Claims20
A method for manufacturing an anatomic shaped orthopedic joint replacement implant or implants for 1st MPJ, Lesser MPJ's, Ankle, elbow, proximal metacarpophalangeal's, Trapezio-Metacarpal Thumb, and the proximal interphalangeal joints, the method comprising:
- determining the location of a joint implant replacement on a patient;
- providing an image source from a modeled bone selected from a group consisting of human cadaver bones;
- acquiring and producing a three-dimensional (3D) computer file based upon the image source;
- using the 3D computer file to create the orthopedic joint replacement implant, wherein the creation of the orthopedic joint replacement implant comprises:
- providing an indicator/marking to fabricate the implant, so the implant conforms to the dimensions of the one or more human bones,
- providing a stem/anchor to attach or fit on to the collar or head of the implant,
- providing a cap or bearing (usually a plastic or polymer of some kind) to fit on to the collar/head of the implant to prevent metal-on-metal contact;
- and
- inserting the implant into the patient via a surgical procedure.
An anatomic shaped orthopedic joint replacement implant, wherein the head of the joint replacement device for a 1st MTP hemi or total joint, the lesser MTP joints, and the elbow have a ridge and groove, such as the ridge that manipulates the sagittal head called the “crista” on a 1st MTP, for added stability of each of these artificial joint replacement, and a corresponding “groove” on the phalangeal side of a 1st MTP total joint replacement, or on any of the above mentioned joints that would be constructed with a ridge to have corresponding groove to receive it.
An anatomic shaped orthopedic joint replacement implant wherein parts of or all of the implants' head or stem is porous, or includes a porous or lattice structure made via 3D printing or by means of other manufacturing methods, to be implemented in the following joints:
- 1st MPJ, Lesser MPJ's, Ankle, elbow, proximal metacarpophalangeal's, Trapezio-Metacarpal Thumb, and the proximal interphalangeal joints.
An anatomic shaped orthopedic joint replacement implant wherein the cap/bearing set of bearings to be used implement technology we refer to as “bridging bearings”, wherein such a bearing bridges the gap between one sized metatarsal implant and a different sized phalangeal implant, such as for the 1st Metatarsal-phalangeal Joint, Lesser MPJ's, but also to be used in bridging the gap between different sized implants for the total Ankle, elbow, proximal metacarpophalangeal's, Trapezio-Metacarpal Thumb, and the proximal interphalangeal joints to allow mix and match of different sized implants together.
