RESUMEN
OBJECTIVE: To report the application of medial neurocutaneous flap with perforator vessel in upper arm. METHODS: Based on the perforator vessel of medial deep main blood vessel in upper arm and blood supply of neurocutaneous flap, as well as their interrelation with vascularity of fascia skin, we designed the medial neurocutaneous flap with perforator vessel in upper arm to repair skin defects in shoulder, arm and elbow joint in 5 cases. RESULTS: All the flaps survived completely with primary healing. The patients were followed up for 6-12 months. The contour of flaps and the function of shoulder and elbow joint were satisfactory. CONCLUSION: The neurocutaneous flap has a reliable blood supply and easily performed. It is very desirable for repairing skin defect in upper extremity.
