Sept. 8, 2010You need: Clean paper / Pencil Text options form “You’re the Radiologist” worksheet

Warm Up:

List the four types of bone or joint injuries that we learned yesterday.

You’re the Radiologist!

Diagnosing Bone & Joint Injuries

Your Task

Today, you will learn how doctor’s diagnose bone & joint injuries.

As you go through the powerpoint, follow along on your worksheet. Fill in any missing notes. Answer all questions.

Good Luck!

Diagnosing Bone & Joint Injuries

Two ways that injuries are diagnosed are:

X-RAYS – images that show bones as clearly defined white areas. Draw-backs - Soft tissues (muscles, organs)

are not seen clearly. X-rays are radiation and can damage body cells.

MRI – (Magnetic Resonance Imaging) takes clear images of bones AND soft tissue. Does not damage body cells. Draw-backs – Very expensive!

Who reads X-Rays and MRIs?

Radiology – is the medical field related to reading images of X-RAYS and MRIs.

Radiologists – the doctors who specialize in reading these images.

Common types of skeletal injuries

Fractures – A break in the bone.

Dislocation – A bone comes out of its joint.

Sprain – Ligaments are stretched too far and tear in places. (most common injury)

Arthritis – A disease of the joints that makes movement painful. (usually occurs later in life).

Bone Fractures

Fracture – A break in the bone.

Treatment - Wear a cast while the bone mends. (Surgery may be done to attach the bone

fragments together with pins/screws).

Dislocation

Dislocation – A bone comes out of its joint.

Treatment – Keep the joint stable. A doctor can put the bone back in the proper place.

Dislocated finger OUCH!

Sprains Sprain – Joint is twisted or bent too far. Ligaments are

stretched and tear in places.

(most common injury)

Treatment:

Doctors recommend R.I.C.E.

R = REST the injured joint as it heals.

I = ICE to reduce swelling

C = COMPRESS (wrap tightly)

E = ELEVATE to reduce swelling

Arthritis Arthritis – A disease of the joints

that makes movement difficult and painful. Severe cases can destroy the joint.

Treatment: There is no cure. Pain can be treated with pain relievers, exercise, rest. Surgery to replace a joint may

help.

Hip Replacement

You’re the Radiologist!

Look at the images on the following slides.

Try to diagnose the injury! What bones/joints are shown? Is there an injury? If yes, what type of injury? What treatment do you recommend?

(Use your textbook pg. 311 and this website: http://www.accessexcellence.org/RC/VL/xrays/index.html to identify the bones and injuries)
