Assessment and Fixation Strategies for the Unstable Volar Lunate Facet

Area of Science:

• Orthopedic Surgery
• Anatomy
• Radiology

Background:

• Unstable distal radius fractures often involve intra-articular fragments.
• The volar lunate facet is a critical component of the distal radius articular surface.
• Failure to adequately fix this fragment can lead to carpal instability and poor outcomes.

Purpose of the Study:

• To review the anatomy and imaging relevant to distal radius fractures with unstable volar lunate facet fragments.
• To outline surgical approaches for exposing the critical corner.
• To discuss various fixation strategies for stabilizing the volar lunate facet.

Main Methods:

• Literature review focusing on anatomy, imaging, and surgical techniques.
• Analysis of fracture patterns involving the volar lunate facet.
• Discussion of established and novel fixation methods.

Main Results:

• Understanding volar lunate facet anatomy is key to successful fracture management.
• Appropriate imaging is essential for evaluating fragment displacement and planning fixation.
• Multiple surgical strategies exist for stabilizing this critical fragment.

Conclusions:

• Accurate reduction and stable fixation of the volar lunate facet are paramount in treating unstable distal radius fractures.
• Proper surgical technique and implant selection can improve patient outcomes.
• This review provides a guide for surgeons managing these complex injuries.
