(Thanks to Israel21c) Israel’s OrthoSpace has developed the InSpace Balloon. It alleviates pain for patients recovering from massive injury to the rotator cuff, a group of muscles and tendons that stabilize and activate the shoulder. 2000 people in Europe and Israel have used the implant invented by Israeli orthopedic surgeon Dr. Assaf Dekel.
