The Indian Journal of Musculoskeletal Radiology explains that Muller-Weiss Syndrome is extremely rare and often an under-diagnosed cause of chronic foot pain. In some cases it can also cause foot deformity.
Crucially, early recognition and management of the condition can control symptoms and delay progression of the disease and secondary osteoarthritis.
The condition affects a bone in the foot known as the navicular bone, which some doctors refer to as “the keystone of the arch”. This means that the half-moon shaped bone is critical in your arch and allows your foot to move in interesting directions and ways. For tennis players, the navicular bone allows them to slide, pivot and bend.
Muller-Weiss Syndrome occurs when the outside of this bone starts to wear away or disintegrate, as a result of trauma, excessive force over time or developmental abnormality.
