12K42 ErgoArm Plus with AFB



For use with body-powered terminal devices.

Infinite Possibilities

  • Engage the unique SlipStop function with a slight pull on the cable.

  • Reposition the arm without fully cycling the lock (only 7mm excursion) and then lock wherever needed.

All elbows lock and unlock completely for an infinite number of positions - even under a 50 lb. load.

Innovative Wiring System

Power and signal wires are already integrated into the elbow with our Easy Plug, protecting the wires from damage while also creating a more natural look and feel.

Adjustable Automatic Forearm Balance (AFB)

AFB compensates for the weight of the forearm and gives it a comfortable and natural-looking swing.

Compact Turntable

  • Turntable is so compact that the distal end of socket can be brought within 3cm of the elbow axis.

  • Ideal for long transhumeral and elbow disarticulation amputees.

  • Easy-access external humeral rotation friction adjustment can be set with a coin.

Versatile

All ErgoArm elbows come in two sizes, 45mm and 50mm, and work in conjunction with Otto Bock 45mm and 50mm wrist units.

With the new 13Z68 adapter it's easy to connect sockets built for other systems to ErgoArms.
