    摘要： Systems, devices, and methods for performing Lapidus bunionectomy procedures are disclosed. An example method includes inserting a plurality of metatarsal pins into the first metatarsal at a first predetermined spacing relative to the first tarsometatarsal (TMT) joint, excising the first TMT joint by cutting the bases of the first metatarsal and the first cuneiform proximate the first TMT joint, inserting a plurality of cuneiform pins into the first cuneiform at a second predetermined spacing relative to the first TMT joint, compressing the first TMT joint using a compressor block such that a cut face of the first metatarsal contacts a cut face of the first cuneiform, and fixing the first TMT joint using a bone plate and a plurality of bone screws. At least one of the plurality of bone screws may be a cross screw extending at an angle of less than 90 degrees relative to the bone plate and may anchor the resected first TMT joint to the second metatarsal or the second cuneiform to prevent recurrence of the bunion.

    摘要： An improved surgical system and procedure for correcting a deformity between first and second bones using an alignment guide based on a correction factor. The correction factor can be based on a virtual model of the first and second bones in a deformed configuration and a corrected configuration. In the virtual corrected configuration, first and second virtual axes can be fixed in the respective first and second bones. When reverted to the virtual deformed configuration, the orientation of the first and second axes can be used to determine the correction factor. The alignment guide is used to insert one or more k-wires into each of the first and second bones in a deformed configuration. A correction guide is passed along the k-wires to rotate and/or translate the first bone relative to the second bone into the corrected configuration.

    摘要： A system for implant delivery includes a n implant and an inserter. The implant includes a body that extends between first and second ends. The implant includes retainers extending outwardly from the first and second ends. The retainers are received in corresponding jaws of the inserter. When the implant is connected to the inserter and the inserter is actuated, the implant elastically deforms.

    摘要： A surgical tool and related methods are provided for removal of a bone sliver from a resected joint. The tool can include a housing including an upper end, a lower end, and a channel extending from the upper end to the lower end. A paddle member extends from the lower end of the housing. The paddle member includes a paddle shaft and a paddle head. The surgical tool further includes an insertion member that has a handle end, an extension that extends from the handle end, and a cutting tip. The extension is translatable within the channel such that the handle end and the cutting tip can move relative to the housing between a retracted position and an advanced position.

    摘要： A minimally invasive method of correcting a bunion includes performing an osteotomy to divide the metatarsal into first and second portions, creating a pocket in the first portion implanting a nail in the pocket, securing a suture to the joint capsule, tensioning the suture to align the great toe with the metatarsal, attaching the suture to the nail, and fastening the nail to the second portion. The nail includes an anchor portion for anchoring in the first portion, a head for attachment to a second portion, a passage for attachment of the suture, a first aperture for a fastener to attach the head with the first portion, and a second aperture for a fastener to attach the head with the second portion.
