Pedicle subtraction osteotomy to correct rigid deformities

Abstract

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 5 kg 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.
