DISORDERS OF THE SKELETAL SYSTEM
1.03 Understand the functions and disorders of the skeletal system
4
Arthritis= arthr/o -joint itis - inflammation
Two kinds of Arthritis: 1. Osteoarthritis 2. Rheumatoid Arthritis
DISORDERS OF THE SKELETAL SYSTEM
1.03 Understand the functions and disorders of the skeletal system
5
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
Arthritis Rheumatoid arthritis Caused by auto-immune
response. Mostly hands and feet.
Symptoms: stiffness, swelling, deformities.
Treatment: Aspirin(ASA), rest, ROM

7
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.

Osteoporosis Caused by a metabolic
disorder. Low calcium intake
Mostly women
Decreased bone density
Treatment: Early prevention,
reg exercise, supplements

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

11
Abnormal spinal curvatures Kyphosis Lordosis
Scoliosis hunchback swayback s-
curve

12 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.

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.
