Abstract
Chondroblastoma of the femoral head is a benign tumor originating from immature chondrocytes (chondroblasts), also known as Codman's tumor. This tumor is mainly located in the epiphysis of the end of long bones, especially in the region of the femoral head. It is more common in children and adolescents. Its etiology is derived from embryonic cartilage, or mutations in chondroblasts. The diagnosis mainly depends on imaging examination and histopathological examination. Surgical resection is the main treatment method, and there are also many new methods such as gene therapy and immunotherapy. This article reviews the etiology, diagnosis and treatment of chondroblastoma of the femoral head, so as to provide ideas and basis for further clinical research on adolescent chondroblastoma of the femoral head.
