Techniques for implantable orthopedic pain management devices are disclosed, including incising an opening in a synovial capsule substantially surrounding a joint, using a first tool to form an enlarged opening in the synovial capsule, determining whether to modify the joint, the joint being modified using a second tool if a bone structure coupled to one or more bones is found within the joint and the bone structure is configured to limit articulation of the one or more bones when an implantable device is inserted into the synovial capsule and the joint, and inserting the implantable device into the synovial capsule through the enlarged opening, the implantable device being inserted into the joint using a third tool.

Techniques for implantable orthopedic pain management devices are disclosed, including a body having a body configured to be disposed in a cavity between a first toroidal shape and a second toroidal shape, the body being substantially saddle-shaped and configured to have a first saddle surface aligned on a first axis and a second saddle surface aligned on a second axis, and a channel formed on the body comprising a portion of the first saddle surface and another portion of the second saddle surface.

Techniques for implantable orthopedic pain management devices are disclosed, including a saddle configured to axially align a top contoured surface to a bone surface and to axially align a bottom contoured surface to another bone surface, and a peripheral protrusion disposed on a peripheral surface of the saddle, the peripheral protrusion being configured to maintain dynamic stability of the saddle between the bone surface and the another bone surface.

A device for use during an arthroplasty procedure of a joint of a patient, the joint extending between a first joint end of a first bone and an abutting second joint end of a second bone of the patient. The device includes first and second components that can be mated together. The first component includes an attachment fitting configured for disposing over the first joint end of the first bone and a stem extending from the attachment fitting and suitable for extending along an intra-medullary canal of the first bone. The second component includes an end plate configured to mate with the attachment fitting and a longitudinal plate extending from the end plate and configured for disposing along a medial, longitudinal surface of the first bone. The device also includes at least one fastener for coupling the longitudinal plate to the first bone.

The invention provides surgical methods, devices, apparatus, and systems for supporting the thumb of a patient after basal joint arthroplasty. The embodiments of the invention comprise at least one index metacarpal anchor, at least one thumb metacarpal anchor, at least one sling for positioning the thumb metacarpal anchor relative to the index metacarpal anchor, and at least one anchor washer for tightening and securing the sling(s) without the need to tie the suture(s) components of the sling(s) into knots. Index and thumb metacarpal anchors comprise at least one bone-engaging element for engaging the respective metacarpal. The anchor washer may incorporate one or more sling-engagement mechanisms. Increasing the number of sling-engagement mechanisms associated with the anchor washer increases the surface area of the sling(s) and provides multiple sling elements to provide redundancy and increase the pull force of the sling(s) attachment(s) used to affix the thumb and index metacarpal anchors into a position relative to each other.

The present disclosure pertains to ionic polymer compositions, including semi.- and fully interpenetrating polymer networks, methods of making, such ionic polymer compositions, articles made from such ionic polymer compositions, and methods of making such articles and packaging, for such articles.

A biodegradable joint implant comprises a joint scaffold and a film layer coated on the surface of the joint scaffold. The joint scaffold comprises a first anchor fixing, a second fixing and a flexible spacer, and the first anchor fixing and the second anchor fixing are respectively axially connected to opposite sides of the flexible spacer. The joint implant is made of biodegradable material, and the film layer contains at least one substance that can induce tissue growth. A method for preparing the joint implant and a joint replacement method using the joint implant are also provided.

Implantable orthopedic pain management devices are disclosed, including a body with a top surface having a plurality of regions, each region having a radius of curvature, and a bottom surface having another radius of curvature, the body being configured to be disposed in a joint to prevent contact between one or more bones comprising the joint, the body also not being coupled to the one or more bones, a peripheral protrusion disposed substantially about a perimeter of the body and configured to prevent expulsion of the body from the joint, and a notch disposed substantially about the perimeter of the body and formed with a region of the top surface, the notch having a substantially outward facing vertical surface that is configured to retain the device in position within the joint.

The present disclosure relates to a method for designing an implant for finger bones. In more detail, the present disclosure relates to a method for designing an implant for finger bones, the method including a finger bone image collection step of collecting 3D images of several human finger bones, a finger bone measurement step of measuring the length, cross-sectional width, and thickness of each of the finger bones from the 3D images of the finger bones, and an implant shape derivation step of calculating average values of the lengths, cross-sectional widths, and thicknesses of the finger bones and deriving and storing the shapes of implants for finger bones into a database on the basis of the calculated average values of the cross-sectional widths and thicknesses and shapes of cut surfaces.

The present disclosure pertains to ionic polymer compositions, including semi.- and fully interpenetrating polymer networks, methods of making, such ionic polymer compositions, articles made from such ionic polymer compositions, and methods of making such articles and packaging, for such articles.
