OBJECTIVE: A very few flaps would be described as versatile as the Keystone Flap. There is an increasing demand for coverage of defects in lower limb due to traumatic defects as well as other parts of the body. Keystone flap is one of its kind, which is simple and easy to perform. It is a safe option for conditions where microsurgery may not be a viable option. The relative simplicity of this flap makes it a to go option at many places. METHODS: A prospective study was developed from October 2017 to December 2019 at SMS Hospital, Jaipur. We assessed the size of the flap, operation time, average hospital stay and the complications. Perforators over the leg were Doppler marked preoperatively over which the flap was raised. RESULTS: 50 patients were taken into the study. 30 key stone flaps were done to cover lower limb defects, 10 flaps were done for upper limb defects and the remaining 10 were for trunk defects. The average intraoperative time from skin incision to final suture was 50 min (range 20-90 min). The largest defect covered by keystone flap in our series measured 50 × 20 cm and the smallest defect covered was 8 × 4 cm. The average hospital stay was 3 days. We observed partial flap necrosis in 2 cases which required skin grafting. 3 other cases had wound infection leading to wound dehiscence, which required secondary suturing. The overall success rate was 95%. CONCLUSION: The Keystone flap being a versatile flap with its qualities of replacing "like with like", easy to perform, use of local tissue, good vascularity and a low complication rate makes it an excellent flap for a variety of defects. The KeyStone flap allows reconstruction in a single stage and is a relatively easy and fast technique for the beginner as well as the experienced surgeon. We believe it should be incorporated more into a surgeons practice.
