摘要： A compression nut for treating a bone includes a head and a body extending longitudinally from the head to a free end. The body includes an exterior threading along an exterior surface of a threaded portion of the body separated from the head via an unthreaded portion. The nut also includes a channel extending longitudinally through the body. The channel includes an interior threaded extending along an interior surface of the channel configured to threadedly engage an end of a locking screw received therein.

摘要： A screwdriver assembly includes a screwdriver shaft and an insert. The screwdriver shaft extends longitudinally from a proximal end to a distal end and having a longitudinal channel extending therethrough. The insert has a longitudinal shaft received within the longitudinal channel and a distal end extending distally relative to the distal end of the screwdriver shaft. The insert shaft is rotatable relative to the screwdriver shaft. The distal end of the insert is sized and shaped to engage a head of a screw. The distal end of the insert is disengaged from the screw head by rotating the insert relative to the screwdriver shaft.

摘要： A bone screw removal device includes a shaft extending longitudinally from a proximal end to a distal removal tip. The removal tip includes a first portion at a distal-most end of the removal tip, a second portion extending proximally from the first portion and a third portion extending proximally from the second portion. The first portion is sized and shaped to be received within a retaining recess of a bone screw to clear away tissue growth as the first portion is inserted through a driving recess of a bone screw and into the retaining recess. The second portion is configured to be received within a driving recess. The third portion is configured to clear away tissue growth over a proximal end of the bone screw as the first and second portions are inserted into the retaining recess and the driving recess, respectively.

摘要： A modular system for treating a bone includes a main body including a channel extending therethrough. A distal end includes a driving feature sized and shaped to engage a corresponding driving structure of one of first and second bone screws. The system also includes an inner shaft sized and shaped to be inserted into the channel and including a distal end including a retaining feature for engaging a corresponding retaining structure extending within a recess at a proximal end of the first screw. Furthermore, the system includes an outer shaft extending longitudinally and including a channel extending therethrough. The channel of the outer shaft is sized and shaped to slidably receive the main body therein and including a retaining feature extending along a distal end thereof. The retaining feature of the outer shaft engages a retaining structure extending along an exterior surface of the second screw.

摘要： A storage system, including: a lid; a bottom side of the storage system opposite the lid; a first plurality of medical implants stored in a rack, wherein first plurality of medical implants are oriented in a first direction from the lid to the bottom side; a first drawer located between a portion of the first plurality of medical implants and the bottom side of the storage system; a second plurality of medical implants stored in the first drawer, wherein the second plurality of medical implants are oriented in a second direction that is substantially perpendicular to the first direction; and a drawer locking mechanism configured to engage the first drawer when the lid is closed to prevent the first drawer from sliding out of the storage system and to disengage the first drawer when the lid is open to allow the first drawer to slide out of the storage system.
