Posterior transiliac plating effectively stabilizes vertically unstable pelvic fractures. This method achieved good or excellent reduction and clinical outcomes in most patients, with systematic bone consolidation.
Area of Science:
- Orthopedic Surgery
- Trauma Surgery
- Pelvic Fracture Management
Background:
- Vertically unstable pelvic fractures pose significant treatment challenges.
- Effective surgical fixation is crucial for optimal patient recovery and functional outcomes.
Purpose of the Study:
- To describe the posterior transiliac plating technique.
- To report acute-phase clinical and radiological results for this method in vertically unstable pelvic fractures.
Main Methods:
- A technical note detailing the posterior transiliac plating procedure.
- Evaluation of 10 consecutive patients with vertically unstable pelvic fractures.
Main Results:
- Good or excellent reduction in 70% of cases.
- Good or excellent clinical results (Hannover and Majeed scores) in 80% of patients, with a mean Majeed score of 71.8.
- Systematic bone consolidation observed at final follow-up.
- Complications included early sepsis (3 cases) and hardware removal (4 cases).
Conclusions:
- Posterior transiliac plating offers immediate and effective fixation for vertically unstable pelvic fractures.
- Timely surgical intervention and minimal initial displacement correlate with better reduction outcomes.

Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
