VERTEBRAL ENDPLATE SHAVER WITH HEIGHT ADJUSTABLE BLADES
20230157711 · 2023-05-25 · ·

A vertebral endplate preparation (decorticating) tool has height adjustable blades at a distal end of a shaft assembly for decorticating/shaving vertebral endplate material from spinal vertebrae, translates axial movement of a control rod of the shaft assembly of the vertebral endplate preparation tool with height adjustable blades into radial blade height change (extension and retraction) through a controller of a handle assembly. The blades may also be configured for collecting and removing shaved vertebral endplate material. The blades controllably move outward radially from the distal end of the shaft assembly and controllably move inward radially into the distal end of the shaft assembly upon manipulation of the controller. Radial blade extension and retraction from the distal end may be accomplished via mutual angled dovetail features of the blades and the distal end, or via pins of the distal end of the shaft assembly situated in angled slots of the blades.

BONE MATERIAL HYDRATION DEVICES AND METHODS

A device for hydrating particulate bone material is provided. The device comprises a tubular member having an interior surface and an exterior surface. The interior surface is configured to receive the particulate bone material and a hydration fluid. The exterior surface has a plurality of pores configured to allow the hydration fluid to flow into the interior surface of the tubular member and hydrate the particulate bone material. The plurality of pores are smaller in size than the particulate bone material. Methods of dispensing particulate the bone material are also provided.

Surgical systems and methods for assembling and fusing bones
11653936 · 2023-05-23 · ·

A surgical system for use in correcting hammer toe or otherwise straightening toes or fusing other bones to one another includes a male drill bit and a female drill bit, as well as an absorbable pin. The male and female drill bits are configured to define complementary features from opposed, or facing, ends of bones that are to be fused to one another. The male and female drill bits may also be configured to define channels through the lengths of the bones that are to be fused to one another, with the channels being configured to align and define a continuous channel through the bones when they are assembled. The absorbable pin, which may be absorbed by a subject's body over time, is configured to be positioned in the continuous channel, and may hold the bones in an assembled relationship before and while they fuse to one another.

The surgical instrument may include: an elongated body having a distal end; a housing disposed at least partially within the elongated body and pivotably coupled to the elongated body; and an actuator engaged with a proximal end of the elongated body and operably associated with the housing such that the housing pivots about a pivot point upon actuation of the actuator. In another embodiment, the surgical instrument may include: an elongated body having a segmented distal tip; a guide barrel extending longitudinally within the elongated body, the guide barrel being substantially aligned with a bore within the segmented distal tip, wherein the segmented distal tip is configured to transition between an unexpanded configuration and an expanded configuration.

COMBINATION DRILL GUIDE AND DEPTH GAUGE SURGICAL INSTRUMENT FOR IMPLANTING AN ACETABULAR CUP COMPONENT AND ASSOCIATED SURGICAL METHOD

A combination drill guide and depth gauge surgical instrument for use during a surgical procedure to implant an acetabular cup component into a surgically-prepared acetabulum of a patient's hip includes an elongated shaft having a drill guide on an end thereof. The instrument also includes a retractable depth probe that may be used to gauge the depth of the holes drilled by use of the drill guide. A method of using such an instrument is also disclosed.

Systems and methods for pre-operative visualization of a joint
11464569 · 2022-10-11 · ·

A method for visualizing at least one region of a joint that deviates from a baseline anatomy includes receiving image data associated with a joint of a subject, generating a three-dimensional model of at least a portion of the joint using the image data, identifying at least one region of the joint that deviates from the baseline anatomy by comparing the three-dimensional model to a baseline model, generating a measurement of a characteristic of the joint at one or more predefined locations using the three-dimensional model and a coordinate system, and generating a three-dimensional rendering of the model that includes a visual indication of the at least one region of the three-dimensional model that deviates from the baseline so that the region is visually indicated according to degree of deviation, and a representation of the measurement of the characteristic of the joint that is positioned according to the predefined locations.

ACROMIOCLAVICULAR HOOK PLATE

A bone plate for treating acromioclavicular dislocations includes a shaft including a lateral portion sized and shaped to be positioned along a superior aspect of a lateral clavicle, the shaft including a plurality of openings extending therethrough for receiving bone fixation elements therein and a hook member extending from the shaft so that, in an operative position, the hook member is hooked under an acromion and the lateral portion of the shaft is positioned on the superior aspect of the lateral clavicle, the lateral portion of the shaft being substantially rounded so that the hook member is movable in one of an anterior direction and a posterior direction while the shaft maintains contact with the superior aspect of the lateral clavicle without any portion of the lateral portion of the shaft protruding beyond a surface of the lateral clavicle.
