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.
Claims29
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
- an intramedullary insertion body configured to be inserted into a medullary canal of the first metatarsal portion, the intramedullary insertion body being operatively connected to the body, and the intramedullary insertion body and the intramedullary implant being movable relative to each other, when the intramedullary implant is releasably connected to 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 releasably connected to a body of an instrument and an intramedullary insertion body connected to the body of the instrument into a medullary canal of the first metatarsal portion;
- positioning a plate portion of the intramedullary implant overlying the second metatarsal portion;
- moving the intramedullary insertion body relative to the intramedullary implant to apply a force to the first metatarsal portion;
- and
- inserting a fixation member through a 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.
