Pedicled Oblique Para-Umbilical Perforator (OPUP) Flap for Upper Limb Reconstruction

Background: Groin flap has been considered the workhorse flap for hand reconstruction. However it has certain drawbacks when covering defects over elbow or proximal forearm. Pedicled oblique paraumbilical perforator (OPUP) based flaps provide a good alternative in such cases.

Methods: We performed OPUP flap in 11 cases of complex upper limb reconstructions over the past one year. We report our experience with this flap.

Results: All flaps survived. One patient had marginal necrosis of 1 cm in the proximal end after flap division. Three patients had donor site scar hypertrophy.

Conclusions: OPUP flap is superior to groin flap for larger defects or defects around the elbow. The major disadvantage is the donor site scar which is prone to hypertrophy.
