Leg dominance does not influence anterolateral thigh (ALT) free flap harvest. Preoperative imaging is recommended for selecting the best donor thigh due to significant individual variations in perforator anatomy.
Area of Science:
- Microsurgery
- Plastic Surgery
- Anatomy
Background:
- Anterolateral thigh (ALT) free flap harvest requires detailed perforator anatomy knowledge.
- Donor site selection may involve preoperative imaging and practical factors.
- Leg dominance's impact on perforator quantity is uncertain.
Purpose of the Study:
- To investigate if leg dominance influences perforator number and anatomy for ALT free flap harvest.
- To compare muscle mass and perfusion between dominant and nondominant legs.
- To guide donor thigh selection for ALT free flaps.
Main Methods:
- Color-coded duplex sonography and infrared thermography used to locate ALT perforators in 24 subjects.
- Perforator number, subcutaneous tissue, and muscle thickness assessed bilaterally.
- Comparison between dominant and nondominant legs.
Main Results:
- No significant difference in perforator numbers or hot spots between dominant and nondominant legs.
- High interindividual variability in perforator quantity observed.
- No significant difference in subcutaneous tissue or muscle thickness.
Conclusions:
- No evidence supports preferring the dominant or nondominant leg for ALT free flap harvesting.
- High interindividual differences necessitate reliance on preoperative imaging for donor thigh selection.

Muscles that Move the Thigh
Three other significant muscles are the gluteus maximus, gluteus medius, and gluteus minimus. The gluteus maximus originates from the posterior surface of the ilium, sacrum, and coccyx, and the thoracolumbar...

Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...
