INTRODUCTION: Proximal junctional kyphosis (PJK) of the cervicothoracic spine is a deformity that can affect patients who have undergone long thoracolumbar instrumented fusion. Preoperative hyperkyphosis of the thoracic spine and changes of more than 30° in lumbar lordosis are independent risk factors for the onset of PJK. METHODS: When PJK occurs in the cervicothoracic spine, extension of the fusion with eventual application of osteotomy techniques is frequently necessary to treat symptomatic patients or in case a neurological deficit occurs...

INTRODUCTION: When a deformity involves more than one area of the spine, it becomes a multifocal deformity; such a deformity could either be extending on two adjacent segments, or be two separated deformities on two non-adjacent segments. MATERIALS AND METHODS: The surgical management of multifocal spinal deformities is challenging and must be done through a thorough preoperative planning where spinal and pelvic parameters should accurately be determined. Different strategies should be applied depending on the type of the multifocal deformity, the area involved, the angulation and stiffness of the spine in that area, and the presence of either a pure sagittal malalignment or a combined coronal and sagittal malalignment...

BACKGROUND: Supine imaging modalities provide valuable 3D information on scoliotic anatomy, but the altered spine geometry between the supine and standing positions affects the Cobb angle measurement. Previous studies report a mean 7°-10° Cobb angle increase from supine to standing, but none have reported the effect of endplate pre-selection or whether other parameters affect this Cobb angle difference. METHODS: Cobb angles from existing coronal radiographs were compared to those on existing low-dose CT scans taken within three months of the reference radiograph for a group of females with adolescent idiopathic scoliosis...

PURPOSE: To analyze risk factors for an increase in proximal junctional angle (PJA) after posterior selective thoracolumbar/lumbar (TL/L) curve fusion in patients with adolescent idiopathic scoliosis (AIS). METHODS: AIS patients that underwent selective posterior TL/L curve fusion with a minimum of 2-year follow-up were identified. Demographic and radiographic data were collected before surgery, at first erect after surgery and at final follow-up. Multiple linear regression analysis was performed to determine the relation of PJA changes during follow-up and eight potential risk factors, including locations of upper instrumented vertebra (UIV), locations of lower instrumented vertebra (LIV), length of fusion segments, types of pedicle screw alignment, lumbar lordosis (LL) at first erect after surgery, LL changes before and after surgery, sagittal vertical axis (SVA) at first erect after surgery and SVA changes before and after surgery...

BACKGROUND CONTEXT: Single pedicle subtraction osteotomy (PSO) has been used to correct ankylosing spondylitis (AS) kyphosis successfully, but this approach seems insufficient to correct severe kyphosis. Two-level PSO has been attempted to correct advanced kyphosis in recent years. However, studies have not yet compared outcomes between single and double PSOs, and the indications to perform two-level PSO are unclear. PURPOSE: This study aimed to compare the radiologic and clinical outcomes between single- and two-level PSOs in correcting AS kyphosis...
