Upperlimb shoulder and arm

1. The Upper Limb 1 Noel R. San Antonio, PTRP, MSCPD, DPT Dean, College of Health Sciences BS Physical Therapy

2. O steology Shoulder girdle – clavicle and scapula Arm – humerus Forearm – radius and ulna Wrist – carpals Hand – metacarpals and phalanges

3. Shoulder Girdle

4. Clavicle “collar bone” S-shaped and resembles a large, old-style key forms a light strut that connects the upper limb to the thorax the first bone to begin ossification

5. Clavicle Fracture

6. Clavicular Compression of Brachial Plexus, Subclavian Artery, and Subclavian Vein

7. Scapula “shoulder blade” large, flat, triangular bone that lies on the posterior chest wall between the second and seventh ribs Defining features Borders Angles Surfaces Processes

8. Scapula

9. Humerus humer - is Latin for “shoulder” located in the arm (brachium) longest bone of the upper limb three main regions: (1) proximal extremity, (2) body or shaft, and (3) distal extremity

10. Body or Shaft (humerus) deltoid tuberosity radial groove, spiral groove Anatomical neck medial supracondylar ridge lateral supracondylar ridge

11. Body or Shaft (humerus) deltoid tuberosity radial groove, spiral groove Anatomical neck medial supracondylar ridge lateral supracondylar ridge

12. Distal extremity (humerus) lateral epicondyle medial epicondyle Anatomical neck Trochlea coronoid fossa radial fossa olecranon fossa

13. Radius radi - is Latin for “spoke” or “ray”) Features Head Neck Radial tuberosity Body/shaft Styloid process Carpal articular surface
