1. Chapter 14 Bone, Joint, and Muscle Injuries

2. Bone Injuries Fracture and broken bone both mean a break or crack in the bone. Two categories: Closed (simple) fracture Open (compound) fracture

3. Recognizing Fractures Use D-O-T-S Deformity Open wounds Tenderness Swelling

4. Caring for Fractures (1 of 2) Perform an initial check for life- threatening conditions. Gently remove clothing covering the injured area. Examine the area by looking and feeling for D-O-T-S. Check blood flow and nerves, using the mnemonic CSM (circulation, sensation, movement).

5. Caring for Fractures (2 of 2) Stabilize the injured part to prevent movement. If the injury is an open fracture, do not push on any protruding bones. Cover the exposed bones with a dressing. Apply an ice pack, if possible. Seek medical care.

6. Joint Injuries Sprain Dislocation

7. Dislocations A dislocation occurs when a joint comes apart and stays apart with the bone ends no longer in contact. The shoulders, elbows, fingers, hips, kneecaps, and ankles are the joints most frequently affected.

8. Recognizing Dislocations Deformity (the main sign) Severe pain Swelling Inability of the victim to move the injured joint

9. Care for Dislocations Check the CSM. Always check the pulses. If there is no pulse in the injured extremity, transport the victim to a medical facility immediately. Use the RICE procedures. Use a splint to stabilize the joint in the position in which it was found. Do not try to reduce the joint. Seek medical care to reduce the dislocation.

10. RICE Procedure R = Rest I = Ice C = Compression E = Elevation

11. Sprains A sprain occurs when a joint is twisted or stretched beyond its normal range of motion. When a joint is sprained, the ligaments are either partially or completely torn. Sprains most often occur in the knee and the ankle.

12. Recognizing Sprains Severe pain Pain prevents the victim from moving or using the joint Swelling Skin around the joint may be discolored because of bleeding from torn blood vessels.

13. Care for Sprains Follow the RICE procedures. Apply ice for 20 minutes. Apply compression for 3 to 4 hours. Repeat the cycles of ice for 20 minutes and 3 hours of compression. Raise the injured part. Swelling in a joint can lead to stiffness in a matter of hours. Keep a joint from swelling by using cold promptly.

14. Muscle Injuries Muscle strain (pull) Muscle cramps

15. Strains A muscle strain, also known as a muscle pull, occurs when a muscle is stretched beyond its normal range of motion and tears the muscle. Inflammation begins immediately after an injury, but it can take 24 to 72 hours for pain and stiffness to begin.

16. Recognizing Strains Sudden, sharp pain in the affected muscle Extreme tenderness when the area is touched Swelling Weakness and inability to use the injured part Stiffness and pain when the victim moves the muscle After a few days, the skin around the injury may be discolored.

17. Care for Strains To care for strains, simply follow the RICE procedures.

18. Cramps A cramp occurs when a muscle goes into an uncontrolled spasm and contraction. Cramps can be divided into two categories: Night cramps Any cramp occurring at night or while an individual is at rest Heat cramps Related to dehydration and electrolyte imbalance

19. Recognizing Cramps Sudden, severe pain, usually in the legs A knotting of the muscle may be felt and sometimes seen. Restricts movement

20. Care for Cramps Have the victim gently stretch the affected muscle. Relax the muscle by pressing and massaging it. Apply an ice pack. Pinch the upper lip hard to reduce calf-muscle cramping (acupressure technique). Have the victim drink lightly salted cool water.
