Exam I Study Guide Flashcards
Sarcopenia
Age-related loss of skeletal muscle mass, function, and ability to regenerate.
Effects of sarcopenia
slower gait speed, difficulty completing ADLs requiring significant muscle power
Myositis Ossificans
Abnormal formation of bone within a muscle following a muscle contusion injury
Myositis Ossificans symptoms
prolonged disability, severe pain, loss of function
Myositis Ossificans signs
a large, firm/tender mass within a contused muscle in concert with restricted joint motion
Myositis Ossificans risk factors
hematoma formation, severe contusion, injury to bone or periosteum
Tendinitis
inflammation of tendon
tendinosis
degenerative
Tendon rehabilitation
Modified tension in the line of stress is the optimal stimulus for tendon regeneration, wait until 1 week after injury, progress slowly.
Grade I ligament sprain
mild with no increased laxity
Grade II ligament sprain
moderate with slight laxity (may not involve surgery)
Grade III ligament sprain
severe with complete disruption of ligament fibers and significant laxity (will involve surgery)
Articular Cartilage Type I defect
superficial laceration, doesn’t reach subchondral bone
Articular Cartilage Type II defect
deep, full-thickness injury penetrating to the subchondral bone
osteoporosis causes
estrogen loss, corticosteroids, loss of weightbearing, bed rest, hyperparathyroidism, hyperthyroidism, chronic renal failure
pathogenesis of osteoporosis
Imbalance between osteoclastic and osteoblastic function, Greatest effect on trabecular bone (vertebrae) and metaphysis of long bones
