**5. Conclusions**

Surgical treatment of both-column fractures of the acetabulum using intraoperative adjustable traction with a limb positioner is considered an effective and safe method because it allows continuous traction with constant force throughout the surgery and without any traction-related complications. It also helps to reduce and stabilize the fracture, reduces the number of required operating room personnel, and yields favorable radiologic and functional outcomes.
