Brachymetatarsia: An Overview
Brachymetatarsia is a congenital deformity (random genetic mutation) or birth defect that results in more than one metatarsal and toe being short on the same foot. There is typically a shorter toe that sits higher than the neighboring toes, situated higher on top of the foot. Of the 300 brachymetatarsia patients Dr. Lamm studied, he found the fourth toe to be the most commonly affected, with 50% of cases having the condition in both feet.

Risks of Leaving Brachymetatarsia Untreated
If left untreated, brachymetatarsia can cause excessive callouses, hammer toe, balance issues, difficulty wearing shoes, bunion deformities, and discomfort.

Brachymetatarsia FAQ
Brachymetatarsia is a random genetic mutation, without a hereditary component known to be linked. However, in Dr. Lamm’s patients and studies, he found specific toe growth plates to be active when patients are very young, but the toe growth plate stops growing as the patient becomes an older child. Other toes continue growing, while some do not.
Brachymetatarsia has been reported as 1 in less than 1,000 to 1 in 2,500 births. 30% of Dr. Lamm’s patients have bilateral brachymetatarsia.
58% of 300 brachymetatarsal patients studied by Dr. Lamm had the condition inflicted on their fourth metatarsals (toe).
Yes, you can walk directly after brachymetatarsia surgery, but you must wear a brachymetatarsia surgical shoe. It is padded to ensure comfort.
Yes, a bunion can be present in combination with brachymetatarsia and has been seen in (41%) of patients in Dr. Lamm’s study. It is common that Dr. Lamm corrects the bunion and the brachymetatarsia together in the same surgery.
Dr. Lamm uses an external fixation device for brachymetatarsia lengthening. He does not recommend implant-only techniques for brachymetatarsia. He has treated many failed cases involving implants, which often do not provide adequate length and can lead to infection, loosening, or chronic pain.
