Evaluation of intraoperative coronal alignment using a computer-assisted rod bending system (CARBS) without intraoperative radiation exposure in adult spinal deformity surgery: a technical note and preliminary results.

Purpose: Intraoperative radiographs and fluoroscopy are used in adult spinal deformity (ASD) surgery to prevent postoperative coronal malalignment but with limited accuracy. Therefore, we applied a computer-assisted rod bending system (CARBS: Bendini) for an intraoperative coronal alignment evaluation. The purpose of this study is to introduce this novel technique and validate its accuracy.

Torticollis of a specific C1 dislocation with split atlas.

Study Design: A case report.

Objective: We report a novel case of torticollis disorder because of a congenital split atlas after minor trauma.

Summary Of Background Data: Torticollis experienced after minor trauma in childhood is usually because of atlantoaxial rotatory fixation, which is a common disorder in pediatric patients and is usually diagnosed with computed tomography (CT).
