From the Research
For a distal finger laceration, 6-0 non-absorbable suture material is the best choice, as it provides optimal cosmetic results while minimizing scarring and tissue trauma. When selecting a suture size, it's essential to consider the location and thickness of the skin. For lacerations on the dorsal aspect of the finger, where the skin is thinner, 6-0 nylon or polypropylene is recommended 1. In contrast, for the palmar surface, where the skin is thicker, 5-0 suture may be more suitable.
Key Considerations
- Suture size: 6-0 non-absorbable suture material is preferred for distal finger lacerations
- Suture material: Nylon or polypropylene are good options for optimal cosmetic results
- Suture technique: Simple interrupted technique allows for proper wound drainage and minimizes infection risk
- Suture spacing: Maintain a spacing of approximately 2-3mm between each stitch
- Suture removal: Remove sutures after 7-10 days
- Wound care: Thoroughly irrigate the wound with normal saline prior to closure, and remove any foreign bodies or devitalized tissue to prevent infection and promote optimal healing. Some studies suggest that the use of prophylactic antibiotics may not be necessary for simple hand lacerations 2, but this does not directly relate to the choice of suture size. The most recent and highest-quality study on suture materials and techniques is from 2022 1, which provides guidance on selecting the most appropriate suture materials and techniques for hand surgery.
