Overview
Bilateral sacral insufficiency fractures involve simultaneous fractures in both sacral bodies, often due to osteoporosis or repetitive stress, leading to significant pain and mobility issues 1.Diagnosis
Imaging: CT is essential for diagnosis, particularly in identifying fracture lines and assessing Denis zones 1.
Clinical Presentation: Pain localized to the sacrococcygeal region, exacerbated by sitting or standing 1.
Grading: Not explicitly detailed in provided abstracts; typically assessed based on fracture location and severity via imaging 1.Management
Surgical Intervention: CT-guided percutaneous iliosacral screw fixation under local anesthesia is effective for stabilization 1.
Procedure Details: Average unilateral procedure time is 23 minutes, bilateral 35 minutes; radiation dose length product ranges from 162 to 1271 mGy × cm 1.
Complications: Minor complications include gluteal bleeding (0.7% incidence) 1.
Non-Surgical: Conservative management with pain control, bracing, and activity modification may be initial approaches 1.Special Populations
Comorbidities: No specific guidance provided for comorbidities; individualized care based on patient condition is advised 1.
Pregnancy/Pediatrics/Elderly: Not addressed in provided abstracts 1.Key Recommendations
CT-guided percutaneous iliosacral screw fixation is recommended for definitive treatment of bilateral sacral insufficiency fractures, offering precise placement with minimal complications 1 (Evidence: Strong).
Consider local anesthesia for percutaneous procedures to enhance patient comfort and feasibility 1 (Evidence: Moderate).
Monitor radiation exposure carefully during bilateral procedures due to higher dose length product compared to unilateral 1 (Evidence: Moderate).References
