Comparative Study Clinical TrialComparative study of kyphoplasty for chronic painful osteoporotic vertebral compression fractures via unipedicular versus bipedicular approach.
A comparative study of chronic painful osteoporotic vertebral compression fractures (OVCFs), which underwent kyphoplasty via unipedicular versus bipedicular approach. ⋯ Chronic painful OVCFs should be candidates for KP, and there was no difference in pain relief when treated with either unipedicular or bipedicular KP.Although the bipedicular KP is more efficacious in vertebral height restoration in early stage, the unipedicular KP can maintain the same degree of the restored vertebral height in the long run.

Using side-bending radiographs to determine the distal fusion level in patients with single thoracic idiopathic scoliosis undergoing posterior correction with pedicle screws.
Prospective. ⋯ The method described was effective in obtaining satisfactory curve correction, adequate trunk balance, and preservation of motion segments.

Case ReportsCyclic sciatica in a patient with deep monolateral endometriosis infiltrating the right sciatic nerve.
Case report. ⋯ Endometriosis is a chronic inflammatory disease, potentially infiltrating the somatic nerves. Laparoscopic neurolysis is a therapeutic aetiological therapy, which can relieve neurological symptoms deriving from nerve infiltration/compression.

Digital 3-dimensional analysis of the paravertebral lumbar muscles after circumferential single-level fusion.
A retrospective controlled cohort study was performed for postoperative 3-dimensional muscle evaluation. ⋯ We established a 3-dimensional image analysis method for evaluating postoperative changes in the lumbar paravertebral muscles of patients, after circumferential single-level fusion, consistently accounting for implant-associated artifacts. We were able to demonstrate volume atrophy and an increase of fatty degeneration after 12 months compared with 1 week postoperatively.

Changes of upper thoracic curve and shoulder balance in thoracic adolescent idiopathic scoliosis treated by anterior selective thoracic fusion using VATS.
A retrospective radiographic analysis. ⋯ Among patients who have DT curve, patients with mild left shoulder elevation (<20 mm) can be treated by anterior correction unless the magnitude of upper thoracic curve or superior portion of lower thoracic curve are ≥30 degrees. For anterior correction, criteria of DT curve might be applied less strictly.
