Summary
Retrograde locked nailing offers a novel solution for pubic ramus fractures, overcoming limitations of traditional screwing methods. This technique enables immediate weight-bearing in pelvic ring fracture patients.
Area of Science:
- Orthopedic surgery
- Traumatology
- Skeletal fixation devices
Background:
- Percutaneous screwing of pubic ramus fractures has limitations, including narrow or curved bone corridors and lack of proximal locking.
- These limitations can lead to implant mobilization and surgical challenges.
Purpose of the Study:
- To present an original method for percutaneous fixation of pubic ramus fractures using retrograde locked nailing.
- To evaluate the feasibility and outcomes of this technique in patients with pelvic ring fractures.
Main Methods:
- Utilized the fibula rod system (Acumed), a proximally locking fibula nail, for retrograde locked nailing.
- Applied the technique for anterior fixation in four patients with pelvic ring fractures.
- Assessed suitability in cases where a 6.5 mm cannulated screw corridor was not feasible.
Main Results:
- Successful application of retrograde locked nailing in four patients with pelvic ring fractures.
- All patients achieved immediate weight-bearing post-surgery.
- No intraoperative or postoperative complications were reported.
Conclusions:
- Retrograde locked nailing provides a viable alternative for anterior pelvic ring fixation, addressing limitations of conventional screwing.
- Further research with larger patient cohorts and extended follow-up is needed to confirm fracture consolidation.
