Transradial Amputation With Nerve Management: Case Presentation and Surgical Technique

Area of Science:

• Orthopedic Surgery
• Neurology
• Prosthetics & Artificial Limbs

Background:

• Transradial amputation preserves forearm rotation but often results in persistent phantom limb pain and neuropathic issues.
• Current amputation techniques may not fully address nerve-related complications or optimize prosthetic integration.

Purpose of the Study:

• To describe a multidisciplinary approach for transradial amputation integrating advanced nerve management and prosthetic-informed surgical planning.
• To evaluate the efficacy of targeted muscle reinnervation and regenerative peripheral nerve interfaces in managing pain and enhancing prosthetic use.

Main Methods:

• A 29-year-old male patient with a ballistic injury underwent transradial amputation.
• Surgical techniques included targeted muscle reinnervation (TMR), regenerative peripheral nerve interfaces (RPNI), and myodesis.
• Limb length was preserved according to prosthetic guidelines.

Main Results:

• The integrated approach aimed to optimize pain control and prosthetic success.
• Myodesis was performed to enhance residual limb stability and myoelectric signal quality.
• The case highlights improved functional outcomes and quality of life.

Conclusions:

• Transradial amputation, when performed with appropriate length, aids prosthetic use.
• Advanced nerve management and prosthetic-informed surgery are crucial for optimizing outcomes.
• This multidisciplinary strategy offers a promising model for traumatic transradial amputations.
