Abstract Vulvar necrosis is a rare complication after lower limb fractures and hip surgeries either due to direct damage to internal pudendal artery or post-surgery ischemic necrosis due to use of a perineal post. We present a series of 3 cases post-orthopedic surgeries with vulvar necrosis. All three patients presented to us after history of orthopedic surgeries which used a perineal post intraoperatively. They developed vulvar edema and blackish discoloration 6–8 h after the orthopedic procedure and referred for further management. Traction post-related vulvar necrosis can have major psychological and functional consequences; hence, formulating measures for prevention and promptly diagnosing the condition and ensuring early management to maintain the functionality of vulva is of utmost importance.
