The 12K42 ErgoArm plus mechanical elbow joint is suitable for passive and body-powered prostheses.

Energy released when extending the arm is stored with the help of AFB (Automatic Forearm Balance) and subsequently used to support flexion. This makes a smoother motion when swinging the arm, and makes
it easier to lift the forearm. It features:

  • Ratchetless lock
  • Slip-stop function
  • Humeral rotation joint (humeral rotation feature)
  • Adjustable friction
  • Forearm can be shortened (length 305 mm, circumference approx. 250 mm)
  • Choice of 45 mm or 50 mm wrist connection
  • Available in 3 colors (4, 11, 15)
  • Weight: 604 gm

The slip-stop function makes it possible to lower the forearm in a controlled manner without having to fully release and reactivate the lock. The lock can bear a load of up to 230 N at a forearm length of approximately 305 mm. The internal infinite-position lock can be unlocked or locked under load in any position. The Automatic Forearm Balance supports flexion of the joint and enables natural swing characteristics.
