A very versatile brace that can go from 90 degrees (elbow cocked at right angle during recovery) to 180 degrees (arm straight). My wife used this after breaking her elbow, having it pinned, and being in a sling for almost a month. Contractures inevitably follow, and this clever device enables you to either hold the joint at a specific angle or gently put traction on the joint (for whatever length of time you can tolerate.) Heavily padded and comes with two turnbuckles; standard plus a larger stainless steel unit from a marine supply store. Like-new condition.
