Background: The pathogenesis of hereditary multiple exostoses is mainly related to genetic variants and often requires surgical resection when it causes clinical symptoms. This case report describes a variant in the EXT1 gene and the management of postoperative femoral artery rupture. Case Presentation: We present a case of a 11-year-old boy, who developed hereditary multiple exostoses. The patient presented with multiple bone swellings throughout the body and difficulty squatting on the right thigh. Genetic testing showed that the child had a heterozygous variant in the EXT1 gene c.1722+1G>A (p.?). We performed resection of osteochondroma of the right femur but after surgery there was persistent bleeding from the wound. Surgical exploration revealed a rupture of the right femoral artery, which we repaired. Conclusions: The diagnosis of hereditary multiple exostoses relies on clinical examination and genetic testing. Surgical resection is indicated for symptomatic cases with functional impairment. To prevent vascular injuries such as femoral artery rupture, meticulous surgical technique is essential, including thorough smoothing of the resected bone surface and careful intraoperative assessment of adjacent neurovascular structures. In cases of postoperative bleeding or suspected pseudoaneurysm, prompt imaging and surgical exploration are critical for timely vascular repair.
