An orthopedic impairment is defined by the Individuals with Disabilities Education Act (IDEA) as “a severe orthopedic impairment that adversely affects a child’s educational performance.” IDEA specifies that this term “includes impairments caused by a congenital anomaly [birth defects], impairments caused by disease (e.g., poliomyelitis, bone tuberculosis), and impairments from other causes (e.g., cerebral palsy, amputations, and fractures or burns that cause contractures).”
