Area of Science:

  • Orthopedic Surgery
  • Plastic Surgery
  • Reconstructive Surgery

Background:

  • The deltoid muscle is a well-vascularized tissue source.
  • It serves as a reliable option for obliterating wounds, especially those involving the glenohumeral joint.
  • The deltoid muscle is a homologue of the gluteus maximus muscle.

Observation:

  • The deltoid muscle possesses two independent dominant vascular pedicles, classifying it as a type III muscle flap.
  • It can be vertically divided into two hemideltoid flaps.
  • One portion can be preserved with intact innervation to maintain arm abduction function.

Findings:

  • The hemideltoid flap provides a viable option for wound coverage.
  • Preserving innervation in one portion maintains the critical function of arm abduction.

  • The muscle's expendability is limited, making preservation of function crucial.

    • Implications:

    • The hemideltoid flap is a valuable reconstructive tool for specific shoulder defects.
    • Its ability to maintain arm function makes it advantageous over expendable tissue transfers.
    • Limitations in the arc of rotation necessitate consideration of alternative methods for larger shoulder defects.
