Definition: The word 'adenemphraxis' means "tumor of the epiphysis (endosteal) of the humerus" in Greek. It refers to an abnormal bone growth that can lead to increased pain, swelling, and deformity. In medical terms, it is a type of osteochondral disorder characterized by the abnormal development of the epiphyseal cartilage around the endosteum (bone outer layer), which may result in changes in the length or shape of the arm bone. This condition can cause severe pain and discomfort as well as deformity and loss of function. Treatment options for adenemphraxis include surgery to remove abnormal growths, bone grafting to replace lost cartilage, and radiation therapy if necessary. It's important to consult with a healthcare professional who specializes in orthopedic care to determine the best course of treatment based on your specific medical history and condition.
