Innervated Muscle Transfer for Dynamic Abdominal Wall Reconstruction: Principles, Techniques, and Outcomes

Abdominal wall defects (AWDs) represent a significant reconstructive challenge, necessitating restoration of both structural integrity and dynamic function. While static reconstruction can address structural deficits, it often fails to replicate the dynamic properties of the native abdominal wall musculature, potentially resulting in compromised core strength and increased hernia recurrence. This article reviews the principles and techniques of dynamic abdominal wall reconstruction utilizing innervated muscle transfer, emphasizing its advantages in restoring core strength, minimizing hernia recurrence, and improving overall functional outcomes, particularly in complex cases. We will outline surgical planning, donor site selection, operative techniques, and reported clinical outcomes.
