Sequential reduction and fixation for windswept pelvic ring injuries (LC3) corrects the deformity until healed

Area of Science:

• Orthopedic Surgery
• Trauma Management
• Pelvic Fracture Repair

Background:

• Windswept type pelvic injuries present significant challenges in restoring normal anatomy.
• Effective fixation strategies are crucial for successful outcomes in these complex cases.

Purpose of the Study:

• To describe a stepwise surgical technique for the reduction and fixation of windswept type pelvic injuries.
• To evaluate the efficacy of this method in restoring pelvic anatomy.

Main Methods:

• A sequential surgical approach was employed, starting with posterior stabilization using a partially threaded SI screw.
• Anterior reduction and fixation were achieved using internal fixators, external fixators, or plates.
• A fully threaded SI screw was used for compression and stabilization of the sacral fracture.

Main Results:

• The Keshishyan deformity index showed significant correction from a mean of 0.0456 pre-operatively to 0.0170 post-operatively.
• An average correction of 62% was maintained at the latest follow-up (15 months).
• Statistical analysis confirmed significant improvement from pre-operative to post-operative and follow-up measurements.

Conclusions:

• The described stepwise technique is an effective method for correcting and maintaining reduction in windswept type pelvic injuries.
• This approach offers a reliable solution for this rare and difficult-to-treat fracture pattern.
