Clinical Evidence

With over 25 years’ experience, the OPRA™ implant system has been used by hundreds of amputees since the world’s first surgery in 1990, through using a bone-anchored prosthesis patients have experienced a revolutionary change that went beyond the functional gains, to improve quality of life1. Other clinically proven outcomes include:

  • Increased range of motion
  • Eliminated pressure, sores and pain caused by the socket
  • Improved sensory feedback (osseoperception)
  • Improved sitting comfort
  • Increased prosthetic use
  • Increased quality of life
  • Improved mobility
