Summary
This summary is machine-generated.

Targeted muscle reinnervation (TMR) offers a surgical solution for upper extremity amputees, improving prosthetic control and alleviating phantom limb pain. This technique coapts peripheral nerves to muscle targets, enhancing myoelectric signals and treating neurogenic pain.

Area of Science:

  • Surgical innovation
  • Regenerative medicine
  • Prosthetics and Bionics

Background:

  • Targeted muscle reinnervation (TMR) is a surgical technique involving nerve coaptation.
  • Originally developed to improve myoelectric prosthetic control in amputees.
  • Accidental discovery of TMR's efficacy in treating phantom and residual limb pain.

Purpose of the Study:

  • To review current literature on TMR in upper extremity amputees.
  • To detail TMR techniques applicable to various amputation levels.
  • To provide recommendations for TMR implementation in clinical practice.

Main Methods:

  • Review of existing scientific literature on TMR.
  • Analysis of surgical techniques for different upper extremity amputation levels.
  • Synthesis of authors' clinical experience and recommendations.

Main Results:

  • TMR enhances myoelectric signal acquisition for prosthetic use.
  • TMR effectively treats and prevents phantom and residual limb pain.
  • TMR can be performed at any amputation level, either during initial surgery or delayed.

Conclusions:

  • TMR is a valuable consideration for all upper extremity amputees.
  • Multidisciplinary limb salvage teams are crucial for optimal TMR outcomes.
  • Further research and standardized techniques can enhance TMR's benefits.
