Early Experience and Initial Outcomes With Patient-Specific Spine Rods for Adult Spinal Deformity

The objectives of this study were to describe the process of preoperative planning and using patient-specific rods. This retrospective case series involved 18 patients with adult spinal deformity who were treated with posterior instrumentation and spine fusion, with lumbar or thoracic osteotomies, using patient-specific rods. Data extracted included demographic/surgical variables and preoperative, predicted (surgical plan), and postoperative spinopelvic parameters. The outcome analysis involved assessment of preoperative, planned, and postoperative variables. Treatment effect evaluation involved assessing differences between preoperative and postoperative values and correspondence between planned and achieved results. Surgery using preoperative planned patient-specific rods led to excellent adult spinal deformity correction and spinopelvic alignment.
