Background: Robotic platforms have increased in sophistication for pedicle screw placement. Here, we review our institutional experience using ExcelsiusGPS to assess the accuracy rate of pedicle screw placement throughout the spine and characterize predictors of placement inaccuracy.
Study Design: Retrospective cohort study.
Purpose: This study sought to compare screw placement accuracy and outcomes between freehand (FH) and AR-guided pelvic fixation. While pelvic fixation is a critical technique in spinal deformity surgery, S2-alar iliac (S2AI) screw placement poses challenges.
Methods: We conducted a case-control study of 50 consecutive patients who underwent spinopelvic fixation at a single institution.
Article Synopsis
- The study focused on posterior vertebral column subtraction osteotomy (PVCSO), a surgical procedure aimed at alleviating symptoms in patients with recurrent tethered cord syndrome (TCS) by shortening the spinal column and relieving tension on the spinal cord.
- Researchers retrospectively analyzed six patients who underwent PVCSO from 2019 to 2023, measuring changes in spinal cord dimensions through MRI and recording clinical outcomes such as motor function and pain relief after surgery.
- Results showed significant improvements in motor function for all patients, sensory function for 40%, and pain relief for 83%, along with notable anatomical changes in the spinal cord, indicating successful outcomes and minimal complications associated with the surgery.
Article Synopsis
- - The study investigates outcomes of prenatal versus postnatal surgical repair of myelomeningocele (MMC), a severe form of spina bifida, focusing on factors like spinal cord tethering and other complications.
- - A total of 18 patients were reviewed from 2002 to 2020, with equal groups for prenatal and postnatal repair, and demographic data collected included age, sex, and medical history.
- - Results showed that patients who had prenatal closure experienced fewer detethering procedures and lower rates of requiring a ventriculoperitoneal shunt compared to those with postnatal repair, highlighting potential benefits of prenatal surgery.
Objective: Pedicle screw placement guidance is critical in spinal fusions, and spinal surgery robots aim to improve accuracy and reduce complications. Current literature has yet to compare the relative merits of available robotic systems. In this review, the authors aimed to 1) assess the current state of spinal robotics literature; 2) conduct a meta-analysis of robotic performance based on accuracy, speed, and safety; and 3) offer recommendations for robotic system selection.
