US 2025/0017604 A1 · OSTEOTOMY SYSTEMS AND TECHNIQUES FOR TREATING METATARSAL MISALIGNMENT

Abstract

Systems, devices, and techniques can be used to perform an osteotomy on a bone of a foot, to realign a cut bone portion relative to an adjacent bone portion, and/or to fixate a moved position of the cut bone portion relative to the adjacent bone portion for fusion. In some examples, the disclosed devices and techniques can be used as part of a metatarsal correction procedure in which a metatarsal is treated to correct a bunion deformity.

Dependent claims

An intramedullary implant insertion and positioning instrument, the instrument comprising:

a body configured to releasably connect to an intramedullary implant having a stem portion insertable into a first metatarsal portion and a plate portion positionable against a second metatarsal portion;
and
a bone positioning device operatively connected to the body, the bone positioning device being configured to apply a force between the body and a bone portion underlying the body.

A method comprising:

cutting a metatarsal bone of a foot into a first metatarsal portion and a second metatarsal portion;
inserting a stem portion of an intramedullary implant into the first metatarsal portion and positioning a fixation aperture extending through a plate portion of the intramedullary implant overlying the second metatarsal portion;
using a bone positioning device releasably connected to the intramedullary implant to move the second metatarsal portion relative to the first metatarsal portion in at least one plane;
and
inserting a fixation member through the fixation aperture extending through the plate portion of the intramedullary implant and into the second metatarsal portion to fixate a moved position of the second metatarsal portion relative to the first metatarsal portion.
