Selecting an absorbable surgical suture involves more than choosing a material that eventually dissolves. Its composition, strength retention, absorption profile and needle configuration all matter when evaluating a product for a particular procedure.
Polyglactin 910 and Polyglycolic Acid (PGA) are two synthetic absorbable suture materials available from Universal Sutures. Although they share several characteristics, they have different polymer compositions and product specifications.
What Are Polyglactin 910 Sutures?
Polyglactin 910 is a copolymer made from 90% glycolide and 10% L-lactide. Universal Sutures offers this material under the UNISYNTH brand as a braided, coated suture in violet and undyed options.
The published product specifications list approximately 70% tensile strength retention at 14 days and complete absorption through hydrolysis within approximately 56–70 days. Explore UNISYNTH Polyglactin 910 sutures.
What Are Polyglycolic Acid Sutures?
Polyglycolic Acid sutures are made from a homopolymer of glycolide. Universal Sutures offers standard PGA sutures under the UNIGLYDE brand.
These sutures are also braided and coated. The published specifications describe approximately 75% initial tensile strength retention at 14 days, 50% at 21 days and complete absorption within approximately 60–90 days through hydrolysis. Explore Polyglycolic Acid sutures.
Polyglactin 910 vs PGA: Product Comparison
The following comparison reflects Universal Sutures’ published standard product specifications. It should not be applied automatically to other brands or fast-absorbing variants.
| Feature | Polyglactin 910 — UNISYNTH | PGA — UNIGLYDE |
|---|---|---|
| Polymer composition | 90% glycolide and 10% L-lactide | Glycolide homopolymer |
| Construction | Braided and coated | Braided and coated |
| Coating | Poly(glycolide-co-L-lactide) and calcium stearate | Polycaprolactone and calcium stearate |
| Absorption mechanism | Hydrolysis | Hydrolysis |
| Approximate complete absorption | 56–70 days | 60–90 days |
| Approximate strength retention at 14 days | 70% | 75% |
| Listed wound support | 28–30 days | 28–30 days |
| Colour options | Violet and undyed | Violet and undyed |
Specifications are available on the Polyglactin 910 product page and PGA product page. Refer to the current instructions for use for the selected product code.
Why Absorption Time and Strength Retention Matter
Complete absorption and wound support describe different aspects of suture performance. A suture can remain in tissue after it has lost much of its original strength.
Consequently, a longer absorption period alone does not establish that a product provides longer or better wound support. Likewise, the listed strength-retention percentages should not be treated as proof of clinical superiority: they are product specifications, not results from a direct comparative clinical trial.
Which Suture Should You Choose?
There is no single choice that suits every procedure. Selection should consider the tissue being approximated, the required support period, the surgical technique and the product’s approved indications.
For procurement teams, a useful comparison also includes practical details:
- Does the requested product code match the surgeon’s preferred material?
- Are the USP size, strand length and needle configuration correct?
- Is the requirement for a standard or fast-absorbing product?
- Are current instructions for use and technical documents available?
- Do the packaging quantity and delivery schedule meet purchasing requirements?
Comparing equivalent configurations makes quotations more meaningful. A price comparison between different needle types, strand lengths or pack quantities can be misleading.
Explore Absorbable Sutures from Universal Sutures
Universal Sutures offers UNISYNTH Polyglactin 910 and UNIGLYDE PGA sutures within its surgical suture range.
For product specifications or a bulk quotation, share your required material, USP size, suture length, needle details and order quantity with Universal Sutures. This helps the team identify the relevant product codes and prepare a quotation aligned with your requirements.
Final clinical selection should follow the treating surgeon’s assessment and the current product instructions for use.
