Vicryl 5-0 Absorption Timeline
Vicryl (polyglactin 910) 5-0 suture is essentially completely absorbed by 56-70 days, though it loses most of its tensile strength much earlier—retaining approximately 50-75% at 1 week and only 5% by 35 days.
Tensile Strength Loss vs Complete Absorption
The absorption process occurs in two distinct phases that are clinically important:
Early Strength Loss (Functional Timeline)
- Week 1: Retains 50-75% of original tensile strength 1
- Week 2: Approximately 21% tensile strength remaining 2
- Day 35: Only 5% tensile strength remaining 3
This early loss of strength is what matters most for wound support. By 2 weeks post-implantation, the suture has lost most of its functional capacity to hold tissue together 2.
Complete Material Absorption (Physical Timeline)
- 56-70 days: Essentially complete absorption 3
- 90 days: Virtually all remnants absorbed based on histologic examination 4
The guideline evidence confirms that polyglactin sutures used for skin closure maintain adequate tensile support for approximately 1 week, which explains their effectiveness in preventing wound dehiscence compared to non-absorbable sutures removed at 7-9 days 1.
Location-Specific Variations
Important caveat: Absorption time varies by anatomic location. In nasal cavity mucosa, the half-life for spontaneous suture drop was 64-70 days depending on location (septum vs lateral wall) 5. This suggests that mucosal environments may affect absorption kinetics differently than subcutaneous tissue.
Clinical Implications
- For wound support: Plan for the suture to provide meaningful strength for only 2-3 weeks maximum
- For complete dissolution: Expect the physical suture material to be gone by 8-10 weeks
- Inflammatory response: The suture elicits a granulomatous foreign body reaction proportional to its gauge throughout the absorption period 6
The 5-0 gauge specifically produces less inflammatory reaction than larger gauges like 3/0, making it appropriate for delicate closures 6.
