The polymer used for post-operative stitches

Options

A. PHBV
B. Nylon-2-Nylon-6
C. Polylactic acid
D. Buna-S

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the polymer that is specifically used for post-operative stitches.

2. **Analyzing the Options**:
- **Option A: PHBV (Poly beta-hydroxybutyrate-co-beta-hydroxyvalerate)**: This polymer is primarily used in orthopedic services and for controlled drug release, not specifically for stitches.
- **Option B: Nylon 6**: This is a type of synthetic polymer commonly used in fabrics and textiles, not suitable for medical stitches.
- **Option C: Poly Lactic Acid (PLA)**: This is a thermoplastic aliphatic polyester derived from renewable resources. It is known for its biodegradability and is commonly used in medical applications, including post-operative stitches, as it can break down inside the body within six months to two years.
- **Option D: Buna S**: This is a synthetic rubber used for making oil seals and tank linings, and it is not used for stitches.

3. **Identifying the Correct Answer**: Based on the analysis, Poly Lactic Acid (PLA) is the polymer that is used for post-operative stitches due to its biocompatibility and biodegradability.

4. **Final Answer**: The correct answer is **Poly Lactic Acid (PLA)**.
