Arthroscopic Capitate Partial Resection for Kienböck Disease: Postoperative Outcomes

Area of Science:

• Orthopedic surgery
• Hand surgery
• Wrist biomechanics

Background:

• Kienböck disease involves avascular necrosis of the lunate.
• Increased load on the lunate contributes to disease progression.
• Current treatments may have limitations in load reduction or joint preservation.

Purpose of the Study:

• To present a surgical technique for Kienböck disease.
• To evaluate partial capitate shortening osteotomy for lunate load reduction.
• To assess the preservation of the scaphoid-capitate articular surface.

Main Methods:

• Arthroscopic partial resection of the proximal capitate articular surface.
• Procedure designed to decrease pressure transmitted to the lunate.
• Focus on maintaining the integrity of the scaphoid-capitate articulation.

Main Results:

• The presented technique offers a feasible approach to reduce lunate load.
• Preservation of the scaphoid-capitate articular surface is achieved.
• Alleviation of pressure on the lunate is the primary outcome.

Conclusions:

• Partial capitate shortening osteotomy is a promising surgical option for Kienböck disease.
• This arthroscopic method effectively reduces load on the lunate.
• The technique allows for preservation of critical joint surfaces.
