Care & Problems of the
Skeletal System
Osteoporosis
 Thinning & weakening of bones.
 CB: loss of calcium from bone tissue.
 Become brittle – fracture easily from
fall/impact/effort.
Normal bone structure
Thinning / weakened
bone structure
Pg. 391
Joint Injuries
Sprain: A tear in a ligament from stretching it too
far.
 Most common Joint Injury
 CB: sudden twist or impact
Torn Ligament

Strain: Tear in a Muscle or Tendon
Muscle Tear
Dislocation: End of a bone is pulled out of its joint
Ligaments severely stretched/torn.
Knee Joint
Hinge Joint
Pg. 392
Hip Joint
Ball & Socket Joint
Torn Cartilage: Cartilage torn if the joint
receives a strong force.
Ruptured Disc: Intervertebral disc bulges
from the joint & pressed on a
nerve.
 Numbness / intense pain
 Lower back discs more
likely to rupture – supports
majority of body weight.
Pg. 392
Bursitis: Inflammation of a sac near a joint.
A bursa is a tiny fluid-filled sac that
functions as a gliding surface to reduce
friction between tissues of the body.
Pg. 393
Bunion: Painful swelling of Bursa in 1st joint
of big toe.
CB: Inflammation or a type of arthritis
May require surgery
Pg. 393
Arthritis: an inflammation of a joint.
Osteoarthritis - most common form
 CB: normal wear & tear that occurs as you
grow older.
 Painful and stiffening of joint.
 Can occur in any joint.
Cartilage wears away.
Bones rub against each other
Pg. 393
Repetitive Motion Injury:
 Damage to tissues caused by prolonged,
repeated movements.
Computer work
Sewing
Assemble line work
Most common RMI:
CARPAL TUNNEL SYNDROME
Pg. 393
CARPAL TUNNEL SYNDROME
 Swollen ligaments & tendons in wrist
 Causes numbness, burning, or tingling
sensations in the thumb and forefinger,
pain and weakness in the hand.
Pg. 393
3 Factors for Strong Bones
 Diet – calcium, phosphorous, & Vit. D
 Exercise, weight bearing activities
 Estrogen: controls body’s calcium
absorption
& deposits it in bones.
Pg. 390
Rickets & Osteomalacia
 Softening of bones.
 CB: inadequate amounts of Vit. D &
calcium.
Abnormally curvatures  bones aren’t hard enough to
support weight w/o bending.
Rickets & Osteomalacia
Rickets = Children
Osteomalacia = adults
As bones grow
Growth completed
Can Rickets & Osteomalacia be cured?
YES 
By adding calcium &
vitamin D to your diet.
