Summary
Percutaneous pelvic screwing (PPS) offers a minimally invasive approach for pelvic fractures and tumor fixation, with evolving indications and lower morbidity than open surgery. Careful preoperative planning using CT imaging is crucial for successful outcomes.
Area of Science:
- Orthopedic Surgery
- Minimally Invasive Techniques
- Medical Imaging
Background:
- Percutaneous pelvic screwing (PPS) is an evolving technique for pelvic fracture fixation and tumor lesion stabilization.
- It offers lower morbidity compared to traditional open surgery.
- Advancements in imaging have expanded its indications.
Purpose of the Study:
- To review the indications, planning, and outcomes of percutaneous pelvic screwing.
- To highlight the role of preoperative planning and emerging technologies.
Main Methods:
- Review of percutaneous pelvic screwing techniques, including posterior (iliosacral, trans-sacral, supra-acetabular) and anterior (pubic ramus, iliac wing, gluteal pillar) approaches.
- Emphasis on preoperative planning using CT DICOM viewer software for multiplane reconstruction and 3D analysis.
- Discussion of percutaneous acetabular screwing (transverse acetabular, retrograde posterior column).
Main Results:
- PPS provides fixation for various pelvic ring fractures and tumor lesions, applicable to young and older patients.
- Results are comparable to open surgery with significantly reduced morbidity.
- Common complications include malpositioning and fixation failure.
Conclusions:
- Rigorous preoperative planning is essential for successful PPS.
- Innovations like 3D printing, navigation, and robotic surgery are shaping the future of PPS.
- Intraoperative imaging and navigation can enhance safety and reduce pitfalls.
