[Classification and Treatment of Sacroiliac Joint Dislocation]

Area of Science:

• Orthopedic Surgery
• Trauma Management
• Pelvic Fractures

Background:

• Sacroiliac joint dislocation presents complex challenges in diagnosis and treatment.
• Existing classification systems may not fully capture the nuances of these injuries.
• Effective management is crucial for restoring function and preventing long-term complications.

Purpose of the Study:

• To introduce a novel classification system for sacroiliac joint dislocations.
• To establish tailored treatment regimens for each identified type of dislocation.
• To evaluate the clinical efficacy of the proposed classification and treatment strategy.

Main Methods:

• A new classification system categorizing sacroiliac joint dislocations into four types based on dislocation direction, associated iliac/sacral fractures, and morphology.
• Specific surgical approaches and fixation techniques were applied according to the classified type (e.g., anterior iliac fossa approach, posterior sacroiliac joint approach, percutaneous screws, reconstruction plates, spinal pelvic fixation).
• Prospective follow-up of patients for 24 to 72 months to assess outcomes.

Main Results:

• 100% patient survival, wound healing, and fracture healing rates were observed.
• Type I dislocations (anterior) showed complete recovery in 12 months.
• Type II (posterior) and Type III (crescent) dislocations also demonstrated successful outcomes, with most patients recovering fully.
• Type IV dislocations had a high success rate, with one case of partial neurological recovery.

Conclusions:

• The developed classification and treatment regimen for sacroiliac joint dislocation significantly improve therapeutic outcomes.
• This evidence-based approach offers a reliable and effective method for managing sacroiliac joint injuries.
• The findings support the widespread adoption and promotion of this renewed classification and treatment strategy.
