Area of Science:

  • Anatomy
  • Surgical Research

Background:

  • Functional muscle transfer is crucial in reconstructive surgery.
  • Identifying novel donor sites is essential for improving outcomes.

Purpose of the Study:

  • To investigate the neurovascular anatomy of the sartorius muscle.
  • To assess its viability as a donor site for functional muscle transfer.

Main Methods:

  • Detailed dissection and radiographic analysis of 42 human sartorius muscle specimens (fresh and preserved).
  • Vascular injection in fresh cadavers to delineate neurovascular pedicles.

Main Results:

  • Each nerve to the sartorius muscle has an accompanying vascular pedicle, forming a neurovascular hilum.
  • Intramuscular nerves and vessels branch early, running parallel to muscle fibers.
  • An intricate vascular network with numerous anastomoses was observed.

Conclusions:

  • The sartorius muscle's neurovascular supply supports its subdivision into functional units.
  • Segmental muscle flaps with intact neurovascular pedicles can be harvested from the sartorius muscle for transfer.
