Fracture dislocation distal radioulnar joint — Clinical Guidelines

Overview

Fracture dislocation of the distal radioulnar joint (DRUJ) involves injury to the joint where the radius and ulna meet at the wrist, often leading to instability and functional impairment. 4

Diagnosis

Clinical Presentation: Pain, swelling, limited range of motion, and instability during forearm rotation. 4

Imaging: Radiographs essential for initial assessment; MRI or CT may be needed for detailed evaluation of soft tissue injuries and joint congruity. 4

Grading: Classification systems for instability exist but vary; clinical observation and experimental data guide understanding 4.

Management

Surgical Intervention:

- Sauvé-Kapandji Procedure: Fusion of the DRUJ using a bone peg; effective in several cases but monitor for complications like pseudoarthrosis 3. - Adipofascial Flap: Used for osteoarthritis management post-DRUJ injury, though evidence is Level IV 1.

Conservative Treatment: Immobilization with splinting, followed by gradual mobilization and physiotherapy to restore function 4.

Special Populations

Pediatrics: No specific data provided in abstracts.

Elderly: Considerations for surgical risks and rehabilitation needs are implied but not detailed 3.

Comorbidities: No specific guidance provided regarding comorbidities affecting management 3.

Key Recommendations

Surgical Fusion for Severe Instability: Consider the Sauvé-Kapandji procedure for severe DRUJ instability, particularly when conservative measures fail 3 (Evidence: Moderate).

Imaging for Comprehensive Assessment: Utilize advanced imaging techniques (MRI, CT) alongside radiographs for a thorough evaluation of DRUJ injuries 4 (Evidence: Moderate).

Gradual Rehabilitation Post-Injury: Implement a structured program of immobilization followed by physiotherapy to optimize functional recovery 4 (Evidence: Moderate).
