Prosthetics week 1 Quiz

Hey future surgeons! Can you guess which of the following is NOT a reason why surgeons like Dr. Mason and Dr. Mia perform myoplasty during surgery?

• Provide muscle stability in the residual limb.

• Provide some padding over the distal bone.

• Enhance incisional healing.

• Improve the shape of the residual limb.

Hey class! Let's see who can spot the odd one out about neuromas. All of the following are true statements about the formation of neuromas except:

• Both small and large nerves will form neuromas after being severed.

• Surgeons usually sever nerves under tension.

• Nerve ends need to be nestled close to bony prominences.

• Most patients do not have a problem with neuromas.

Imagine you're a surgeon like Dr. William, performing an amputation surgery. What will you do?

• Sever the fibula slightly shorter than the tibia.

• Sever the tibia slightly shorter than the fibula.

• Keep the tibia and fibula the same length.

• Remove the fibula entirely.

Hey Henry, Scarlett, and Hannah! Can you guess which type of flap vascular surgeons usually prefer to use?

• Equal length flaps

• Squeew flaps

• Fishmouth flaps

• Long posterior flaps

During a lively anatomy class, Benjamin asked, "What does the term 'myodesis' mean?" Can you help him out?

• Anchoring muscle to bone.

• Anchoring muscle to muscle.

• Retracting muscles away from the bone.

• Removing unwanted muscles during surgery.

Hey Henry, do you know what osseointegration is?

• The direct attachment of a prosthesis to the body.

• Building a bone bridge between the tibia and fibula.

• Removing the fibula from the residual limb.

• Attaching terminal muscles to the end of the bone.

Imagine you're a top surgeon like Dr. Luna, and you're performing an amputation surgery. All of the following are your goals except:

• Maintain as much length as possible.

• Anatomically stabilize the muscles.

• Enhance surgical healing.

• Create a cosmetic residual limb.

Emma and Luna are discussing the muscles involved in knee flexion at the start of the swing phase. Can you help them figure out which muscles are primarily responsible?

• Hamstring muscles, hip flexor muscles, and plantarflexor muscles

• Hip flexor muscles and hamstring muscles

• Hamstring muscles

• Hip flexor muscles and plantarflexor muscles

During a fun anatomy class, Scarlett and Abigail were discussing which muscle(s) produce(s) the majority of the force that supports the body during midstance through the end of the stance phase. Can you help them figure it out?

• The hip extensor muscles

• The hip extensor muscles and quadriceps

• The quadriceps and gastrocnemius

• The hip extensor muscles and gastrocnemius

Hey there, future physiologists! Imagine Ethan just had an amputation of a limb segment. Can you figure out why his balance might be a bit off even though he doesn't have a neuromuscular disorder? It's because of ___.

• A shift in the location of the center of mass

• Loss of sensory input from the missing limb segment

• Loss of joints and muscles that participate in the support strategies used to maintain or recover balance during perturbation

• All (A, B, C) correctly complete the sentence.
