Surgical management of sarcoma has evolved from amputation to limb salvage. Nevertheless, subsequent resections in previously irradiated feet are still challenging to reconstruct. First foot ray functional reconstruction is relevant due to its function in weight‐bearing and gait. The reconstruction should include a thin, pliable and non‐shearing skin paddle with vascularized long cortical bone to mimic the first metatarsal. A clinical case of a 37‐year‐old patient with a second sarcoma recurrence of the first metatarsal is presented. The patient was irradiated before this new recurrence and had a previous reconstruction with fibula allograft, but subsequently developed a first metatarsal pseudoarthrosis. A wide resection was performed (3.5 cm bone defect) and immediate soft tissue and bone reconstruction with a chimeric SCIP flap with a 17 × 8 cm skin paddle and 3.5 × 1.5 cm iliac bone (cSCIP‐IB). At 7 months post‐operatively, the patient was able to resumed full weight‐bearing. Three years later, remains without disease progression. CSCIP‐IB is a good option for foot first ray reconstruction in irradiated beds. This flap has low donor site morbidity and a higher ossification success rate compared to bone allografts.
