Rigid internal fixation of displaced distal radius fractures

Area of Science:

• Orthopedic Surgery
• Biomechanics
• Surgical Innovation

Background:

• Distal radius fractures are the most common long bone fractures.
• Current treatments include closed reduction, percutaneous pinning, external fixation, and open reduction and internal fixation.

Observation:

• A novel minimally invasive intramedullary fixation technique using a partially flexible rod is presented.
• The technique involves a small incision, awl and reamer use, and implant placement within the radial intramedullary canal.
• Sensory branches of the radial nerve are carefully retracted during the procedure.

Findings:

• The described technique allows for fracture stabilization with screws placed under the distal radial articular margin.
• Patients are immobilized in a wrist splint for 2 to 4 weeks post-surgery.
• Case examples demonstrate excellent radiographic outcomes, improved postoperative motion, and functional recovery.

Implications:

• This minimally invasive approach is well-suited for distal radius fractures not involving the articular surface.
• The technique offers a safe and effective alternative with promising results.
• Further research may explore its application in a broader range of distal radius fractures.
