Technologies for determining seating of an orthopaedic implant during an orthopaedic surgical procedure includes an impaction sensor and an impaction analyzer. The impaction sensor produces sensor data, in response to an impaction between an orthopaedic mallet and a surgical tool indicative of an initial impact and a secondary impact of the impaction. The impaction analyzer analyzes the sensor data to determine a temporal length between the initial and secondary impacts and determines whether the orthopaedic implant is sufficiently seated into the bone based on the temporal length,

Disclosed herein are rasp adapters, rasp systems, and method of use thereof. The rasp adapter can include a body and a retention element. The body can define a body cavity, a handle opening, and a trunnion bore. The retention element can be located within the body cavity and can include a knuckle and a heal. The knuckle can be located proximate to and movable into and out of the trunnion bore. The heal can be located proximate the handle opening. Movement of the retention element due to a force applied to the heal can cause movement of the retention element and movement of the knuckle into the trunnion bore.

Prostheses are described for stabilizing dysfunctional sacroiliac (SI) joints. The prostheses are sized and configured to be press-fit into surgically created pilot SI joint openings in dysfunctional SI joint structures. The prostheses have an integral structure with opposed elongated sections connected by a bridge section. The elongated sections, in some instances, have an unequal length.

In the context of bone surgery and in particular arthroscopic surgery, there is frequently a need for the application of “percussive force” to the distal end component(s) of a surgical device, i.e., repetitive percutient or striking force analogous to that of a hammer driving a nail. Disclosed herein are mechanisms and methods for automating and/or controlling the application of such a percussive force so as to avoid the present need in the art for a “third hand”. The present invention addresses the significant and long felt need by providing a powered percussive driver device that may be controlled directly by the primary surgeon.

A surgical implant system includes a surgical implant for securing adjacent vertebrae of a spine to each other. The surgical implant includes a spacer having at least one implant eyelet. The surgical implant system also includes at least one vertebral anchor configured for insertion through the at least one implant eyelet to fasten the surgical implant to the spine. The vertebral anchor has a tip portion, a head portion, an elongate shank extending from the head portion, and an elongate fin extending from the head portion and along a surface of the elongate shank. The elongate shank and the elongate fin form a generally t-shaped cross-section.

The present invention relates generally to implants and tools for the fixation or fusion of joints or bone segments. These tools include tissue dilators and protectors. Other tools include broaches used to shape bores in bone. The tools can also include a system for removing an implant from bone. Implants can include assemblies of one or more implant structures that make possible the achievement of diverse interventions involving the fusion and/or stabilization of lumbar and sacral vertebra in a non-invasive manner, with minimal incision, and without the necessitating the removing the intervertebral disc. Implants for fusing both sacroiliac joints of a patient include a long implant that extends across both sacroiliac joints.

An orthopedic assembly is described that comprises an orthopedic device, an anchor, and a locking mechanism. The orthopedic device can be a plate member having an aperture that is configured to receive the anchor. The anchor can include a head, neck and shank portion. The head portion can include a plurality of arms separated by grooves that are capable of splaying. The assembly is configured such that when the locking mechanism is inserted into the head portion, this causes expansion of the arms of the head. This expansion locks and secures the anchor to the orthopedic device. Various instruments are provided that can deliver the locking mechanism to the anchor, and can provide impact to lock functionality.
