Can we regrow a human arm? A negative perspective from an upper-limb surgeon

Area of Science:

• Biomedical Engineering
• Regenerative Medicine
• Clinical Application

Background:

• The concept of regrowing a human arm is explored within biomedical research.
• Clinical utility must guide research priorities and resource allocation.

Purpose of the Study:

• To critically evaluate the feasibility and clinical necessity of human arm regeneration.
• To determine the most effective strategies for addressing upper limb loss.

Main Methods:

• Literature review and critical analysis of current regenerative medicine capabilities.
• Comparative assessment of proposed regenerative approaches versus existing prosthetic and surgical solutions.

Main Results:

• Human arm regeneration is currently not feasible and faces significant biological hurdles.
• Existing technologies like bionic arms and advanced reconstructive surgery offer practical and effective solutions for limb loss.

Conclusions:

• The focus of research should transition from improbable regeneration to functional restoration of lost limbs.
• Prioritizing the development and application of bionic prosthetics and reconstructive surgery is clinically indicated.
