if the toes. It usually arises due to a muscle imbalance in the foot usually due to genetically acquired diseases like charcot marie Tooth disease or sequel
of previous bony injuries or burns. Treatment may involve changing footwear, orthotic supports, braces or surgery in advanced or progressive deformities.

of deformities by cutting of bones(osteotomies) or fusing of joints varying from case to case.
