Figure 5-1. Normal ACJ. Schematic drawing of an anterior view of the right shoulder. The normal ACJ contains a variable intra-articular disk that ranges from [A] complete [B] to meniscoid-like…

Figure 6-1. Anterior shoulder dislocation. [A] Radiographic AP view shows humeral head normally aligned with the glenoid. [B] Lateral view depicts anterior shoulder dislocation.     The compression fracture  results…

Figure 2-1. Normal postoperative finding. [A] Positioning of the probe. [B] Corresponding 12-5 MHz US image obtained after subacromial decompression demonstrates expected loss of the normal convex contour of the…

Figure 5-20. GHJ effusion distending the posterior recess. [A] Positioning of the probe. [B] Corresponding 12-5 MHz US image shows the normal recess and articular cartilage (arrowheads) located deep to…

Figure 5-29. SClJ. Schematic drawing of an anterior view of the SClJ. An articular fibrocartilaginous disc divides the joint into two separate synovial spaces. The joint is supported by a…

Figure 9-2. Deltoid muscle tear. [A] Short-axis 12-5 MHz US image shows a discrete tear (asterisk) of the deltoid muscle (delt). [B] Corresponding long-axis 12-5 MHz US image. Hum= humerus….

Figure 3-1. Rotator interval: proximal level. [A] Positioning of the probe for short-axis view of the LHBBT (see figure 1-11A for arm positioning). [B] Corresponding 12-5 MHz US image demonstrates…

Figure 10-3. Incomplete tear at the musculotendinous junction of the pectoralis major. [A] Positioning of the probe. [B] Corresponding 12-5 MHz US image depicts an incomplete tear (asterisks) located at…

Figure 1-4. Acromion shape on coronal plane. Schematic drawing of a coronal view of the shoulder. To define lateral acromial angulation, a line is drawn through the mid-substance of the…

    The insertions of the supraspinatus and infraspinatus tendons have been further described as a five-layer structure (table 1-2).4 Layer two comprises the main portion of the tendons, though…
