Spanish term

aletas

Spanish to English Medical Medical: Instruments joint replacement
Description and comparison of surgical products on the market for knee replacement.

Context: "Geometría del vástago:" (precedes each instance below) [Stem geometry]
Instances:
Cilíndrica, redonda con **aletas.
Distalmente Cónica con 8 o 10 aletas.
Ligeramente cónico con aletas de bajo perfil.
Cilíndrica, redonda, con aletas distales.
Cilíndrica, redonda con aletas.
Geometría del vástago: cónico con aletas.

I see they can be cylindrical, round, tapered or have distal.... I've found "pegs" so far, but I have my doubts.

Been looking at:

Thank you.
Note from asker:
Thank you @Taña and @Marie! I chose this answer because I eventually found the term "fin" in documentation concerning the exact models discussed in the text, confirming the examples you provided. Thank you for pointing me in the right direction!!

wings

"Wings" should be another option (see e.g. www.ncbi.nlm.nih.gov/pmc/articles/PMC4972888/ ).
"Pins" are mentioned in this article as well, and 8-10 pins may be more easily arranged around a distal conical stem than 8-10 wings or fins, but I am not sure if a Spanish person would use "aleta" to refer to a pin-type protrusion.
Do you have any images of the stems which are being compared in your text?

As for "pegs": these would be fixation devices attached from the outside rather than protrusions of the stem itself.
Note from asker:
@Anne, thank you very much for the idea and reference, it does make sense, especially concerning the pegs. I did not have direct reliable images but was eventually able to find documentation with images in external resources. Please see above.
