MSK Patho

Question 1

Amputations

Answer 1

Considered to be an avulsion involving complete loss of body part. Wound edges are typically rough/jagged

Question 2

Compartment Syndrome

Answer 2

When blood is confined within compartment formed by fascia. swelling limited to available space, no blood flow causes tissue death

Question 3

Contusions

Answer 3

Closed wound with soft tissues damaged underneath. Presents as painful edema and ecchymosis

Question 4

Disclocations

Answer 4

Bone totally displaced from joint, articular surfaces no longer intact. Muscle spasms lock bone in place

Question 5

Necrotizing Facaiitis

Answer 5

Flesh eating disease. Involves rapid tissue death from bacterial infection. Hallmark sign is severe pain out of proportion to what is observed in physical exam

Question 6

Sprains

Answer 6

Occur when ligaments are stretched or torn, pain and swelling present, unwillingness to use joint

Question 7

Strains

Answer 7

Occurs in injury to muscle/tendon. Result of violent contraction or excessive stretch. Pain and swelling present

Question 8

Deep Vein Thrombosis

Answer 8

blockage of a blood vessel by a blood clot. Clot can travel to an artery, causing obstruction that leads to ischemia and infarction. Signs are swelling of extremity and erythema

Question 9

Complete vs incomplete fractures

Answer 9

Complete- break travels all the way through bone
incomplete- bone is damaged but still intact

Question 10

Open (compound) vs closed (simple) fracture

Answer 10

Open (compound)- skin is broken and bone is visible
Closed (simple)- Skin not broken

Question 11

Oblique fracture

Answer 11

Fracture that occurs diagonally across bones shaft

Question 12

Comminuted

Answer 12

Bone is splintered or crushed and is found between two main bone fragments. My jaw was a comminuted break (bag of bone shards)

Question 13

Pathologic fracture

Answer 13

Caused by other abnormal illness (tumor displacing bone tissue)

Question 14

Greenstick fracture

Answer 14

A partial fracture in which one side of the bone is broken and the other side bends like a green twig. Common in children

Question 15

Impacted fracture

Answer 15

One end of the fractured bone is forcefully driven into the interior of the other. Bones “impact” each other

Question 16

potts fracture

Answer 16

Fracture of the distal end of the fibula (lateral leg bone), with serious injury of the distal tibial articulation.

Question 17

Colles fracture

Answer 17

Fracture of the distal end of the lateral forearm bone (radius) in which the distal fragment is displaced posteriorly

Question 18

Osteogenesis Imperfecta

Answer 18

Inherited disorder,mutation affects collagen which impacts bone and joint development. Causes thin and underdeveloped bones prone to fractures

Question 19

Rheumatoid Arthritis

Answer 19

Inflammation of connective tissue (primarily joints) and has no known cause. Presents as swelling,pain and loss of function

Question 20

Osteoarthritis

Answer 20

Non-inflammatory joint disease. Caused by loss of articular cartilage in synovial joint. Presents as pain,stiffness and reduced mobility

Question 21

Osteomyelitis

Answer 21

Acute or chronic infection of the bone. Caused by infection via bloodstream,trauma or integumentary infections
