Medical homework help?

Left wrist images: Obtained with the patient’s arm taped to an arm board. There are fractures through the distal shafts of the radius and ulna. The radial fracture fragments show approximately 8 mm overlap with dorsal displacement of the distal radial fracture fragment. the distal ulnar shaft fracture shows ventral-lateral angulation at the fracture apex. There is no overriding at this fracture. No additional fracture is seen. Soft tissue deformity is present, correlating with the fracuture sites.

Ok so!!!!!!

When speaking of distal shafts… WHAT is distal to the radius and ulna. They taught that distal meant away from the median plane.. so I don’t get that part.

We were taught dorsal was pertaining to the cavity that contained the brain and spinal cord (posterior)

I basically don’t understand most of this!!!! I was on a roll w/my homeword until I got to THIS! Please help me =)

What year are you? I’m a medical illustrator and this is making relative sense to me – not to be a pain. Just, a lot of doc give us a hard time. sorry to project.

There should be the standard diagram at the beginning of you texts that shows the relationships of these terms to the various parts of the body.

Here’s what it means:

the distal fragment, the part farthest from the center of the body; i.e. the part closer to the wrist .

Dorsal, along with any of the descriptive terms for relative position can be used at any point along the body, so long as it has relevance. The liver is superior to the large intestine. The spleen is lateral to the pancreas and stomach, etc. The metatarsals are distal to the patella…

Hopefully that helps.

On average, an adult human has 206 bones (according to Gray’s Anatomy, but the number can vary slightly from individual to individual), but a baby is born with approximately 270 bones.






Good luck for the future.
