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.

Bone harvesting tools and methods of use thereof are disclosed. In an embodiment, the tool comprises a chamber having a first aperture, a second aperture, an internal cavity, and a suction source fluidly connected with the chamber. The suction source is effective to generate negative pressure within the internal cavity of the chamber. The tool also has a reamer having a reaming portion, the reamer being sized to extend through the first and second apertures of the chamber, wherein the reamer is movable relative to the chamber. Additionally, the tool includes a storage container fluidly connected to the internal cavity of the chamber and effective to receive bone and/or cellular material extracted from the patient, the bone and/or cellular material being extracted during reaming a bone of the patient with the reamer.

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.

The present invention includes a novel procedure and corresponding medical devices for a Percutaneous Posterior Lumbar Interbody Fusion (PePLIF). In PePLIF, the surgeon performs the entire operation percutaneously without the use of a microscope, endoscope, or magnifying loupes. An adjustable retractor system is disclosed that enables the surgeon to percutaneously perform the surgery through accessing the facet joint (and later disc space) that was created by said retractor system. This retractor system provides the surgeon a safe area to work and operate without fear of damaging nerves, blood vessels, or other tissue. An expanding trial may be inserted into and removed from the disc space through the interior of the retractor system to determine the proper size for the expandable cage. The retractor system also enables the expandable cage to be inserted into the disc space.

A method of generating a custom three-dimensional model of a bone is disclosed. A 2D image of the bone is obtained and an orientation and scale of the 2D image are aligned to a pre-determined coordinate system. Based on the 2D image, a representative bone is identified from a library of representative bones that are aligned to the pre-determined coordinate system. Based on the 2D image, an ideal view of a 3D model of the representative bone is selected. Modifications may be made to the 3D model by using additional representative bones from the library. A custom three-dimensional model of the bone is thereby generated.

Reciprocating rasps for the surgical preparation of the bone prior to the implantation of a glenoid or acetabular component with complex geometry are disclosed. Surgical methods for the use of such reciprocating rasps are also disclosed. Some of the methods include inserting a guide pin into the glenoid of the patient, advancing a reciprocating surgical rasp over the guide pin, reciprocating the surgical rasp so as to abrade bone tissue to form a cavity shaped to receive the glenoid component, and implanting the glenoid component in the cavity.

An oscillating decorticating burr assembly for decortication of the articular surfaces of joints of the human body is disclosed. The oscillating decorticating burr assembly comprises a burr, a burr-support post, and a handle. Power is imparted to the assembly by way of a user input on the handle causing oscillation of the burr.

Instrumentation and assembly for arthroscopic elbow surgery which includes a humeral component. The humeral component is installed in a trough formed in the humeral condyle. The trough may be formed by using a plurality of drill pins and a plurality of corresponding cutters (and optionally a template). The two drill pins are passed through the template and drilled into the humerus, and cutters are advanced over the corresponding drill pins to form the trough. The humeral component may be employed in conjunction with an ulnar implant.

A modular surgical tool that is used to insert instruments into the intervertebral disc space of a patient to measure the height of the intervertebral disc space, to prepare the intervertebral disc space for an implant, and to insert the implant into the intervertebral disc space using a plurality of interchangeable tool ends. Advantageously, this modular surgical tool permits multiple insertion angles.

An implant for shoulder arthroplasty includes a stem and optionally a head component or a cup component. The stem is sized and shaped to fit into an intramedullary canal of the humerus. The proximal portion of the stem has a concave taper and the distal portion of the stem has a taper. The distal taper includes an anterior-posterior taper and a medial-lateral taper. The shape of the stem loads the metaphysis of the humerus with a greater load than the load applied to the diaphysis of the humerus.
