Abstract: A nail for compressing two bone parts to treat bone fractures or osteotomies is provided. The nail has an elongate smooth portion and an elongate threaded portion that is constructed for generating axial compression along a length of the elongate threaded portion between two bone parts. The nail may also have one or more apertures for installing one or more crossing screws through the nail. An installation instrument particularly constructed to install the provided nail is provided. A first and second portion of the provided nail installation instrument may rotate relative to one another when a locking mechanism is disengaged, but are locked in position relative to one another when the locking mechanism is engaged, which enables installation of the provided nail.

Abstract: A drill component is provided that enables determining the drill component's insertion depth into bone via direct measurements. The direct measurements help provide more consistently accurate insertion depth measurements as compared to typical insertion depth measurement methods that indirectly determine insertion depth using cannulas outside of the bone. The determined insertion depth corresponds to an implant size or length that a surgeon should select for a procedure. The drill component includes a shaft having an insertion end that includes multiple indications or markings that are visible on radiographic or fluoroscopic images. From one or more captured radiographic or fluoroscopic images of the drill component advanced into bone, a surgeon may count a quantity of indications or markings of the drill component on the one or more radiographic or fluoroscopic images to determine the drill component's insertion depth into the bone.

Abstract: A system for implant delivery includes an 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.

Abstract: A cannulated headless compression screw is provided with an attachment mechanism that enables coupling various attachments to the headless compression screw. The headless compression screw includes a screw thread on its exterior that is adapted to effect compression between two bone fragments. For instance, the exterior screw thread may have a variable pitch formed to effect such compression. The interior of the headless compression screw's trailing end includes an interface that is adapted to engage with a driving instrument. A surgeon may drive the headless compression screw into bone via the driving instrument and then access the attachment mechanism to couple an attachment to the headless compression screw.

Abstract: Systems and methods for fixing bone using an intramedullary nail locked to an encircling anchor including a bushing and a locking member. An exemplary system may include any combination of the nail, one or more bushings, one or more locking members, an instrument to guide installation of the bushing, at least one drill, and a driver that attaches to the bushing. The instrument may define a guide axis and be configured to be coupled to a bone such that the guide axis extends across the bone. The instrument may be used to guide a drill, the bushing, and/or the locking member along the guide axis into the bone. The nail may be configured to be placed along the medullary canal of the bone such that the nail extends through the bushing, and the locking member may be configured to lock the nail to the bushing.

Abstract: The present disclosure provides medical instruments and medical instrument components having targeted torsional failure. Such targeted torsional failure helps prevent a surgeon from applying excessive torque that may damage an implant or bone, and also helps avoid the problems and complications that arise when medical instruments break within patients during surgical procedures. To provide such targeted torsional failure, the disclosed medical instrument components include a breakaway section designed so that the component breaks at a desired amount of torque, at a desired location, and in a desired way. The provided medical instrument components may also include a sleeve to increase side-loading strength that may otherwise be reduced due to the breakaway section. The increased side-loading strength may help prevent accidental bending-type failures. The presently disclosed medical instrument component therefore provides targeted torsional failure without sacrificing side-loading strength.
