A

oddly shaped with various bony projections that interact with other bones, provide sites for muscle attachment (spinal vertebrae)

Q

features of joints

A

where two or more bones meet
cartilage cushions the joint
synovial membrane secrets fluid to lubricate the joint
ligaments hold together joint

Q

cartilage definition

A

connective tissue that cushions joints

17
Q

synovial membrane definition

A

lines freely moveable joints, secret fluid that lubricates

18
Q

normal findings of the musculoskeletal system

A

muscle strength
ROM
fine movements
maintain posture
maintain balance
flexibility

19
Q

factors influencing mobility

A

illness
pain
motivation
education
environment
culture
lifestyle
injury

20
Q

effects of immobility

A

deconditioning
contractures
muscle atrophy
orthostatic hypotension

21
Q

foot drop definition

A

permanent dorsiflexion, the foot is stuck extended down

22
Q

age-related changes in the musculoskeletal system

A

strength decreases
bones become brittle, break easily
joints stiffen and become painful
height gradually decreases
mobility therefore decreases

23
Q

factors of falls

A

mechanical/environmental:
improper use of equipment, poorly fitting shoes, cluttered room, spills
client:
decreased senses, conditioned, cognitive impairment
caregiver:
not giving call bells, missing safety checks, body mechanics, trying to save resident, missing walking aids

24
Q

what to do when client falls

A

help lower to ground is possible
dont catch them
stay with them
call for help

25
features of fractures
bone is broken and surrounding tissues are also damaged open and closed (bone poking out or not) look for bent/out of position, pain, swelling, loss of function, protruding bone, bruising
26
features of hip fractures
common in older adults mostly women shortening of limb or out of position lead to post-operative complications (catching illness, pressure ulcers) mortality is at risk from these
27
amputation definition
traumatic (accidental) or surgical phantom pain is common may have prosthesis assess skin for friction, pressure, moisture
28
osteoporosis definition
bones become more porous/hollow, brittle, and fracture easily common in spine, hips, wrists caused by lack of estrogen (women), calcium, vitamin d, exercise, and smoking can prescribe estrogen, get braces, strength training exercises, walking aids
29
arthritis definition
loss of joint function or inflammation 100+ different types some affect connective tissue, can have systematic affects cause is unknown
30
osteoarthritis definition
cartilage wears away, decreased cushioning meaning bones rub together may see bone spurs, thickening grown on bone affects weight-bearing joints no cure, most common type, common in overweight people
31
rheumatoid arthritis definition
autoimmune disease normal tissue is replaced with scar tissue leading to deformities onset and progressive severe inflammation
32
caring activities for arthritis
positioning ice/heat medications weight loss aids comfort safety
33
Contractures
Lack of joint mobility from abnormal shortening of muscle
34
Deconditioning
Loss of muscle size, strength, and function (or muscle atrophy) from inactivity
35
Muscle atrophy
Decrease in size or wasting away of muscle
36
Osteomyelitis
Inflammation of the bone marrow serious bone infection acute or chronic When bacteria/fungi spread to bone through the bloodstream, fractures, or surgery
