Percutaneous spinopelvic fixation technique using external fixation for focal kyphosis reduction in U-type sacral fractures: a case report

This case highlights the successful management of a displaced U-type sacral fracture with focal kyphosis using a percutaneous spinopelvic external fixator-based reduction technique. A minimally invasive approach can achieve significant reduction in deformity while minimizing soft tissue complications, making it viable for patients with complex medical histories. The clinical impact includes improved postoperative recovery and reduced risk of long-term disability. This case underscores the importance of individualized surgical planning and the potential benefits of percutaneous techniques in managing complex sacral fractures.
