Bone thickening
Introduction
Introduction Bone thickening refers to the formation of new bone by osteoblasts differentiated from the deep outer layer of the epithelium to thicken and thicken the bone. Mesenchymal cells directly differentiate into osteoblasts, which are directly ossified by the connective tissue membrane containing osteoblasts. Mainly relying on intramembranous osteogenesis, the bone cells in the inner surface of the bone marrow cavity continuously destroy and absorb the bone mass, so that the bone marrow cavity is enlarged; the bone cells in the deep outer layer of the epithelium continuously make the bone mass to thicken the bone to thicken the bone. Bone thickening has normal bone thickening and pathological bone thickening. Normal bone thickening is based on the physiological characteristics of the human body and the functional function of the bone is more regularly thickened as the person's age increases. Pathological bone thickening needs to be diagnosed according to the specific disease.

Diagnosis
Differential diagnosis
Hemangioma: Soft tissue hemangioma can be associated with marked thickening and sclerosis of the cortex, and circular calcification can be seen in the soft tissue.
Pulmonary osteoarthrosis: thickening of the maxillary cortex of tubular periosteal hyperplasia, osteosclerosis of the carpal and humeral cortex.
Wax-like bone disease: trabecular bone is infiltrated by fibrous tissue, bone marrow is replaced by fibrous tissue, thickened cortical bone, periosteal hyperplasia and sclerosis. The disease occurs mostly on one side of the long tubular bone and the short tubular bone, and is injected as a wax oil.
