Elbow
The elbow is not a simple hinge joint. In addition to flexion and extension, the elbow can pronate and supinate.

Elbow Extensionater®
Different elbow injuries require the forearm to be positioned differently when stretching. The unique design of the Ermi Elbow Extensionater improves elbow extension while allowing perfect forearm alignment, no matter the injury.
The Elbow Extensionater is designed based on the principle of three-point bending. It is a small, easy-to-use device that uses a patented pneumatic air bladder technology to improve extension.
Common Indications
- Ulnar collateral ligament reconstruction
- Radius fracture
- Ulnar fracture
- Humerus fracture
- Biceps tear
Patients recovered an average of 15 degrees of elbow extension in five weeks, with most recovering full extension.“I started using your product immediately after surgery and have found it to be a great addition to my recovery. It has definitely helped me extend my elbow to its furthest potential.”
