Devices and techniques for treating metatarsus adductus

A method for treating metatarsus adductus comprising:

• positioning a cuneiform-side guide surface of a cutting guide over a dorsal side of an intermediate cuneiform and over a dorsal side of a lateral cuneiform;
• positioning a metatarsal-side guide surface of the cutting guide over a dorsal side of a second metatarsal opposing the intermediate cuneiform and over a dorsal side of a third metatarsal opposing the lateral cuneiform;
• using the cuneiform-side guide surface to advance a cutting tool along the cuneiform-side guide surface to remove a portion of the intermediate cuneiform and to remove a portion of the lateral cuneiform;
• using the metatarsal-side guide surface to advance the cutting tool along the metatarsal-side guide surface to remove a portion of the second metatarsal and to remove a portion of the third metatarsal;
• moving the second metatarsal and the third metatarsal in a transverse plane to close a metatarsus adductus angle;
• provisionally fixating a moved position of the second metatarsal and the third metatarsal;
• and
• permanently fixating the moved position of the second metatarsal and the third metatarsal.

A method for treating metatarsus adductus comprising:

• cutting an end of at least one of a second metatarsal and an intermediate cuneiform to create an opening between the end of the second metatarsal and the intermediate cuneiform;
• cutting an end of at least one of a third metatarsal and a lateral cuneiform to create an opening between the end of the third metatarsal and the lateral cuneiform;
• moving the second metatarsal and the third metatarsal in at least a transverse plane to close a metatarsus adductus angle by at least moving the second metatarsal and the third metatarsal together as a joined bone group with preserved ligamentous attachments between the second metatarsal and the third metatarsal;
• and
• fixating a moved position of the second metatarsal and the third metatarsal.
