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 Hip Joint Hinge Joint Ball & Socket Joint Pg. 392

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 1 st 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 As bones grow Osteomalacia = adults Growth completed Can Rickets & Osteomalacia be cured? YES By adding calcium & vitamin D to your diet.
