However, these screws are associated with unique surgical complications, including dislocation during tightening. Summary: This letter reports a case involving a 21-year-old male who experienced the dislocation of a PAPS head during the tightening process for lumbar stabilization following a burst fracture. The incident resulted in no adverse sequelae, and the operation was completed successfully with the replacement of the dislocated screw. Conclusion: The case highlights the necessity of verifying the integrity of surgical implants prior to use and underscores the importance of manufacturers ensuring product quality. Device component failure should be recognized as a potential risk in spinal surgery, necessitating reporting to relevant authorities.
