[Radial Head Arthroplasty: Pearls and Pitfalls]

Area of Science:

• Orthopedic Surgery
• Traumatology
• Biomedical Engineering

Background:

• Radial head fractures are frequent upper extremity injuries, often linked to complex trauma.
• The Mason/Johnston system classifies these fractures.
• Increasing incidence necessitates effective treatment strategies.

Purpose of the Study:

• To review indications for radial head arthroplasty.
• To detail surgical approaches and implantation techniques.
• To discuss and provide strategies for managing common complications.

Main Methods:

• Review of case reports.
• Analysis of prosthetic designs (polarity, modularity, fixation).
• Discussion of surgical techniques and complication management.

Main Results:

• Radial head arthroplasty is indicated when fractures are non-reconstructable or osteosynthesis fails.
• Various prosthetic designs and fixation methods (cemented, cementless, intentionally loose) exist.
• Common pitfalls include stiffness, instability, and overstuffing.

Conclusions:

• Radial head arthroplasty is a viable option for complex radial head fractures.
• Careful consideration of prosthetic design and surgical technique is crucial.
• Proactive management of potential complications is essential for optimal outcomes.
