**Question:** Polyglycolic acid suture material ("Vicryl") is a / an

A. Absorbable
B. Non-absorbable
C. Non-biodegradable
D. Non-degradable

**Correct Answer:** A. Absorbable

**Core Concept:** Polyglycolic acid suture material ("Vicryl") is a type of suture that degrades over time and is eventually absorbed by the body. It is commonly used in surgical procedures due to its ability to reduce the risk of foreign body reaction and infection compared to non-absorbable sutures.

**Why the Correct Answer is Right:** Polyglycolic acid, also known as PGA, is a synthetic monomer derived from glycolic acid. When PGA is used to create a polymer, such as in the production of Vicryl suture, it forms a biodegradable polymer that breaks down into glycolic acid, a naturally occurring substance in the body. This allows the suture to be gradually absorbed and eliminated by the body without causing long-term adverse effects.

**Why Each Wrong Option is Incorrect:**

**Option A (Absorbable)**: While some absorbable sutures are indeed absorbed by the body, not all absorbable sutures are made from polyglycolic acid. For example, silk and catgut are also absorbable suture materials, but they are not biodegradable like Vicryl.

**Option B (Non-absorbable)**: This option is incorrect because Vicryl suture is indeed absorbable, meaning it is absorbed by the body over time. Non-absorbable sutures are made from materials that do not break down in the body and remain in place permanently, such as nylon or monofilament polypropylene.

**Option C (Non-biodegradable)**: This option is incorrect as polyglycolic acid-based absorbable sutures, like Vicryl, are biodegradable. Biodegradable materials are broken down and eliminated by the body's natural processes, whereas non-biodegradable materials remain in place after healing is complete.

**Option D (Non-degradable)**: Similar to Option C, this option is incorrect because absorbable sutures, including Vicryl, are biodegradable and break down into glycolic acid, which is a naturally occurring substance in the body. Non-degradable materials do not break down and are not eliminated by the body's processes.

**Core Concept**: Polyglycolic acid sutures, like Vicryl, are biodegradable and break down into glycolic acid, a naturally occurring substance in the body. This allows the suture to be gradually absorbed and eliminated without causing long-term complications. Non-absorbable sutures, on the other hand, remain in place after healing has occurred and can cause complications such as tissue reaction, foreign body reaction, and potential for infection.

**Clinical Pearls**: When selecting sutures for wound closure, consider the tissue type, the desired duration of suture retention, and the potential complications associated with different types of sutures
