25 questions of JOABPEQ that showed recovery. ⋯ Our results demonstrated the early postoperative recovery course of JOABPEQ and 6MWD. In the fusion group, significant changes in lumbar spine dysfunction started at 6 months postoperatively. These findings could help medical staff explain postoperative recovery to patients after lumbar spinal stenosis surgery and in their decision making regarding surgery.

This study identifies risk factors for neurophysiological events caused by intraoperative halo-femoral traction (IOHFT) in patients with adolescent idiopathic scoliosis (AIS), and neuromuscular scoliosis (NMS). ⋯ Neurophysiologic events due to IOHFT were common, with the majority in patients with NMS. A shorter stature was a risk factor, and larger Cobb angle and stiffer curve were associated with IOHFT-events. Events occurred at any stage of surgery and involved upper and lower limbs. With an adequate response on IOHFT events, none of the patients had postoperative neurological impairments due to IOHFT.

The role of thoracolumbar fascia (TLF) in the development of chronic low back pain (CLBP) has growing evidence in the literature. Although CLBP is reported in individuals with idiopathic scoliosis (IS), its relationship with the TLF has yet not been established. This study aims to evaluate the TLF and its relationship with CLBP in IS. ⋯ Thickening of the TLF was observed in IS, whereby, in the presence of CLBP, it was further intensified. We suggest considering fascial thickening as a potential contributing factor to both pain and limited motion in relevant patients.
