Callus Under The Big Toe
Calluses and corns can cause significant pain resulting in activity limitation. Uneven pressure due to abnormal foot structure and Biomechanics is one of the most common reasons for such calluses and corns.
Here is a case of a patient with long term callus under the big toe which has been treated by serial debridements in office by a physician over the years. After getting initial X-Rays, I noticed an extra piece of bone under one of the joints of the big toe, the Interphalangeal joint. This is an accessory bone which can become symptomatic is some patients. Since the patient had been suffering from this condition for all of adult life, this required surgical excision.
As you can see in the picture below, this is about 1.5 cm in size. This may not seem large but in the foot, there isn’t much real state so in the foot a 1.5 cm sized extra bone can cause many issues.
