"Chronic elbow instability presents with pain, apprehension or subluxation of the elbow joint on movement with three types recognised: valgus, posterolateral, and posteromedial."
"In posterolateral instability, the radial collateral ligament (RCL) is commonly injured. A lateral pivot test can be performed to test this ligament. There are other tests such as the posterolateral rotatory drawer test, chair push-up test or prone push-up test, which can also be performed."
"There are a few types of elbow instability with the most common type being posterolateral instability 1. Instability can occur from chronic overuse or post-trauma. Both bony articulation and soft tissue play an important role in providing stability to the elbow joint 2. Three primary static constraints are the ulnohumeral joint, ulnar collateral ligament (UCL) and the radial collateral ligament (RCL)."
