What Causes Laxity in a Shoulder Injury?
Laxity of the shoulder refers to looseness of soft tissue that surrounds the shoulder joint. A shoulder is generally referred to as lax when the range of its external rotation with the arm on the side exceeds 80 degrees. Laxity may affect the shoulder’s ligaments, tendons, muscle and capsule. The shoulder capsule refers to the area of ligament tissue that surrounds the shoulder like an envelope. Shoulder laxity is usually painless, and is commonly associated with athletes such as swimmers and baseball pitchers who typically cock their arms way back while engaging in sports activities.
