Reversed posterior interosseous flap: safe and easy method for hand reconstruction

Area of Science:

• Orthopedic Surgery
• Plastic Surgery
• Microsurgery

Background:

• Complex hand trauma requires specialized surgical techniques for soft tissue defect coverage.
• Assessing the most appropriate coverage method is crucial for optimal hand function.
• The reversed posterior interosseous flap is explored as a reconstructive option.

Purpose of the Study:

• To evaluate the efficacy of the reversed posterior interosseous flap for hand defect coverage.
• To assess the flap's suitability for various hand and wrist injuries.
• To report outcomes including flap survival and donor site healing.

Main Methods:

• Retrospective case series analysis.
• Application of the reversed posterior interosseous flap for soft tissue defects.
• Inclusion of injuries to the dorsum of the hand, wrist, and dorsal thumb.
• Skin grafting of all donor sites.

Main Results:

• The reversed posterior interosseous flap was used in 15 cases (10 dorsum, 3 wrist, 2 dorsal thumb).
• All flaps survived completely without any signs of venous compromise.
• All donor sites healed successfully following skin grafting.

Conclusions:

• The reversed posterior interosseous flap is a versatile and reliable option for covering moderate-sized defects of the hand.
• It is particularly indicated for injuries involving the wrist, dorsal hand, and dorsal thumb.
• This flap provides a successful reconstructive solution for complex hand trauma.
