NettetKey features. Initial X-ray may be normal. Geographic lines. Subsidence, flattening and destruction of joint surface. Avascular necrosis ( AVN ), also known as osteonecrosis, is most common in the femoral head. In early disease the X-ray can be normal, and MRI may be required if the diagnosis is suspected clinically. NettetThe time interval between injury and the appearance of the radiographic features and the duration of radiographic signs were determined and correlated with age, sex, angulation, displacement, and location. Results: Sclerosis at the fracture margins was evident in 85% of fractures 5 weeks after injury. Widening of the fracture gap was observed ...
