Which is an example of a synthetic nonabsorbable polymer?
a. Dermal silk
b. Surgical cotton
c. Stainless steel suture
d. Surgical nylon
ANS: D
Nylon is a polyamide polymer derived by chemical synthesis from coal, air, and water. It produces minimal tissue reaction. Nylon has high tensile strength, but it degrades by hydrolysis in tissue at a rate of about 15% to 20% per year. It may be used in all tissues where a nonabsorbable suture is acceptable.
