Mueller–Weiss syndrome
Osteonecrotic disease of the foot / From Wikipedia, the free encyclopedia
Mueller–Weiss syndrome, also known as Mueller–Weiss disease, is a rare[2] idiopathic degenerative disease of the adult navicular bone characterized by progressive collapse and fragmentation, leading to mid- and hindfoot pain and deformity.[3][1] It is most commonly seen in females, ages 40–60.[4] Characteristic imaging shows lateral navicular collapse.[5] This disease had been historically considered to be a form of adult onset osteonecrosis, with blood flow cutoff to the navicular.[1][6]
