Abductory midfoot osteotomy procedure for metatarsus adductus

Area of Science:

• Orthopedic Surgery
• Pediatric Orthopedics
• Foot and Ankle Surgery

Background:

• Metatarsus adductus is a common congenital foot deformity characterized by forefoot adduction.
• Current surgical techniques may not fully address the underlying midtarsal etiology.
• A need exists for refined surgical methods to correct transverse plane deformities.

Purpose of the Study:

• To introduce and describe a new surgical technique for metatarsus adductus correction.
• To demonstrate the efficacy of an abductory osteotomy in the lesser tarsal region for transverse plane realignment.
• To present the rationale behind treating metatarsus adductus as a midtarsal deformity.

Main Methods:

• A novel abductory osteotomy in the lesser tarsal region is detailed.
• The technique involves a closing wedge osteotomy of the lateral column and an opening wedge osteotomy of the medial column.
• Correction is primarily focused on the transverse plane, with potential modifications for other deformities.

Main Results:

• The described osteotomy technique allows for direct correction of forefoot adduction in the transverse plane.
• This approach addresses the midtarsal component of metatarsus adductus.
• Case studies illustrate the application and outcomes of the surgical technique.

Conclusions:

• The described lesser tarsal abductory osteotomy is an effective technique for correcting metatarsus adductus.
• This surgical method provides a means to correct transverse plane deformities by addressing the midtarsus.
• The technique offers a valuable addition to the surgical management of pediatric foot deformities.
