Pelvic unlocking closed reduction device for treatment of severe traumas combined with pelvic fractures: a retrospective case series of 13 patients

For patients with severe trauma combined with pelvic fracture, the pelvic unlocking and reduction device can be used for minimally invasive internal fixation at an early stage as long as their vital signs are stable. In this study, we summarized and advocated the 'turn-back order' reduction and internal fixation philosophy of 'posterior-ring unlocking - anterior ring to posterior ring reduction stabilization - posterior ring to anterior ring internal fixation placement' in pelvic closed reduction and internal fixation surgery.
