| Introduction|| |
The foot is a multijointed mechanical structure that is critical to the biomechanical function of the lower extremity. The reconstruction of dorsal defects of the distal foot and the great toe can be problematic surgically due to poor vascularity, limited skin laxity, and mobility. In this study, we present a useful salvage method with the first dorsal metatarsal artery adipofascial perforator flap for traumatic injuries of dorsal defects of the distal foot.
| Case History and Surgical Technique|| |
A 58-year-old male patient was admitted with a crush injury around the first dorsal metatarsal joint. Skin and soft-tissue defects were formed around the first metatarsophalangeal joint, extending to the dorsal of the first finger. The extensor hallucis longus tendon and metatarsophalangeal joint were exposed.
The proximal border of the defect and the distal border of the extensor retinaculum were marked. A Doppler was used to locate the distal perforator of the first dorsal metatarsal artery. A skin incision was made between the two landmarks. The adipofascial flap was elevated from proximal to distal. The proximal perforator branches were ligated. The flap was elevated to the Doppler-determined location and the distal perforator was skeletonized. We kept above the paratenon plane to preserve tendon vascularization. The superficial peroneal nerve was preserved. The flap was turned over into a defect. The venous drainage was maintained by the superficial dorsal venous network and the dorsal metatarsal veins. A split-thickness skin graft was adapted over the flap. The donor area was primarily sutured [Figure 1] and [Figure 2].
| Discussion|| |
The reconstruction of dorsal defects in the distal foot might be problematic. Many reconstruction options were described, and they have specific disadvantages.
Long-term durability is a common issue with grafts, and the defects in this area are frequently complicated by exposed tendons or bones, making skin grafts unfeasible. Usage of the local muscle flaps or free flaps may provide good coverage, but mostly they are too bulky. This causes functional problems with shoe wear. Free flaps are associated with technical difficulties and less than optimum cosmetic and functional outcomes.
Although dorsal pedal flaps might be used on a distal basis, there is a substantial risk of donor site sequela., Instead, the first dorsal metatarsal artery perforator flap (FDMtAP) is a preferable choice, especially to reduce donor site healing difficulties. FDMtAP flap restores soft tissue without dissecting the pedicle. This minimizes donor site morbidity and surgery time by avoiding intramuscular dissection. An adipofascial version of FDMtAP, rather than the fasciocutaneous form, may also produce a larger-sized flap, a larger rotation arc, and largely avoid donor site morbidity, but needs skin graft at the recipient site. Raising this adipofascial flap based on the perforator may allow the flap to be used to cover more distal defects and to gain a more stable blood supply.
The first dorsal metatarsal artery adipofascial perforator flap appears to be a safe, rapid, and simple procedure for reconstructing the dorsum of the distal foot and great toe defects, as it provides optimal functional and esthetic outcomes with minimal donor site morbidity.
