Needles:
Suture material:
absorbable –
| • | gut: highest tissue reaction, least strength |
| • | dexon, vicryl, maxon, PDS - seem about equivalent: 18 to 30 days of “wound security”, 90 to 180 days = time to “completely absorb” |
| • | boards favorite – longest to “completely absorb” = polydioxanone (PDS) 180 days (though only has 50% tensile strength at 4 weeks) |
non-absorbable –
