Which polymer is biodegradable and used in orthopedic devices?

Solution

1. $\text{PHBV}$ is a biodegradable aliphatic polyester.
2. $\text{Nylon-2-nylon-6}$ is a biodegradable polyamide.
3. $\text{PGA}$ ($\text{polyglycolic acid}$) and $\text{PLA}$ ($\text{polylactic acid}$) are widely used in medical applications due to their biocompatibility and biodegradability.
4. These copolymers are specifically used in orthopedic devices and absorbable sutures.
5. Hence the answer is (C).
