Polio can cause bunions
The virus is linked to a number of complications, including bunions and hammer toe.
Bunions and hammer toe are thought to be age-related conditions, perhaps in part because people who have had the polio virus – the last natural case of which occurred in 1979 – are more likely to develop the foot deformities.
Polio, arthritis and genetics are likely the main root causes of bunions and hammer toe. However, there are a number of factors that can make the bony protrusions worse in some individuals.
Research suggests that older individuals, especially those who had polio at some point, should be cognizant of the types of shoes they wear.
"Since wearing shoes that cause the toes to be squeezed together is a common factor in bunions, it explains the high prevalence of the disorder among women," said podiatrist Kamran Jamshidinia, of the Department of Podiatry at La Peer Health Systems in California.Additionally, high-risk individuals should consider using bunion splints or orthotics before their food conditions become advanced because they are easier to treat in the early stages.
