Examples of periosteal reactive bone in selected specimens of Triceratops. A periosteal reaction can result from a large number of causes, including injury and chronic irritation due to a medical condition such as hypertrophic osteopathy, bone healing in response to fracture, chronic stress injuries, subperiosteal hematomas, osteomyelitis, and cancer of the bone.
Acute periostitis is due to infection, characterized by diffuse formation of pus, severe pain, and constitutional symptoms, and usually results in necrosis.It can be caused by excessive physical activity as well, as in the case of medial tibial stress syndrome (also referred to as tibial periostalgia, soleus periostalgia, or shin splints).
It is called onion skin periosteal reaction because it resembles the layers of an onion. These layers are formed due to any pathological process that leads to the variable, excessive growth of the bone. [1] Onion skin periosteal reaction is seen in osteosarcoma, [2] Ewing sarcoma and Langerhans cell histiocytosis. [3]

It contains codes for diseases, signs and symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or diseases. [1]
Hypertrophic osteoarthropathy is a medical condition combining clubbing and periostitis of the small hand joints, especially the distal interphalangeal joints and the metacarpophalangeal joints.
The advancing tumour displaces the periosteum away from the bone medulla. The displaced and now lateral periosteum attempts to regenerate underlying bone. This describes a periosteal reaction. [citation needed] The main causes for this sign are osteosarcoma, Ewing's sarcoma, eumycetoma, and a subperiosteal abscess. [3] [4]
The ICD-10 Clinical Modification (ICD-10-CM) is a set of diagnosis codes used in the United States of America. [1] It was developed by a component of the U.S. Department of Health and Human services, [ 2 ] as an adaption of the ICD-10 with authorization from the World Health Organization .
