Interpolation Pedicle Flap Technique in Wound Defect with Tibial Bone Exposed: A Case Report

Interpolation flap is a flap constructed from nonadjacent donor tissue that carry an inherent blood supply (vascular pedicle). They are ideally suitable for reconstruction of large or deep defect. These flaps have their own blood supply therefore they are more likely to survive on exposed bone or cartilage. The use of these technique should result in a bridge of tissue, or pedicle, between the flap base and the surgical defect. A 61-years-old man admitted to the emergency unit 2 hours ago after a traffic accident. Physical examination shows crush injuries on the right lower limb with open wounds exposing the muscles, tendons, and bone. In the distal neurovascular (NVD) obtained capillary refill time < 2 seconds, limited active movement due to pain, and good sensory. After the initial treatment of external fixation and debridement, a week follow up found a wound defect on the medial side of the leg around 10 x 15 cm with tibial bone exposed as a base of wound defect. The usage of Pedicle Interpolation Flap Technique is a better choice to delayed treatment for soft tissue defect with bone exposed. The anatomy of artery is essential as a requirement to obtain the flap needed. Fine and holistic care of the flap shall increase the success rate of regaining and retaining anatomical and physiological, as well as cosmetic, and exponentially lower the probability of complications occurrence by accurate planning and hand in hand care to better strength, motion and functional outcome.
