Surgically assisted rapid palatal expansion (SARPE) is associated with postoperative cephalometric changes. In this study we analyse these changes in the sagittal plane in orthognathic patients undergoing SARPE followed by orthodontic treatment and Le Fort I, bilateral sagittal split osteotomy (BSSO), or bimaxillary surgery. This is a retrospective review of 50 patients (20 males, 30 females) u...

STUDY DESIGN: A description of pedicle subtraction osteotomy for correction of kyphotic deformity of the cervical-thoracic spine and a prospective evaluation of the surgical outcomes. OBJECTIVES: To describe the surgical technique and the postoperative results of pedicle subtraction osteotomy in the upper thoracic spine and the cervical-thoracic junction. SUMMARY OF BACKGROUND DATA: Pedicle sub...

For opening wedge high tibial osteotomy (OWHTO), it is recommended that the osteotomy line is parallel to the medial tibial posterior slope (TPS) in the sagittal view and that the alignments are simultaneously controlled in the coronal and sagittal views. Here combined computed tomography (CT)-based and image-free navigation systems were used for intraoperative reference during OWHTO. Using the...
