Intended Use

The Ignite Orthopedics Revolution Radial Head is indicated for:

  • · Replacement of the radial head for degenerative or post-traumatic disabilities presenting pain, crepitation, and decreased motion at the radio-humeral and/or proximal radio-ulnar joint with:
    • o joint destruction and/or subluxation visible on x-ray; and/or
    • o resistance to conservative treatment.
  • · Primary replacement after fracture of the radial head.
  • · Symptomatic sequelae after radial head resection.
  • Revision following failed radial head arthroplasty.
Device Description

The Revolution Radial Head is a one-piece, stemmed radial head replacement. The radial head is available in diameters of 19, 22 and 25mm. The radial stems range from 5.5 to 8.5mm in diameter and from 21 – 24mm in length.

The Revolution Radial Head is manufactured from wrought CoCrMo alloy conforming to ASTM F1537.

The system is provided with a set of accessory instruments designed for preparation of the implant site and insertion of the implants into bone.
