Durlacher’s corn is a type of corn that develops on the foot, specifically on the lateral aspect of the little toe, adjacent to the nail plate. This condition is named after Lewis Durlacher, a British chiropodist who first described it in the 19th century. Durlacher’s corn is also known as Lister’s corn in North America ¹ ².
Causes of Durlacher’s Corn
The primary cause of Durlacher’s corn is excessive pressure on the skin of the little toe, which leads to the formation of a thickened area of skin. This pressure can be due to various factors, including ³ ²:
- Digital deformity: A deformity of the toe, such as a rotation or clawing, can cause increased pressure on the skin, leading to the formation of a corn.
- Poorly fitting shoes: Shoes that are too tight or don’t fit properly can cause friction and pressure on the skin, leading to corn formation.
- Enlarged bone tissue: An enlarged bone tissue in the fifth toe can cause increased pressure on the skin, leading to corn formation.
Symptoms of Durlacher’s Corn
The symptoms of Durlacher’s corn can vary, but common symptoms include ⁴:
- Pain: Durlacher’s corn can be painful, especially when pressure is applied.
- Discomfort: The corn can cause discomfort and stiffness in the affected toe.
- Difficulty distinguishing from nail tissue: Durlacher’s corn can be difficult to distinguish from nail tissue, which can make diagnosis challenging.
Treatment Options
Treatment for Durlacher’s corn typically involves addressing the underlying causes of the condition. This can include ² ⁴:
- Removing the painful corn: A podiatrist can remove the corn to provide instant relief.
- Digital offloading: Offloading the toe can help reduce pressure on the affected area.
- Surgical removal: In some cases, surgical removal of the corn or the enlarged bone tissue may be necessary.
- Proper footwear: Wearing properly fitting shoes can help reduce pressure on the affected area.
Controversy Surrounding Durlacher’s Corn
There is some controversy surrounding Durlacher’s corn, with some experts believing that it may not be a corn at all, but rather an ectopic nail or a double nail of the fifth toe. Some studies have suggested that the lesions thought to be Durlacher’s corns may actually be miniature nail sections on the lateral edge of the toe ⁵.
Conclusion
Durlacher’s corn is a type of corn that develops on the foot, specifically on the lateral aspect of the little toe. While the exact cause of Durlacher’s corn is still debated, it is clear that excessive pressure on the skin is a contributing factor. Treatment options vary, but addressing the underlying causes of the condition is crucial to preventing recurrence. By understanding the causes, symptoms, and treatment options for Durlacher’s corn, individuals can take steps to prevent and manage this condition.
