Arthroscopic Proximal Row Carpectomy Using the Volar Central Portal

Area of Science:

• Orthopedic Surgery
• Arthroscopy
• Wrist Anatomy

Background:

• Proximal row carpectomy (PRC) is a recognized treatment for wrist degeneration and Kienböck disease.
• Traditionally performed as an open procedure, arthroscopic techniques are emerging.
• Open PRC involves significant soft tissue disruption.

Purpose of the Study:

• To describe an arthroscopic approach to proximal row carpectomy.
• To highlight the advantages of arthroscopic PRC over open techniques.
• To evaluate the feasibility and benefits of this minimally invasive wrist surgery.

Main Methods:

• Arthroscopic proximal row carpectomy utilizing a volar central portal as a third portal.
• Minimally invasive technique preserving dorsal and volar ligaments.
• Simultaneous instrument use for efficiency.

Main Results:

• Reduced damage to wrist ligaments and capsule.
• Potential for earlier patient mobilization and decreased postoperative stiffness.
• Lower risk of interosseous posterior nerve injury and preserved proprioception.

Conclusions:

• Arthroscopic PRC is a viable alternative to open surgery for specific wrist pathologies.
• The technique offers potential benefits including reduced surgical trauma and improved functional recovery.
• Further studies are warranted to compare long-term outcomes.
