Pedicle subtraction osteotomy to correct rigid deformities

Objective The aim of the surgery is to restore the sagittal profile in the event of a mismatch of the patient's spinopelvic parameters and high patient suffering. Indications Clinically symptomatic sagittal imbalance due to degeneration, trauma or after spinal surgery which can not be adequately treated by conservative therapy. Contraindications Severe general disease of the patient; local or systemic inflammation. Surgical technique A dorsal approach is used to resect the dorsal vertebral structures and to perform an osteotomy to the anterior edge of the spine. Postoperative management Rest with a load limit of 5kg for 3 months. Prohibition of deep sitting for this time. Results The pedicle subtraction osteotomy is described in the literature as a reliable method for the treatment of sagittal imbalance. The high rate of described complications should be discussed preoperatively with the patient.
