Application of Suspension Fixation with Button Plates for Patients with Distal Radioulnar Joint Dislocation: A Case...

Area of Science:

• Orthopedic Surgery
• Musculoskeletal System
• Trauma Surgery

Background:

• Distal radioulnar joint (DRUJ) dislocations pose significant challenges in wrist function.
• Current reconstruction methods may involve complex procedures with potential complications.

Purpose of the Study:

• To evaluate the efficacy of suspension fixation using button plates for DRUJ dislocation.
• To assess the functional and radiographic outcomes of this surgical technique.

Main Methods:

• A case series of six patients with DRUJ dislocations treated with suspension fixation and button plates.
• Evaluation included physical examination, radiography, MRI, and functional wrist assessments (Garland-Werley, Mayo, VAS) pre- and post-operatively.
• Follow-up was conducted every 3 months for 12 months.

Main Results:

• Significant improvements were observed in wrist range of motion, grip strength, and functional scores (Garland-Werley, Mayo, VAS) at 12 months post-surgery.
• Radiographic evaluation confirmed stable fixation and no DRUJ redislocation.
• No device removal, secondary fractures, or nerve injuries were reported.

Conclusions:

• Suspension fixation with button plates is a simple, minimally invasive technique for DRUJ dislocation reconstruction.
• It provides DRUJ stability, allows early mobilization, and leads to satisfactory functional recovery.
• This method avoids the need for intra-articular or extra-articular ligament reconstruction.
