Article Synopsis
  • Surgical management of adolescent idiopathic scoliosis (AIS) and Scheuermann's kyphosis (SK) can lead to complications like longer hospital stays and unplanned surgeries, but there hasn't been a comprehensive meta-analysis on this topic.
  • The meta-analysis reviewed seven studies involving 4,866 patients and found that SK patients had significantly higher rates of complications, surgical-site infections, readmissions, and reoperations compared to AIS patients, even though their SRS-22 satisfaction scores were similar post-surgery.
  • The findings suggest that while SK patients experience more complications from surgery, the surgical treatment still provides similar quality of life outcomes as seen in AIS patients.

Background: Adult spinal deformity (ASD) surgery often involves the placement of pedicle screws using various methods, including freehand technique, fluoroscopic guidance, and computer-assisted intraoperative navigation, each with distinct limitations. Particularly challenging is the instrumentation of pedicles with small or absent cancellous channels (Watanabe types C and D pedicles), commonly found at the apex of large curves where precise screw placement is crucial for effective deformity correction. 3D-printed pedicle screw drill guides (3DPSG) may assist in accurately placing pedicle screws while minimally disrupting the standard ASD surgery workflow.
