TY - CHAP M1 - Book, Section TI - Chapter 20. Acute Injuries of the Shoulder Complex and Arm A1 - Cline, Steven A2 - Patel, Dilip R. A2 - Greydanus, Donald E. A2 - Baker, Robert J. PY - 2009 T2 - Pediatric Practice: Sports Medicine AB - The anatomy of the shoulder (Figures 20-1 and 20-2) is complex because of the unconstrained nature of the joint, which allows an arc of motion greater than any other joint in the body. The shoulder is stabilized by both bony and soft tissue restraints (Table 20-1). The glenoid forms a small cup, which minimally constrains and stabilizes the humeral head (Figure 20-3). The glenoid labrum, a fibrocartilage lip, adds to the depth and width of the glenoid and is commonly injured in shoulder dislocations and in biceps tendon attachment injuries. The superior, middle, and inferior glenohumeral ligaments stabilize the shoulder through different arcs of motion, and are commonly injured along with the labrum in both adult and younger athletes.1 SN - PB - The McGraw-Hill Companies CY - New York, NY Y2 - 2024/03/29 UR - accessphysiotherapy.mhmedical.com/content.aspx?aid=6977968 ER -
