Brachymetatarsia

Brachymetatarsia is characterized by an abnormally short metatarsal bone. brachymetatarsiaThe condition usually runs in certain families.  This condition usually affect the 4th metatarsal, but may affect multiple metatarsal bones.

The shortening of the bone is caused by the growth plate pre-maturely closing before growing out to full length. The cause why this happens is still mostly unknown.

  • Down’s Syndrome
  • Turner’s syndrome
  • Pseudohypoparathyroidism
  • Psuedo-pseudohypoparathyroidism
  • Albright’s syndrome

As a child, the deformity is usually asymptomatic. The primary complaint in the younger patient is often cosmetic, and many times these patients are self-conscious about their appearance. Older patients may experience symptoms of pain due to excessive pressure under adjacent metatarsal heads. Increased callus formation in the ball of the foot may be present. Skin, soft tissue, and tendon contractions lead to additional discomfort with the use of shoes.

Treatment of brachymetatarsia may include conservative care, such as an orthotic device to take pressure off the adjacent metatarsal heads. Shoe gear may be modified a possible hammertoe deformity or contracture of a toe.

Definitive treatment requires surgical correction to address the soft tissue contractions as well as the shortened metatarsal. Numerous surgical procedures exist to correct brachymetatarsia such as the following:

  • Bone Grafts
  • Metatarsal osteotomies
  • Distraction of the metatarsal with an external fixator
  • Tendon lengthening
  • Skin modifications

    Hi,

    I have the same problem in fourth metatarsal. I was curious about my condition so I googled “short toe” and found about this page and that the condition is called Brachymetatarsia. I wanna ask you something: This condition doesn’t effect me at all at the moment, neither physically, nor psychologically (I have no aesthetics concerns). So I wanna ask if it may cause any problem in the future. Like, because of the shortness of the toe, there’s a lot more pressure on the other toes than usual and it causes any damage in the bones or muscles. I mean should it be definitely treated? Or if it doesn’t bother the patient, can it be left that way? Thanks a lot.

    Regards.

    Dear Sirma,

    Sorry about the delayed response. Most of the time, this deformity is more of a cosmetic issue than an actual pain problem. If the shortened 4th metatarsal does not cause you any pain and you are not self conscious about the deformity, then I would personally leave it alone. If you happen to have pain at some point, then yes, it may have to be addressed. Thank you for your question and have a nice day.
