1

What is Osteoarthritis

The wearing away of hyaline cartilage in bone

2

What are the symptoms of osteoarthritis?

pain, stiffness, prominent morning pain, localized tenderness, cracking, crepidus.

3

What is the primary treatment for osteoarthritis?

manage symptoms and correct poor mechanics

4

What is a Bursa?

a fluid filled sac that's primary function is to reduce friction

5

What causes Bursitis?

sudden irritation can cause acute bursitis, while overuse and constant external compression can cause chronic bursitis.

6

Signs and Symptoms of Bursitis

Pain, swelling, and some loss of function

7

Capsulitis

The Result of repeated joint trauma

8

Synovitis

develops from an improperly treated injury

9

What is Chronic Synovitis?

thickening of the synovial lining and compromises joint mechanics and ROM

10

Functions of Bone

Body support, organ protection, movement via lever systems, calcium storage

11

Flat Bones

Ribs, Skull, and Scap

12

Irregular Bones

Vertebrae and Skull

13

Short Bones

Wrist and Ankle

14

Long Bones

humerus, ulna, radius, fib, tib, femur

15

What is the Most commonly Injured Bone type?

Long bones

16

Diaphysis

Shaft - hollow and cylindrical covered by compact bone, medullary cavity contains yellow marrow lined by endosteum

17

Ossification occurs from synthesis of bones and matrix from what two cells?

Osteoblasts & osteoclasts

18

Epiphysis

composed of cacellous bone and has hyaline cartilage covering. PROVIDES ATTACHMENT AREA FOR MUSCLE

19

Periosteum

Dense, white, fibrous covering which penetrates bone via sharpey's fibers. contains blood vessels and oseoblasts

20

How does the diameter of bone increase?

Osteoblasts add bone to the exterior while clasts break down the medullary cavity

21

Wolf's Law

every change in form and function or in its function alone is followed by changes in architectural design.

22

Open Fracture

Displacement of the fractured ends breaking through the surrounding tissue

23

Closed Fracture

little movement or displacement

24

Signs & Symptoms of a fracture

Deformity, pain, point tender, swelling, pain on active and passive motion

25

MOI Fracture

Direct or indirect, sudden, violent, and forceful muscle contraction or force must occur.

26

What is a greenstick fracture?

when a bone bends and cracks, instead of breaking completely into separate pieces.. Most common in children

27

What is a Comminuted Fracture?

A Fracture in which bone is splintered, broken, or crushed into a number of pieces

28

What is a Linear Fracture?

runs parallel to the long axis of a bone

29

What is a Transverse Fracture?

A fracture which the line of break forms a right angle with the axis of bone

30

What is an Oblique Fracture

The line runs obliquely to the axis of bone
