Thumb carpometacarpal (CMC) joint implants include a trapezium implant defining an articulating surface and a cooperating first metacarpal implant with a base portion of the first metacarpal defining an articulating surface. The first metacarpal base articulating-surface is configured to articulate against the trapezium implant articulating surface.

Orthopedic implants having a bone interface member and a water swellable IPN or semi-IPN with a stiffness, hydration, and/or compositional gradient from one side to the other and physically attached to the bone interface member. The invention also includes an orthopedic implant system including an implant that may conform to a bone surface and a joint capsule. The invention also includes orthopedic implants with water swellable IPN or semi-IPNs including a hydrophobic thermoset or thermoplastic polymer first network and an ionic polymer second network, joint capsules, labral components, and bone interface members. The invention also includes a method of inserting an orthopedic implant having a metal portion and a flexible polymer portion into a joint, including inserting the implant in a joint in a first shape and changing the implant from a first shape to a second shape to conform to a shape of a bone.

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 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.

The present disclosure provides an implant, a corresponding method of implantation, and a method of using the same that can be used in orthopaedic joint replacement arthroplasty or hemiarthroplasty and/or an orthopaedic joint resurfacing arthroplasty or hemiarthroplasty. The implant can include a fin portion for receipt in a corresponding slot formed in bone, and the fin portion can support an articulation portion that can be used in resurfacing and replacing portions of articulation surfaces of a joint.

A method of suturing a surgical site after implantation, in a carpometacarpal joint of a hand of a patient, of an implant assembly including a first implant having a first suture and a second suture secured to the first implant via a double-loop configuration, the first suture including a first and second suture ends, the second suture including third and fourth suture ends, the surgical site including a capsular flap substantially C-shaped and attached to a trapezial side of the hand, the method including: extending the first and third suture ends in first and second directions across the implant assembly and through first and second punctures, respectively, in the capsular flap; and extending the second and fourth suture ends through the second and first punctures, respectively, where the second and fourth suture ends do not cross over one another or any other suture end.
