A device configured for use as a medical implant is disclosed herein. The device includes an anchor body having a perimeter wall defining a rim, and a cavity dimensioned to receive an elastic articulating component. At least one lattice region is arranged at least along an inner surface of the perimeter wall adjacent to the rim. An elastic articulating component is configured to fill the cavity and attach to the at least one lattice region.

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 a pontoon shape with opposed elongated partially cylindrical sections connected by a bridge section. The partially cylindrical sections and, in some instances, the bridge section have a porous structure.

In some embodiments, the present disclosure relates to a method of securing an implant into a body of a patient. Initially, the implant is placed into the body of the patient. Then, an impactor tool is used to apply a force to the implant. Subsequent to the application of force to the implant, a portion of an impaction pad on an end of the impactor tool is monitored. When the portion is observed to be deformed, the application of force onto the implant is discontinued.

A medical device, comprises an elongated member having a first end portion and a second end portion opposite the first end portion. A handle is coupled to the elongated member at the first end portion and defines a first striking surface. A second striking surface is coupled to the elongated member between the first end and the second end as a protrusion extending away from the elongated member. A hook is coupled to the second end portion and defines a channel sized and configured to receive at least a portion of a surgical implant.

A system and method for quantitatively assessing a press fit value (and provide a mechanism to evaluate optimal quantitative values) of any implant/bone interface regardless the variables involved including bone site preparation, material properties of bone and implant, implant geometry and coefficient of friction of the implant-bone interface without requiring a visual positional assessment of a depth of insertion. The following description is presented to enable one of ordinary skill in the art to make and use the invention and is provided in the context of a patent application and its requirements.

In accordance with one aspect of disclosure, an inserter tool is provided for an elongate intervertebral implant. The inserter tool includes a body and a distal end portion of the body configured to be connected to the elongate intervertebral implant to orient the elongate intervertebral implant so that a longitudinal axis thereof extends in a predetermined direction. The inserter tool includes an offset member extending from the body. The offset member has an impact surface support portion spaced apart from the body and configured to position an impact surface in alignment with the implant longitudinal axis to permit the impact surface to receive an impact force directed in the predetermined direction.

The present invention relates to a portable medical drill impact attachment device. The device can be used for improving the accuracy and reliability of orthopedic surgeries and procedures by obviating a manual device such as a hammer for creating an impact. The attachment device is used for creating impact forces that can be transferred onto a bone, disc, joint, etc. The device features a housing that includes a rotary motion transformer and an impact mechanism assembly. The attachment transforms the rotational motion of a drill into reciprocal motion, and also enables a user to adjust and control the frequency and energy of the impact. An impactor tool can be detachably-attached to a quick-change tool gripper for providing an impact on a bone, disc or joint of a patient without applying any manual force.

A method of ankle replacement includes forming an anterior cut in a bone and forming a stem hole in a distal end of the bone. The stem hole is formed using a plurality of broaches positioned against the distal end of the bone through the anterior cut. A first portion and a second portion of a stem implant are inserted into the stem hole through the anterior cut in the bone. The first portion is coupled to the second portion using a coupling device inserted through the anterior cut in the bone. The stem implant is impacted into the stem hole using an offset impactor.

An orthopedic instrument in the form of an acetabular cup extractor system for reliably and efficiently extracting an acetabular cup implant from an acetabulum. The system includes a handle assembly, an extractor attachable to a distal end of the handle, and a dome guide assembly having a hemi-spherical dome for engaging the extractor and a centering body extending distally from the hemi-spherical dome for engaging an acetabular implant. The extractor includes a curved, concave guide and a curved blade. The curved, concave guide is sized and shaped to substantially matingly engage with and cover a substantial portion of the hemi-spherical dome. As a result of such an arrangement, a uniform cut is achieved by the curved blade thereby resulting in a minimum of bone being extracted from the acetabulum around the acetabular cup implant during a surgical procedure.

An extraction tool for removing an installed artificial disc from a spine is provided. The extraction tool is impacted between the artificial disc and the vertebrae and engages the artificial disc to allow a surgeon to remove the artificial disc from the spine.
