Development of the AcromionThe acromion has three secondary ossification centers: preacromion, mesoacromion, and metacromion.These centers appear between 14 and 16 years of age and gradually fuse in sequence:The basiacromion is the primary ossification center.I..

https://youtu.be/GLGz8BKbacQ📌 Rotator Cable OverviewThe rotator cable is a thick, fibrous structure in the shoulder, resembling a suspension bridge. It transfers forces across the rotator cuff and helps anchor the tendons to the tubercles of the humerus. ✅ Function of the Rotator CableAnchors rotator cuff tendons to the humerus.Assists in stabilizing the glenohumeral joint.Disperses stress on t..

IncidenceFound in 15% to 45% of asymptomatic shoulders, often linked to ageing and rotator cuff pathology.  2. ClassificationClassified by location: bare area, lesser tuberosity, anterior greater tuberosity, and posterior greater tuberosity.  3. Bare-Area CystsMost common type, located in the poster..

Overview of Muscle ArchitectureThe infraspinatus muscle consists of two distinct portions:These portions are connected at the superior muscular area but clearly separate in the distal tendinous region.2. Tendinous CharacteristicsThe tendinous portion is primarily derived from the oblique part:3. Distinctive Attac..

Five Histologic Layers of the Supraspinatus and Infraspinatus Tendons1. Layer 1: Superficial LayerThickness: ~1 mmComposed of fibers from the coracohumeral ligament.2. Dense Parallel Tendon FibersThickness: 3–5 mmDensely packed parallel collagen fibers.Stronger than layer 3 by twofold.Prone to intrasubstance tears between this layer and layer 3.3. Deep Layer with Non-Uniform Collagen Orientation..
