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
Femoral-tibial angle "genu valgum" or "genu varum", the femoral-tibial angle is about 175 degrees. Femoral-tibial angle The femoral-tibial angle is the angle between the femur and tibia. In humans, the two femurs converge medially toward the knees, where they articulate with the proximal ends of the tibiae. The angle of convergence of the femora is a major factor in determining the femoral-tibial angle. In human females the femora converge more than in males because the pelvic bone is wider in females. In the condition "genu valgum" (knock knee) the femurs converge so much that the knees touch one another. The opposite extreme
