Sept. 8, 2010 You 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: to identify the bones and injuries) Answer all questions on your worksheet. (Try to answer 8 out of 15)
