✓Well SupportedA subluxation can occur without tearing the labrum if the joint is loose.◐Partially SupportedSLAP tears are clinically relevant entities, particularly for younger, very athletic individuals, overhead athletes, weightlifters, and those participating in CrossFit or other aggressive sports.◐Partially SupportedThe labrum enhances shoulder stability by acting like a suction cup.◐Partially SupportedSwimmers, especially females, can develop shoulder laxity due to the demands of strokes like butterfly and backstroke.Partially Supported

Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

The rotator cuff muscles' tendons stabilize the shoulder joint by enshrouding it and tapering from muscle bellies to tendons near the humeral head.

◐Partially SupportedProgressive shoulder laxity requires dynamic stabilizers to compensate for lost static stability.

◐Partially SupportedThe specific type of rotator cuff tear can be predicted based on age, physiology, and trauma mechanism.

◐Partially SupportedTearing the labrum involves separating the labrum from its bony attachment, requiring significant force or repetitive use.

◐Partially SupportedThe shoulder joint's viscous fluid provides static stability.

◐Partially SupportedIn individuals under 40, traumatic rotator cuff tears can result in avulsion fractures.

◐Partially SupportedAvulsion fractures heal better than tendon-to-bone tears.

◐Partially SupportedA subluxation is an incomplete shoulder dislocation that easily self-reduces, while a dislocation requires manual reduction.

◐Partially SupportedA rotator cuff tear diagnosis is heterogeneous and can apply to tears in any of the four muscles, at the muscle-tendon junction, or a complete tendon separation from bone.

◐Partially SupportedRecurrent shoulder dislocations can lead to increased laxity and compliance of shoulder tissues.

◐Partially SupportedRotator cuff tears are rare in individuals under 40 years old.

◐Partially SupportedA shoulder tear extending 40 degrees around the joint is unlikely to result from a single injury.
