Sacral Insufficiency Fractures: Pathology, Management, and Outcomes.

Area of Science:

• Orthopedics
• Geriatrics
• Radiology

Background:

• Sacral insufficiency fractures are increasingly common in elderly patients with osteoporosis.
• These fractures are linked to significant morbidity and mortality.

Purpose of the Study:

• To review current treatment options for sacral insufficiency fractures.
• To highlight the importance of prompt diagnosis and appropriate management based on fracture stability.

Main Methods:

• Review of nonoperative measures, pharmacologic therapies, procedural treatments (e.g., sacroplasty), and operative management.
• Discussion of fixation techniques like percutaneous posterior pelvic ring screws.

Main Results:

• Treatment choice depends on symptom severity and fracture instability.
• Sacroplasty shows potential but lacks comparative studies and has concerning complication rates.
• Percutaneous screws offer stable fixation for early mobilization, though screw backout is a concern with standard techniques.

Conclusions:

• Effective management of sacral insufficiency fractures can decrease patient morbidity.
• Limited comparative data exist for procedural and operative techniques.
• Further research is needed to compare outcomes of different treatment modalities.
