Which ankle fractures require syndesmotic stabilization?

Area of Science:

• Orthopedic Surgery
• Biomechanics
• Sports Medicine

Background:

• Ankle fractures frequently involve syndesmotic ruptures, crucial for ankle mortise stability.
• Common causes include foot external rotation, talar eversion, and excessive dorsiflexion.
• Current clinical practice lacks uniform guidelines for syndesmotic screw use in specific ankle fracture patterns.

Purpose of the Study:

• To review existing literature on syndesmotic ruptures and ankle fractures.
• To formulate evidence-based recommendations for syndesmotic screw placement.
• To guide clinical decision-making for orthopedic surgeons treating ankle injuries.

Main Methods:

• Systematic literature review of biomechanical and clinical studies.
• Analysis of injury patterns and fracture types associated with syndesmotic ruptures.
• Synthesis of data to develop clinical practice guidelines.

Main Results:

• Identification of key injury mechanisms leading to syndesmotic rupture.
• Evaluation of the efficacy and indications for syndesmotic screw fixation.
• Summary of factors influencing the decision for syndesmotic screw placement.

Conclusions:

• Standardized recommendations for syndesmotic screw use are needed.
• Evidence-based guidelines can improve outcomes for ankle fractures with syndesmotic injury.
• Further research may refine indications for syndesmotic fixation.
