Technical Considerations for the Hypothenar Fat Pad Flap

Technique for Hypothenar Fat Pad Flap
  • 1.

    Perform after an extensile carpal tunnel release

  • 2.

    Mobilize ulnarly based adipose flap of approximately 4 cm x 3 cm from the hypothenar eminence

  • 3.

    Leave a thin layer of adipose tissue on the dermis to maintain adequate vascularity of the skin

  • 4.

    Flap should provide complete coverage of the neurolyzed median nerve

  • 5.

    Secure the flap to the radial leaf of the TCL using absorbable horizontal mattress sutures

TCL, transverse carpal ligament.
