Exam 1- Fracture Review

Question 1

How Quickly do we Expect this Fracture to Heal up?

Answer 1

Rapidly

*Young Animal

Question 2

Describe this Fracture

Answer 2

Transverse Fracture of Radius with Caudal Displacement

Question 3

How Quickly do we Expect this Fracture to Heal once it is Stable?

Answer 3

6-8 weeks

Question 4

Answer 4

Salter Harris Type I and Type V

*Young Dog that is Limping. Radiographs are Done and Everything looks Normal- Recommend Taking Radiographs 2-3 weeks later to Check the growth plates again

Question 5

Answer 5

Skewer Pin

*Used on Short Oblique Fractures

Question 6

What Immobilization Method is Recommended?

Answer 6

Surgical Fixation- DCP, LCP

External Skeletal Fixator

*Comminuted Fracture- Likelyhood that it will Collapse is Higher

Question 7

What Degree of Activity is Present at the Fracture?

Is there Any Evidence of Bone Healing?

Answer 7

Yes- there is a Small Amount of Bone Callus Formation

*This is 6 weeks Later- You would expect it to be Healed. Clearly the Fracture is not Stable

Question 8

Answer 8

Long Oblique

Question 9

If using DCP Plate to Repair the Fracture. What Plating Mode would we use?

Answer 9

Bridging Mode

*Try to get the Bone Fragments as Reduced as Possible

Question 10

Answer 10

Minimally Invasive Plate Osteosynthesis

Question 11

Answer 11

Pin and Tension Band

*Common Fracture that we See in Young Dogs

Question 12

If we use a Pin and Tension Band to Secure this Fracture, is there Any concern for Future Growth/Function of the Limb?

Answer 12

Yes- Concerned about Injury at the Level of the Physis

Question 13

What term Describes the Placement of this Screw?

Answer 13

Lag Screw

*Screw is Placed Perpendicular to the Fracture line which allows us to Compress across the Fracture Line

Question 14

Describe the Fracture

Answer 14

Right Lateral Humural Condyle Fracture with Proximal and Lateral Displacement

*This type of Fracture is seen VERY commonly

*Salter Harris Type IV

Question 15

What Fixation options is/are Recommended?

Answer 15

Surgical Repair- DCP

External Coaptation- Cast (Non Comminuted Transverse Fracture)

Question 16

Answer 16

Yield Point

Question 17

Answer 17

Alignment

Question 18

Answer 18

Question 19

Answer 19

Know what Salter Harris Type III Fracture Looks Like **

*Type III- Through the Physis and down through the Epiphysis

Question 20

Answer 20

Osteomyelitis/Sequestrum

Question 21

Answer 21

Articular Fractures

Question 22

Why is External Coaptation not Recommended for this Type of Fracture?

Answer 22

Fracture Involves a Joint Surface (Articular Fracture)

Question 23

Answer 23

Osteosarcoma

Osteomyelitis

Question 24

Answer 24

External Skeletal Fixator

*Allows you to have Access to the Wound

Question 25

What type of Repair must be achieved? What are the Complications that would accompany a Poor Repair?

Answer 25

**What must be Achieved- Anatomical Reduction (Articular Fracture)** **Complications- Degenerative Joint Disease, Joint Immobility**

Question 26

Answer 26

**Perpendicular**

Question 27

Answer 27

**Spiral**

Question 28

Describe the Fracture

Answer 28

**Closed Right Transverse Comminuted Radial and Ulnar Fracture with Lateral Displacement**

Question 29

Answer 29

**Pin Tract Morbidity/Drainage/Infection**

Question 30

True/False: An **Intramedullary Nail** would be best for Fracture Fixation

Answer 30

**False** **\***Radius is Fractured- Don't ever put an Intramedullary Nail in the Radius

Question 31

How would you Describe this Fracture?

Answer 31

**Closed Left Tibial Avulsion Fracture** _**\***Salter Harris Type 1 Fracture- Across the Physis_

Question 32

What type of Fixation is Recommended?

Answer 32

**Surgery- DCP** **External Skeletal Fixator** **\***This Fracture is a Delayed Union- Using a Cast/Splint will NOT Work

Question 33

Answer 33

**Incomplete (Greenstick)**

Question 34

Answer 34

**Neutralizing Plate**

Question 35

Answer 35

**Quadriceps Contracture**

Question 36

Answer 36

**Intramedullary Pin** **Interlocking Nail**

Question 37

What Immobilization/Fixation Method is Recommended for this Fracture?

Answer 37

**Pin and Tension Band**

Question 38

Answer 38

**70%**

Question 39

Answer 39

**\>/= 0.5 cm**

Question 40

Answer 40

**Cefazolin** _**\***Want to Prevent Staphyloccous from Getting into the Wound- Staph is the #1 Bug that is on the Skin_

Question 41

Answer 41
