Quick Answer
Choosing the right surgical suture requires evaluating four key factors: the type of surgery being performed, the tissue being approximated, the required duration of wound support, and the desired absorption timeline. Absorbable sutures are preferred for internal tissues, while non-absorbable sutures are chosen for permanent support or external skin closure.
Assess the Surgery Type
Different surgical specialties have distinct suture requirements shaped by tissue type, healing rates, infection risk, and the need for suture removal. Start by identifying the procedure and specialty to narrow the field of appropriate sutures.
| Surgery Type | Recommended Characteristics | Typical Products |
|---|---|---|
| General Surgery (fascial) | Absorbable, braided, 28-35 day support | DesmoNex, Absorbex |
| Cardiovascular | Non-absorbable, monofilament, permanent strength | DesmoMid, DesmoSter |
| Obstetrics / Gynecology | Fast-absorbing, avoids removal | DesmoNex Rapid, DesmoCryl Rapid |
| Orthopedic | Long-term or permanent tensile strength | DesmoCapro, DesmoPol |
| Plastic / Reconstructive | Monofilament, low reactivity, fine gauge | DesmoCryl, DesmoPol |
| Ophthalmic | Very fine gauge (8/0-10/0), precise handling | DesmoNex, DesmoSilk |
| Pediatric | Fast-absorbing, avoids traumatic removal | DesmoNex Rapid, DesmoCryl Rapid |

Determine Tissue Requirements
Each tissue type has a distinct healing timeline and mechanical environment. Suture selection must match the tissue's need for support — using a suture that loses strength too quickly risks wound dehiscence; using one that persists too long can cause unnecessary inflammation.
Studies show appropriate suture-tissue matching reduces post-operative complication rates, including dehiscence, infection, and scar formation. The critical parameter is not the absorption timeline but the strength retention profile — how long the suture maintains load-bearing capacity in tissue.
| Tissue Type | Healing Rate | Support Needed | Key Considerations |
|---|---|---|---|
| Soft tissue / muscle | Moderate (2-4 weeks) | Medium-term absorbable | Low tension, moderate strength needed |
| Fascia / aponeurosis | Slow (4-6 weeks) | Long-term absorbable | High tension, extended strength retention required |
| Skin (percutaneous) | Fast (7-14 days) | Short-term or non-absorbable (removed) | Cosmesis important; suture marks if left too long |
| Oral mucosa | Fast (5-10 days) | Fast-absorbing | Moist environment accelerates absorption |
| Vascular / anastomosis | Permanent requirement | Non-absorbable (permanent) | Hemodynamic stress; no intrinsic strength regained |
| Tendon / ligament | Very slow (3-6 months) | Long-term absorbable or non-absorbable | High mechanical load; prolonged support needed |
Choose Between Absorbable and Non-Absorbable
Use Absorbable When:
- +Internal tissues where removal is impractical
- +Pediatric patients (avoids traumatic removal)
- +Oral mucosa and perineal repairs
- +Subcuticular skin closure
- +Pediatric cardiovascular (allows growth)
- +Any layer where temporary support suffices
Use Non-Absorbable When:
- +Cardiovascular anastomoses (permanent stress)
- +Sternal closure after median sternotomy
- +Tendon repair requiring permanent fixation
- +Hernia mesh fixation
- +External skin closure (will be removed)
- +Any structure requiring lifelong mechanical support
Absorption Timeline Comparison
| Category | Duration | Products | Best For |
|---|---|---|---|
| Rapid absorption | 7-10 days | DesmoNex Rapid, DesmoCryl Rapid | Superficial closure, episiotomy |
| Medium-term | 28-35 days | DesmoNex, Absorbex, DesmoCryl | General surgery, soft tissue |
| Long-term | 90-180 days | DesmoCapro, DesmoPol | Cardiovascular (pediatric), orthopedic |
| Permanent | N/A | DesmoMid, DesmoSilk, DesmoSter | Cardiovascular, sternal closure |
Select Filament Structure
The filament structure — braided (multifilament) or monofilament — affects handling characteristics, knot security, infection resistance, and tissue passage. Neither is universally superior; the optimal choice depends on the clinical context.
| Property | Braided | Monofilament |
|---|---|---|
| Handling | Excellent — soft, pliable | Good — stiffer, more memory |
| Knot security | High — fewer throws needed | Lower — requires extra throws |
| Infection risk | Higher — wicking along strand | Lower — no capillarity |
| Tissue passage | More drag (mitigated by coating) | Smooth, minimal drag |
| Preferred use | General surgery, clean wounds | Vascular, contaminated, subcuticular |
| Desmo Care products | DesmoNex, Absorbex, DesmoSilk | DesmoPol, DesmoCryl, DesmoMid |
Consider Tensile Strength Requirements
Tensile strength retention is the percentage of original breaking strength maintained over time in tissue. The suture must retain sufficient strength until the tissue heals enough to bear load independently. Review the strength retention profiles of Desmo Care products relative to your target healing timeline.
| Product | 2-Week Retention | 3-Week Retention | 6-Week Retention |
|---|---|---|---|
| DesmoNex Rapid | <10% | 0% | 0% |
| DesmoNex | ~75% | ~40% | 0% |
| Absorbex | ~80% | ~45% | 0% |
| DesmoCryl | ~75% | ~50% | ~10% |
| DesmoPol | ~80% | ~70% | ~50% |
| DesmoCapro | ~95% | ~90% | ~80% |
| DesmoMid / DesmoSter | 100% | 100% | 100% |
Evaluate Special Requirements
Coating Technology
Coated sutures reduce tissue drag and improve handling. Desmo Care uses two coating systems: polycaprolactone (PCL) coatings on absorbable products for smooth tissue passage and reduced inflammation, and calcium stearate coatings on braided PGA sutures (DesmoNex, Absorbex) for lubrication without compromising knot security. Choose coated sutures when smooth passage through delicate tissue is required.
Color Selection
Violet sutures provide high visibility in the wound field and are ideal when precise suture placement confirmation is needed. Undyed sutures are preferred for subcuticular skin closure and any application where suture visibility through skin would be cosmetically unacceptable. Most Desmo Care products are available in both violet and undyed versions.
USP Sizing
Select the smallest USP size that provides adequate wound support for the tissue and tension level. General guidelines: size 0-2 for fascial closure; 2-0 to 3-0 for general soft tissue; 3-0 to 4-0 for skin; 4-0 to 6-0 for fine/cosmetic work; 6-0 to 10-0 for ophthalmic and microvascular procedures. Desmo Care sutures are available from USP 10-0 through USP 2.
Needle Selection
Needle choice affects tissue trauma and access. Tapered (round-body) needles are used for soft, easily penetrated tissue (bowel, fascia, blood vessels) — they push tissue aside without cutting. Cutting needles are used for tough tissue (skin, ligaments, tendons). Reverse-cutting needles are the standard for skin closure. Needle length and curve (1/4, 3/8, 1/2, 5/8 circle) are selected based on wound depth and access.

Frequently Asked Questions
What is the most commonly used surgical suture?
Polyglycolic acid (PGA) braided sutures are among the most widely used in general surgery due to their excellent tensile strength, predictable 28-35 day tissue support, and reliable absorption profile. Products like DesmoNex (PGA) and Absorbex (coated PGA) are used for fascial closure, bowel anastomosis, and soft tissue approximation across most surgical specialties. For cardiovascular surgery, polypropylene monofilament (DesmoMid) is the standard.
How do I choose between braided and monofilament sutures?
Choose braided sutures when handling ease and knot security are priorities — they require fewer throws and have a natural 'feel' that most surgeons prefer. Choose monofilament sutures when infection resistance is critical (contaminated wounds, vascular surgery) or when smooth tissue passage is needed (subcuticular closure, cardiovascular). Monofilament sutures also have lower capillarity, meaning they do not wick bacteria along the strand. The trade-off is that monofilament sutures have more memory and require additional throws for knot security.
What suture size should I use?
Suture size selection follows the principle of using the smallest diameter that provides adequate wound support. As a general guideline: 0 to 2 for fascial and abdominal wall closure; 2-0 to 3-0 for general soft tissue and subcutaneous closure; 3-0 to 4-0 for skin closure; 4-0 to 6-0 for pediatric and cosmetic procedures; 6-0 to 8-0 for ophthalmic and microvascular work. High-tension closures (orthopedic, cardiovascular) may require larger sizes. Always consult the product IFU for procedure-specific recommendations.
Can I mix suture types in the same procedure?
Yes — using different suture types for different tissue layers in the same procedure is standard practice and often optimal. A typical abdominal procedure might use absorbable PGA for fascial closure, absorbable PDO for subcutaneous tissue, and either absorbable or non-absorbable sutures for skin. The key is to match each suture to the specific requirements of each tissue layer: strength needed, healing timeline, infection risk, and whether suture removal is practical.
