Distal radioulnar joint arthroplasty. Current concepts

Area of Science:

• Orthopedic Surgery
• Musculoskeletal System Research

Background:

• The distal radioulnar joint (DRUJ) is crucial for forearm rotation and wrist stability.
• Various arthroplasty techniques exist for DRUJ reconstruction, each with specific indications.
• Understanding DRUJ biomechanics is key to selecting the appropriate surgical approach.

Purpose of the Study:

• To provide a theoretical framework for choosing among different DRUJ arthroplasty techniques.
• To evaluate the efficacy and evolution of the author's hemiresection interposition arthroplasty technique.
• To discuss the primary indications and alternatives for hemiresection arthroplasty.

Main Methods:

• Review of existing arthroplasty techniques for the distal radioulnar joint.
• Analysis of the theoretical basis for technique selection.
• Assessment of long-term results and modifications of the hemiresection interposition arthroplasty.

Main Results:

• Arthroplasty techniques are categorized into resectional, hemiresectional, ulnar shortening, and replacement.
• The hemiresection interposition technique, developed in the mid-1970s, has demonstrated sufficient efficacy.
• Experience has revealed specific problems and necessary modifications for the hemiresection technique.

Conclusions:

• A thorough understanding of distal radioulnar joint function simplifies the choice of arthroplasty.
• The hemiresection arthroplasty and its alternatives are essential components in managing DRUJ pathology.
• Ongoing experience refines the application and outcomes of DRUJ arthroplasty procedures.
