Study Design: Prospective single-center study.
Purpose: To compare the accuracy of pedicle screws placed by freehand and under fluoroscopy and robotic assistance with intraoperative image acquisition.
Overview Of Literature: Pedicle screws are the most commonly used spinal anchors owing to their ability to stabilize all three spinal columns.
Aims And Objectives: To determine accuracy of pedicle screws placed by freehand, fluoroscopy-assistance and robotic-assistance with intraoperative image acquisition, and determine the presence of learning curve in robotic spine surgery in a prospective single centre study.
Materials And Methods: In a prospective study, a total of 1120 pedicle screws were placed in Freehand group (n = 175), 1250 screws were placed in fluoroscopy-assisted group (n = 172), and 1225 screws were inserted in Robotic-assisted group(n = 180). Surgical parameters and screw accuracy were analyzed between the three groups.
Study Design: Retrospective radiographic study.
Objective: To assess whether flexibility as revealed by the supine radiograph, predicts in-brace curve correction.
Summary Of Background Data: Currently there is no consensus regarding a standard method to assess curve flexibility and immediate brace effectiveness in treating adolescent idiopathic scoliosis (AIS).
Study Design: Prospective clinical-radiographic study.
Objectives: To investigate the natural coupling behavior between frontal deformity correction and the simultaneous changes in thoracic kyphosis, and to examine how the postoperative thoracic sagittal realignment relates to this natural coupling behavior.
Summary Of Background Data: Restoration of the sagittal alignment is one of the fundamental goals in scoliosis correction surgery.
