Good nutrition
Calcium

Phosphorus
Physical activity
Regular checkups

Comminuted- Shatters
Compound- Thru skin

12. Injuries to joints Dislocation- Bone slips out
Torn Cartilage- Twisting or sharp blow
Bursitis- Inflammation of bursa sac
Arthritis- Inflammation of joint

13. Other Problems Scoliosis- “S” curvature of the spine
Osteoporosis- Bone become weak & brittle
