The present disclosure provides for a wrist arthroplasty system and method that enable an expedient surgical procedure, maintain wrist motion, and reduce the likelihood of implant loosening. The system includes a capitate implant, a radial implant, and a resection instrument. The capitate implant includes a convex head formed to interface with a concave socket of the radial implant. The capitate implant includes a single stem formed to be secured within a patient's capitate bone. The radial implant includes lips formed to increase wrist joint motion and to help prevent dislocation of the capitate implant from the radial implant. The resection instrument may be used in combination as a measurement tool for determining the proper implant size, a guide for properly positioning the implants, and a trial tool for testing trial implant components before securing the final radial and capitate implants.

Wrist arthroplasty system and method

The present disclosure generally relates to an elbow arthoplasty prosthesis that includes an ulnar component, a humeral component, one or more articulation liners, and a retention trap. The ulnar component includes a spherical bearing head that can be inserted into the humeral component in a number of orientations. The articulation liners and the retention trap are operatively engaged to the humeral component to retain the ulnar component within a humeral socket. The present disclosure also relates to methods of assembling and implanting the prosthetic device.

Elbow arthroplasty apparatus, system, and method

A method of bone fixation. A guide device may be disposed such that a first portion of the guide device is disposed longitudinally in a medullary canal of a bone and such that a second portion of the guide device is disposed outside the bone and defines a transverse path across the bone and intersecting the medullary canal. A transverse hole may be formed in the bone along the transverse path, and a fastener may be disposed in the transverse hole. A rod may be placed longitudinally in the medullary canal such that a threaded portion of the rod enters an aperture of the fastener and engages the fastener at the aperture to lock the rod to the fastener. The first portion of the guide device may be removed from the medullary canal after the step of forming a transverse hole and before the step of placing a rod.

Rod-based system for bone fixation

System, including methods and apparatus, for treating orthopedic conditions using a rod member structured for placement in a medullary canal of a bone and including at least one locking aperture with an internal thread structure. In some embodiments, the internal thread structure may include two or more thread leads disposed adjacent the same end of the locking aperture, two or more interspersed internal threads, and/or a thread depth substantially less than that of a corresponding threaded fastener for the locking aperture.
