Which radial head fractures are best treated surgically?

Area of Science:

• Orthopedic Surgery
• Traumatology
• Biomechanics

Background:

• Radial head fractures are common elbow injuries.
• The radial head is crucial for elbow stability, particularly in varus-valgus and posterolateral rotatory directions.
• Instability can be exacerbated in elbows with ligamentous deficiencies.

Purpose of the Study:

• To review current literature on surgical indications for radial head fractures.
• To provide evidence-based guidance on managing these injuries.
• To clarify decision-making processes for surgical intervention.

Main Methods:

• Comprehensive review of existing scientific literature.
• Analysis of factors influencing surgical decisions, including fracture patterns and associated injuries.
• Synthesis of current treatment guidelines and expert opinions.

Main Results:

• Surgical decisions depend on fracture pattern and associated injuries.
• Comminution and loss of cortical contact correlate with higher rates of associated injuries.
• Nondisplaced fractures are managed non-operatively with early mobilization.
• Displacement >2 mm without mechanical block is not a clear surgical indication.
• Mechanical block and comminution are key surgical indications.

Conclusions:

• Clear criteria are needed for surgical intervention in radial head fractures.
• Associated injuries and mechanical limitations significantly influence treatment choices.
• This review offers guidance for optimizing surgical decision-making in radial head fractures.
