[Essential Path] Clueless About Rotator Cuff Anatomy? Here’s the Basics!

https://youtu.be/jo_6SkaWMIYClueless About Rotator Cuff Anatomy? Here’s the Basics! Summary of Rotator Cuff Anatomy 1. Overview The rotator cuff is a group of four muscles (supraspinatus, infraspinatus, teres minor, subscapularis) and their tendons, crucial for stabilizing the glenohumeral joint. 2. Posterosuperior CuffSupraspinatus: Key for shoulder abduction; most frequently injured tendon.Inf..

Articular-surface partial-thickness tear with intratendinous horizontal splitting tear of the infraspinatus tendon Intact supraspinatus tendon The footprint of the supraspinatus on the greater tuberosity is much smaller than previously believed, and this area of the greater tuberosity is actually occupied by a substantial amount of the infraspinatus. The anterior part of the infraspinatus partia..

Relatively small, triangular, the anteromedial footprint of the supraspinatus tendon at the superior facet and a comparatively large, trapezoidal footprint of the infraspinatus tendon occupying the anterolateral portion of the superior facet and the entire middle facet. The footprint of the supraspinatus had a triangular shape, which tapered away from the joint capsule. The footprint of the infr..

Supraspinatus calcific tendinitis is well known; However, calcific deposits may occur less commonly in other structures in and around the shoulder joint (The long head of the biceps tendon, labrum, and periarticular soft tissue). In view of involvement of these other sites, the more appropriate term for the condition is calcific periarthritis Small calcifications may sometimes be missed, especia..

Acute calcific periarthritis (ACP) is a self-limiting, monoarticular, peri-articular process of dystrophic mineral deposition and adjacent inflammation. The majority of cases involve the shoulder. Less commonly, there may be involvement of the hip, knee, ankle, foot, elbow, wrist, and fingers. Patients present with a sudden onset of pain, localized swelling, erythema, tenderness, and restricted ..

Here is a large superolateral humeral head erosion and synovial thickening and joint effusion. Is this a Hill-Sachs Lesion? Hill-Sachs lesions are strongly associated with anteroinferior glenoid fracture, anteroinferior glenoid labrum tear (Bankart lesion), and joint capsular injury. However, there are several common non-traumatic bones and joint diseases that rarely mimic Hill-Sachs lesions. An..
