Periostitis Periostitis Periostitis, also known as periostalgia, is a medical condition caused by inflammation of the periosteum, a layer of connective tissue that surrounds bone. The condition is generally chronic, and is marked by tenderness and swelling of the bone and pain. Acute periostitis is due to infection, is characterized by diffuse formation of pus, severe pain, 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). Congenital infection with syphilis can also cause
Tibial plateau fracture loading or weight bearing on knee. The classically described situation in which this occurs is from a car striking a pedestrian's fixed knee ("bumper fracture"). However most of these fractures occur from motor vehicle accidents or falls. Injury can be due to a fall from height in which knee forced into valgus or varus. The tibial condyle is crushed or split by the opposing femoral condyle, which remains intact. The knee anatomy provides insight into predicting why certain fracture patterns occur more often than others. The medial plateau is larger and significantly stronger than the lateral pleateau. Also, there is
