Metatarsus Adductus – Adductoplasty 3D Correction

Metatarsus Adductus – Adductoplasty™ 3D Correction

The Condition

‘Metatarsus Adductus’ (MTA) deformity of the foot affects approximately 30-35% of patients with symptomatic hallux valgus; also known as bunions. This compound pathology increases the risk for deformity recurrence in 30% of cases if not managed properly from a surgical perspective. Patients that have this foot deformity are born with the problem and it does not spontaneously resolve with age or growth. The deformity becomes rigid and fixed as patients reach skeletal maturity. The long bones of the foot called the metatarsals are all deviated toward the midline of the body.

Patients with MTA appear to have severe bunions with a deviation and painful crowding of the great toe and lesser toes. Fitting shoes can also be very difficult due to a mismatch in foot width. Patients tend to have a very wide forefoot and a narrow hindfoot. The prominence of the big toe joint becomes impinged when wearing shoes. This creates a source of frequent irritation and pain that can ultimately result in nerve injury, limitation in motion, and joint arthritis.

The Treatment

The systematic approach to the surgical correction of combined hallux valgus and metatarsus adductus deformities provides the benefit of a standard reproducible surgical approach that achieves tri-planar correction at multiple joints to fully correct the compound deformity. This technique supports early weight bearing for mild, moderate and severe deformities.

This surgical technique was first described and published in the Journal of Foot and Ankle Surgery by Dr. JP McAleer and his co-authors. It makes use of specialized instrumentation he and his colleagues specifically designed to cut, manipulate and reduce the lesser tarsal metatarsal joint deformities prior to addressing the bunion via Lapiplasty® 3D Bunion Correction. This technique provides patients the benefits of a reproducible approach that facilitates the use of locking plate technology to maintain the correction at multiple levels. In our experience patients have a narrowing of the forefoot which improves foot proportions and may improve shoe wear and comfort.

JCMG Podiatry is the first facility in the State of Missouri to offer this surgical approach and its surgeons are among the most experienced in the nation. Our expert team actively educates surgeons nationally at multiple events annually on this and other techniques.
