Hip Avascular Necrosis (AVN) occurs when blood supply to the femoral head (hip ball) is disrupted, leading to bone death. AVN of the hip is most common between 30-65 yrs and it affects >30,000 people in the US each yr.
#AvascularNecrosis changes can be tracked through distinct stages seen on imaging studies (X-ray/MRI). . AVN Staging (seen on radiograph): ๐น Stage I - normal or minor osteopenia ๐น Stage II: mixed osteopenia, sclerosis and/or subchondral cysts, w/o subchondral lucency ๐น Stage III: crescent sign (linear cleft due to a subchondral fracture), early femoral head cortical collapse
#hipxray ๐น Stage IV: end-stage femoral head collapse, secondary degenerative change *Early detection is crucial! MRI can detect AVN with up to 90% accuracy even before any
#HipXray changes appear. More info on risk factors, symptoms, treatment options up soon. . Staging
#AVN Challenge X-rays (see hip x-rays in story, and YOU make the diagnosis): ๐ธ Hip A: Stage II AVN - joint space narrowing (distance between femoral head - hip socket or acetabulum), subchondral sclerosis (dense, bright white area due to bone hardening just below cartilage surface)
#hippain ๐ธ Hip B: Stage IV AVN - partial collapse (flattening) of femoral head, secondary degenerative changes including subchondral sclerosis, irregularity, osteophytes . ๐ SHARE your Hip AVN experience & insights - How easy was it to spot AVN on the x-rays?
