Forearm transplantation osteosynthesis using modified ulnar shortening osteotomy technique

Area of Science:

• Orthopedic surgery
• Hand transplantation
• Limb reconstruction

Background:

• Forearm hand transplantation presents challenges in achieving ulna bone union.
• Factors include extensive soft tissue dissection, immunosuppressive medications, and diaphyseal osteotomy.
• Conventional techniques may not optimize osseous healing.

Purpose of the Study:

• To present a modified surgical technique for elective ulnar shortening osteotomy.
• To address the challenges of achieving osseous union in forearm hand transplantation.
• To provide a detailed description and case example of the modified technique.

Main Methods:

• Modification of the conventional ulnar shortening osteotomy.
• Utilizing precise osteotomy alignment.
• Employing an oblique osteotomy with a large contact surface.
• Implementing lag screw and compression plating.

Main Results:

• The modified technique offers precise alignment and enhanced bone contact.
• Facilitates stable fixation for osseous union.
• Demonstrated successful application in a case example.

Conclusions:

• The modified ulnar shortening osteotomy technique is advantageous for forearm hand transplantation.
• It enhances the potential for successful osseous union of the ulna.
• This modification offers a valuable approach for reconstructive surgery.
