Radial Head

A modular, easy-to-assemble alternative to one-piece head/stem designs

The Xl-Nex Gen Modular Radial Head offers an efficient, practical solution for treating degenerative or post-traumatic conditions of the proximal radial head/neck. Its modular design means that the head and stem can be selected independently, allowing the head to closely match the diameter of the articulating surface of the native radial head while ensuring optimal stem fixation. After the stem is implanted, the head is loaded from the side, making it easier to assemble the implant in a tight joint. A set screw secures the head to the stem. The system can be used for primary and revision joint arthroplasty with cemented or uncemented press-fit applications.

  • Modular design allows the head to be replaced without removing the implanted stem
  • Insertion technique allows for preservation of the radial collateral ligament
  • Reproduces natural articulation of radio-capitellar and radio-ulnar joints
  • Four head diameters, each with four different lengths, for a total of 16 head options
  • Four different stem options provide for optimal patient sizing
  • Fully interchangeable parts allow for 75 different combinations
  • Telescoping shaft allows for easy implant insertion and extension of up to 10mm, in 2mm increments
  • The modular design of this implant allows for radial head replacement without surgical disruption of the lateral complex from the humerus. The implant recreates anatomic motion by also allowing for in-situ tensioning and balancing of the supporting ligaments and by maintaining articulation with the capitellum throughout the range of motion.
