A sacroiliac joint implant system includes a primary implant configured to be received in a sacroiliac joint of a patient and a secondary implant configured to couple with the primary implant. The primary implant includes a body extending from a proximal end to a distal end and a plurality of threads extending from the body. The secondary implant includes a first anchor configured to anchor within a sacrum of the patient and a second anchor configured to anchor within an ilium of the patient.

A system, method, and computer program product for allowing any surgeon, including those surgeons who perform a fewer number of a replacement procedure as compared to a more experienced surgeon who performs a greater number of procedures, to provide an improved likelihood of a favorable outcome approaching, if not exceeding, a likelihood of a favorable outcome as performed by a very experienced surgeon with the replacement procedure, such as by understanding the prosthesis installation environment (e.g., cup/cavity interface) and to provide intelligent and interactive tools and methods to standardize the installation process and provide feedback regarding a quality of insertion/installation. Force sensing is included to aid in quantifying installation of an implant, particularly a cup into a pelvic bone.

A system and method for improving upon an ability of a surgeon to repair traumatic bone injury using new materials, components, and structures. A structure may be used as an implant or a component of an external fixator for a fractured long bone with that structure having anisotropic and viscoelastic properties, such as through additive manufacturing techniques.

A tensioner tool for assessing joint laxity is disclosed. The tensioner tool comprises a pair of pivotally coupled arms, each arm comprising a proximal handle portion, a distal portion, and an insertion tip selectively coupled to the distal portion. The pair of arms pivot between a compressed configuration for insertion within the joint and an expanded configuration for distraction of the joint by applying a force to the handles, thus spreading the insertion tips. The tensioner tool also comprises a force sensor configured to measure the force applied to the handle portion and a positional sensor configured to measure a separation distance between the pair of arms. The tensioner tool also comprises a processor configured to calculate a distraction force at the insertion tips based on the measured force and to calculate a tip distance between the insertion tips based on the measured separation distance.

A glenosphere handling tool, which can be an impactor, is provided that includes an elongate body and a retention portion. The retention portion is disposed at a distal end of the elongate body. The retention portion includes a plurality of wall segments of the elongate body separated from each other by one or more slots. The slot(s) extends proximally from the distal end of the elongate body. The retention portion also includes an enlarged periphery at the distal end of the elongate body. The enlarged periphery comprising a proximally facing edge configured to engage an inner wall surface of a glenosphere. The retention portion is configured such that when the retention portion is in a free state the proximally facing edge faces and may contact a surface of a glenosphere to retain the glenosphere. The retention portion is configured to be deflected at the distal end of the elongate body such that the enlarged periphery has a reduced profile for separating the handling tool from a glenosphere.

Systems, methods, and devices are disclosed for navigational arrays for attaching to surgical tools, the arrays comprising a frame comprising fiducials for detection by an optical navigation system, and a body having a first end for supporting the frame and a second end defining an opening, wherein the opening is aligned with a first axis of the surgical tool, wherein the opening engages a stationary surface adjacent to the surgical tool, and wherein the opening engages features disposed at predetermined even intervals on the stationary surface adapted to allow repositioning of the array from a first position to a second position, wherein the second position is at least one of a rotational offset or an axial offset from the first position. The stationary surface may be a step disposed on an adapter inserted into the surgical tool. The stationary surface may be a sheath covering a rotatable shaft inserted into the surgical tool. The stationary surface may be a sleeve disposed on the surgical tool. The arrays may be part of a computer-assisted surgical system.

Surgical instruments, systems and methods are described for selecting a size and cutting bone for inserting of an intervertebral disc prosthesis. The surgical instrument includes a combined intervertebral disc prosthesis sizing trial and a slot or channel cutter which is movable with respect to the sizing trial.

An apparatus for implanting a medical implant into bone includes: an implant having at least one predetermined natural frequency; and an instrument, comprising: a housing; a coupler carried by the housing and configured to be mechanically connected to a medical implant; and a forcing mechanism carried by the housing and operable to apply a cyclic excitation force at the predetermined natural frequency.

Systems and methods for providing alignment of instruments and/or prostheses in various surgical operations are provided herein. The systems and methods generally include one or more sensors coupled to a patient's bones or other surgical tools, the sensors can detect their position and orientation in space and communicate this information to a processor. The processor can utilize the information to display data to a surgeon or other user regarding the position, angle, and alignment of a patient's bones, surgical tools, and prostheses. Further, the one or more sensors can be aligned to the patient's anatomy using a patient-specific alignment guide that interfaces with a portion of the patient's anatomy in a single position/orientation.

Technologies for monitoring impaction and predicting impaction state during an orthopaedic surgical procedure include one or more impaction sensors that generate sensor data. The surgical procedure includes impaction of an orthopaedic implement such as a surgical instrument or a prosthetic component. An impaction analyzer generates an impaction state prediction with a machine learning model based on the sensor data. The impaction state prediction may include an unseated state, a seated state, and a fracture state. An impaction state user interface outputs the impaction state prediction. A model trainer may train the machine learning model with labeled sensor data.
