the Bump on the Outer Midfoot: Is It Normal? - Orthopedics

Share to:

The bones in the middle part of the outer side of the foot are protruding?


It seems to be the fifth metatarsal, and both feet are noticeably protruding.
There have been no fractures, and it has been this way since childhood.
Is this normal? There is no pain or discomfort, but it is not aesthetically pleasing.
Is there a way to make it flatter?

The base of the fifth metatarsal in the foot may typically protrude slightly, which can be a normal congenital variation.
If you feel there is an issue, you can get an X-ray to check for any problems.
If it needs to be flattened, surgery may be required, but it's important to first assess whether it is necessary.

More Info


The prominence you are noticing on the outer midfoot, particularly around the fifth metatarsal, is likely a condition known as a "bunionette" or tailor's bunion. This condition is characterized by a bony bump that forms on the outside of the foot at the base of the fifth toe. It can occur due to various factors, including genetic predisposition, foot structure, and the type of footwear worn over time.

From your description, it seems that you have had this condition since childhood, and it is asymptomatic, meaning it does not cause you any pain or discomfort. This is a positive sign, as bunionettes can sometimes lead to pain or discomfort, especially if they rub against shoes. The fact that you have not experienced any fractures or injuries in that area further suggests that this is a benign anatomical variation rather than a pathological condition.

In terms of whether this is "normal," it is essential to understand that foot anatomy can vary significantly from person to person. Some individuals may have more pronounced bony structures due to their genetic makeup or the way they walk (gait). If the bump does not cause any pain or functional issues, it is generally considered normal for you.

Regarding the aesthetic concern and whether it can be made "flatter," there are a few options to consider:
1. Footwear Choices: Wearing shoes that provide adequate space for your toes can help minimize the prominence of the bump. Avoiding tight or narrow shoes can prevent irritation and may help you feel more comfortable.

2. Orthotics: Custom orthotic devices can be designed to redistribute pressure on your foot and potentially improve the alignment of your toes. This may not flatten the bump but can enhance comfort and reduce any potential future issues.

3. Surgical Options: If the prominence becomes painful or if you desire a cosmetic change, surgical options are available. Procedures can involve removing the bony prominence or realigning the toe. However, surgery is typically considered only when the condition causes significant discomfort or functional impairment.

4. Physical Therapy: Engaging in physical therapy may help strengthen the muscles around your foot and improve overall foot mechanics. This can sometimes alleviate discomfort and improve foot function.

5. Monitoring: Since you have had this condition for a long time without issues, regular monitoring may be all that is necessary. If you notice any changes, such as increased pain or difficulty walking, it would be wise to consult a healthcare professional.

In conclusion, the bump on your outer midfoot appears to be a benign anatomical variation, especially since it has been present since childhood without causing pain. While there are options to address aesthetic concerns, it is essential to prioritize comfort and function. If you have further concerns or if the condition changes, consulting with a podiatrist or orthopedic specialist would be beneficial for personalized advice and treatment options.
