Metatarsus adductus is a condition where the rear foot is normal but the midfoot deviates medially (inwardly). It is a common foot deformity, occurring in one to two cases per 1,000 births. Of MTA cases identified at birth, 85 to 90 percent resolve by one year of age. Another study found that 87 percent of MTA cases had resolved by six years of age, with only about 4 percent remaining at age 16.
Mild MTA will resolve on its own. Moderate (semi-flexible, reducible) MTA can be treated with stretching exercises. For the majority of MTA cases, the prognosis is good. In severe cases, excessive compensation at the level of the mediotarsal joint can lead to the development of bunions, hammertoes, and other disorders. Serial casting and bracing address these issues.
Other names or similar foot conditions:
- Metatarsus varus
Symptoms:
- None in children but if the condition does not correct itself bunions, hammertoes and other toe disorders can develop
- Pain across the lateral (outside) portion of the forefoot
Signs to look for:
- Subluxation of the forefoot at the tarsometatarsal joints (the joint area is loose and moves)
- This is an observable condition
Possible Causes:
- Intra-uterine positioning
Goals:
- This can usually be corrected as an infant
- When not corrected as an infant, goals include:
- Move foot forward with as little lateral movement as possible
- Right kind of shoes for this type of foot
- Take pressure off the front part of the foot
- Restore a normal gait
How We Help:
Arch Supports:
- BioOrthotics exercising support with metatarsal lift
- Lower and thinner arch support with longitudinal and metatarsal support for use when shoes cannot accommodate the BioOrthotics exercising support
Shoes:
- Extra depth, double or triple depth shoe with high toe box, firm heel counter, rocker sole and connecting shank
- For Smart footwear, wear stable heel to toe rockers or shoes or shoes with titanium springs
- Avoid flip-flops. Only wear sandals with a back and only the Orthaheel, Alegria or Aetrex brand
- Wear heels and pumps only as long as absolutely necessary
- Avoid going barefoot or do so on a minimal basis only
Activities:
- Regular stretching of gastrocnemius and soleus muscles, Achilles tendon and arch structure
- Rotate weight bearing exercises, such as walking or jogging, with non-weight bearing exercising, such as swimming or bicycling
