Controlled Clinical Trial[Effects of wide posterior release on the correction of severe and rigid thoracic scoliosis in sagittal plane].
To explore the effects of wide posterior release on the correction of severe and rigid thoracic scoliosis in sagittal plane. ⋯ In idiopathic scoliosis patients with severe and rigid thoracic curves, wide posterior release via a posterior approach may help to correct the deformity in sagittal plan and achieve more coronal correction in these curves.

[Osteotomy for severe thoracolumbar kyphosis in advanced ankylosing spondylitis: skipping two-level pedicle subtraction osteotomy].
To explore the feasibility of single-stage skipping two-level pedicle subtraction osteotomy (PSO) for severe thoracolumbar kyphosis (Cobb > 100°) in advanced ankylosing spondylitis (AS). ⋯ As a safe and effective technique for correction of severe thoracolumbar kyphosis (Cobb > 100°) secondary to AS, single-stage skipping two-level PSO osteotomy can achieve larger correction and better sagittal alignment with a mean correction of 86°in terms of LL.

[Features of pelvic parameters in adolescent idiopathic scoliosis and their relationships with spinal sagittal parameters].
To explore the features of pelvic parameters in patients with adolescent idiopathic scoliosis (AIS) and the relationships with spinal sagittal parameters and evaluate their roles in sagittal balance. ⋯ Ethnic differences exist in the main pelvic parameters and their values are lower in Chinese than in Caucasians. There are also differences among different types of AIS. The values of main pelvic parameters are higher in AIS patients with a primary thoracic curve than in those with a primary lumbar curve. Pelvic parameters play an important role in maintaining a sagittal balance. The main pelvic parameters have influences on sagittal lumbar configuration but little on thoracic segment. A high PI value leads to a forward lean in torso with an increased PT as a result of compensation and vice versa. The alteration of PT is a major compensatory pattern of pelvis. The features of pelvic parameters should be considered during surgical planning.

[Utility of portable monitoring device with airflow, oxygen saturation and respiratory effort in the diagnosis of sleep apnea hypopnea syndrome].
To validate the values of monitoring airflow, oxygen saturation and respiratory effort in the diagnosis of sleep apnea-hypopnea syndrome (SAHS). ⋯ Portable monitoring device recording airflow, oxygen saturation and respiratory effort shows a great agreement with PSG with regards to AHI (RDI) and the identification of different types of respiratory events.
