1. 1.03 Functions and disorders of the skeletal system

2. Functions of Skeletal System
1. Hemopoiesis – formation of red blood cells
in the diphysis of the long bones.
Mineral storage- Calcium, phosphorus, vit.d
Movement-with help from the use of our muscle.
Protection-of internal organs.
Support-framework for our body.

4. DISORDERS OF THE SKELETAL SYSTEM
Arthritis= arthr/o -joint
itis - inflammation
Two kinds of Arthritis:
1. Osteoarthritis
2. Rheumatoid Arthritis

5. DISORDERS OF THE SKELETAL SYSTEM
Arthritis
Osteoarthritis
Caused by aging, trauma, obesity, family history
Bone hits bone
Symptoms: painful joints, swelling, deformity of the joint.
Treatments: rest, exercise, anti-inflammatory, surgery

6. DISORDERS OF THE SKELETAL SYSTEM
Arthritis
Rheumatoid arthritis
Caused by auto-immune response. Mostly hands and feet.
Symptoms: stiffness, swelling, deformities.
Treatment: Aspirin(ASA), rest, ROM

7. DISORDERS OF THE SKELETAL SYSTEM
Gout
Metabolic disorder caused by overproduction of uric acid.
Over ingestion of proteins/obesity
Painful/swelling in joint of large toe.
Treatment: Dietary restrictions on proteins, medications.

8. DISORDERS OF THE SKELETAL SYSTEM
Osteoporosis
Caused by a metabolic disorder. Low calcium intake
Mostly women
Decreased bone density
Treatment: Early prevention,
reg exercise, supplements

10. DISORDERS OF THE SKELETAL SYSTEM
Rickets
Pediatric condition(third world countries)
Lack of vitamin D
Deformed, weak legs, bowing
Treatment: Dietary increase of Vit.D, sunlight

11. DISORDERS OF THE SKELETAL SYSTEM
Abnormal spinal curvatures
Kyphosis Lordosis Scoliosis
hunchback swayback s-curve

12. SKELETAL SYSTEM TRAUMA
DISLOCATION VS. SUBLUXATION
Subluxation occurs when the joint only comes out of place partially and goes back into place. move the affected area to move it back into place. This is less traumatic and lower in severity than a dislocation.
Dislocation happens when ball portion of the joint comes out completely from its socket. Usually requires surgery. This is more severe, more painful and requires more treatment than a subluxation.

Fractures-
broken bones

Fractures
Open or compound
DOES break through the skin…….
Increase risk of infection

17. SKELETAL SYSTEM TRAUMA
Fractures
Comminuted- fragmented, shattered, pieces of bone
Gunshot, crushing injury

18. SKELETAL SYSTEM TRAUMA
Fractures
Greenstick-
CHILDREN
incomplete break
splintering
1.03 Understand the functions and disorders of the skeletal system

19. SKELETAL SYSTEM TRAUMA
A sprain is an injury to a ligament, the tough, fibrous tissue that connects bones to other bone. Ligament injuries involve a stretching or a tearing of this tissue.
A strain, on the other hand, is an injury to either a muscle or a tendon, the tissue that connects muscles to bones. Depending on the severity of the injury, a strain may be a simple overstretch of the muscle or tendon, or it can result in a partial or complete tear.
