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]
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.
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 proliferative reaction of bone can also create delicate laminations constituting the periosteal layers and giving the radiographic appearance of an onion peel. [10] Plain films add valuable information in the initial evaluation or screening.
The periosteal cells distal to (at the far end of) the fracture gap develop into osteoblasts, which form woven bone [citation needed] through bone resorption of calcified cartilage and recruitment of bone cells and osteoclasts. [4] The fibroblasts within the granulation tissue develop into chondroblasts which also form hyaline cartilage.
Tammy Slaton has investigated undergoing “head-to-toe” skin removal surgery. In a teaser video for season 6 of 1000-Lb. Sisters, posted via Entertainment Tonight’s YouTube page on Tuesday ...
After dermatologic surgery, the presence of suture materials at the wound site can cause redness and swelling, yet these suture reactions may not necessarily indicate allergy or infection. Other common complications include hypertrophic or keloid scars, bruises, suture marks, and skin color changes, which may be temporary or permanent.
The periosteum is a membrane that covers the outer surface of all bones, [1] except at the articular surfaces (i.e. the parts within a joint space) of long bones. (At the joints of long bones the bone's outer surface is lined with "articular cartilage", a type of hyaline cartilage.)
