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.

Provided herein are methods and systems for the compression and/or distraction of a bone fracture. The system includes a rod configured to be at least partially inserted into the bone and a body defining a bore configured to circumscribe a portion of the rod. The system further includes a device with a first member and a second member joined at a fulcrum. The first member includes a channel for receiving a portion of the rod. The bone fracture compression or distraction includes inserting the rod into the bone, placing the first member of the device over the rod, positioning the second member of the device into a feature of a bone plate, and moving the first member and the second member toward each other.

A system includes a cutting guide having a base body configured to be fixed to a first bone of a patient and a cutting slot block configured to provide a guide for cutting at least one of the first bone and a second bone of the patient. The cutting slot block is rotationally coupled to the base body. The cutting slot block is configured to rotate in a first rotational direction. The cutting guide comprises a distal portion and a proximal portion.

The present disclosure provides for an interlocking cannula system that includes a handle and a set of cannulas. The set of cannulas includes a sequence of smaller to larger cannulas constructed such that the smaller cannulas may be nested within larger cannulas. Each cannula in the set of cannulas includes a respective locking mechanism configured such that each cannula may be interlocked with each of the other cannulas in the set. The handle is constructed such that each cannula in the set may interlock with the handle by the respective locking mechanism of the cannula. In some instances, the respective locking mechanisms are constructed to enable an ordered release of the cannulas.

Devices and methods for stabilizing bone. The devices and methods may provide a more balanced proximal and distal compression when stabilizing bone. An exemplary device may comprise a staple member including a bridge connecting a first leg to a second leg. The device also may comprise a resilient arm elongated between a fixed end and a free end, and projecting from the first leg and/or from an end region of the bridge adjoining the first leg. At least a portion of the resilient arm intermediate the fixed and free ends may be inwardly adjacent and spaced from an upper region of the first leg.

The present application provides new and innovative anterior clavicle plates and systems for clavicle fracture fixation. The provided anterior clavicle plate is shaped to better conform to or fit the anterior and lateral surfaces of a patient's clavicle as compared to typical anterior clavicle plates. This improved conformance can help reduce the incidence of tissue irritation, which reduces the chances of a second surgery being needed for removal of the anterior clavicle plate. The improved conformance can also result in an anatomically better fracture reduction than typical anterior clavicle plates and an increased fixation strength. Additionally, an instrument provided by the present application can help a surgeon install the provided anterior clavicle plate more quickly and with increased flexibility and consistency than typical systems.

A new and innovative medical sizing instrument and method are provided for determining an appropriate depth and/or length of a clavicle hook plate for a patient. The provided medical sizing instrument may enable a surgeon to determine an appropriate hook depth without having to switch between different components, such as a series of templates. In an example, a surgeon may insert the medical sizing instrument into a patient the same as the surgeon would a clavicle hook plate, adjust the hook depth on the medical sizing instrument until a hook depth is obtained that appropriately maintains the anatomical alignment of the patient's clavicle and acromion, and read an indicated depth on the medical sizing instrument. The surgeon may then remove the medical sizing instrument from the patient and select the appropriate clavicle hook plate to insert into the patient.

A method of manufacturing an apparatus for fixing bone includes mating a first plate with a second plate, where the first plate includes a screw slot and the second plate includes a through hole corresponding to the screw slot; and placing a screw body into the screw slot and the through hole. The screw body includes a screw portion and an insertion portion. The screw body is placed into the screw slot using the insertion portion of the screw body. The method further includes removing the insertion portion of the screw body. The screw portion remains within the screw slot and the through hole after the insertion portion is removed.

A bone screw is provided with a resilient component that enables a surgeon to measure the amount of compression effected by the bone screw during installation and dynamically maintain that compression across the provided bone screw during fracture healing. The provided bone screw includes a leading component, a trailing component, and a resilient component that may be compressed between the leading and trailing components and which is arranged such that the bone screw's axial rigidity is maintained. The leading and trailing components may be engaged together or independently by a driving instrument. Advancing or receding only the leading component or only the trailing component alters a compression force effected by the bone screw between two bone fragments, enabling a surgeon to set a desired compression force. A measurement tool is also provided that may be used to measure an amount of compression force effected by an installed bone screw.

An anchor device for attaching suture material to bone includes a body portion having a first end and a second end. The body portion includes a trabecular mesh core that at least partially defines a central bore between the first end and the second end. The trabecular mesh core includes a plurality of openings configured to receive/allow/facilitate bone growth through the trabecular mesh core. The body portion also includes at least one thread extending spirally along an exterior of the trabecular mesh core. The anchor device further includes a post at least partially positioned within the central bore and rotatably coupled to the body portion, wherein the post comprises a fork extending from the second end of the body portion and configured to attach soft tissue to the bone using the suture material. The body portion and the post are additively manufactured from a biocompatible material.
