Components connect via dove-tail joint secured by locking screw. Stem cemented into intramedullary canal of radius; head articulates with humerus and ulna. Available in multiple diameters and heights. Used by orthopedic surgeons in clinical/surgical settings to restore joint function and alleviate pain in patients with radial head pathology. Device provides mechanical replacement of damaged radial head; output is physical restoration of joint anatomy. Benefits include pain reduction and improved range of motion. ## Clinical Evidence No clinical data provided; substantial equivalence based on technological characteristics and design similarities to legally marketed predicate devices. ## Technological Characteristics Two-piece hemi-prosthesis; stem material: Ti-6Al-4V; head material: Co-Cr-Mo. Stem features roughened Bond Coat surface. Connection: dove-tail joint with locking screw. Fixation: bone cement. Dimensions: 18mm, 20mm, 22mm head diameters; head heights 8-20mm. Sterilization: not specified. ## Regulatory Identification An elbow joint radial (hemi-elbow) polymer prosthesis is a device intended to be implanted made of medical grade silicone elastomer used to replace the proximal end of the radius. ## Predicate Devices - Liverpool Radial Head Replacement Device ([K012551](/device/K012551.md)) - Radial Head Surface Replacement (Implex Corp.

K984290), Radial Head Implant (Avanta Orthop., Inc., K002644) and Modular Radial Head (Wright Medical Tech. Inc., K991915) Device Description: The Modular Radial Head Replacement Device is a two-piece prosthesis consisting of a stem (Ti-6Al-4V) and a head (Co-Cr-Mo). The tapered stem is cemented into the intramedullary canal of the radius. The head has a highly polished concave surface to articulate with the natural bone of the humerus and ulna. The proximal portion of the stems are roughened with a Bond Coat surface. The components connect via a dove-tail joint secured by a locking screw. The device is available in three diameters, 18mm, 20mm and 22mm with head heights that vary from 8 to 20mm. Stems are available in six diameters with varying lengths. Intended Use: The Modular Radial Head Replacement Device is intended for: - 1) Replacement of the radial head for degenerative or post-traumatic disabilities presenting pain, creptation, and decreased motion at the radio-humeral and/or proximal radio-ulnar joint with: - a) Joint destruction and/or subluxation visible on x-ray - b) Resistance to conservative treatment - 2) Primary replacement after fracture of the radial head - 3) Symptomatic sequelae after radial head resection - 4) Revision following failed radial head arthroplasty The device is intended for single use with bone cement. Summary of Technologies: The technological characteristics (materials, design, sizing, and indications) of the Modular Radial Head Replacement Device are similar to or identical to the predicate devices.
