Here is your educational poster comparing Simple Continuous vs Interlocking Continuous sutures. Here's a summary of what the poster covers, based on authoritative textbook sources:
Simple Continuous (Running) Suture
- An anchor knot is placed at one end; only the free tail is cut, preserving the needle-end
- The needle passes at an oblique angle across the wound repeatedly, forming a helical coil
- Loops are the exposed portions of this coil, tied off at both ends with only 2 knots total
- Tension is distributed evenly along the full length of the wound
- Accommodates mild post-op wound swelling
- Best for thin, lax skin (eyelids, ears, neck, scrotum) and skin graft attachment
- Risk: if one loop breaks, the entire closure can unravel (Roberts & Hedges' Clinical Procedures in Emergency Medicine)
Interlocking Continuous (Running Locking / Lock Stitch) Suture
- Starts identically to simple continuous, but the needle passes through the previous loop before each new bite
- This creates a chain-lock effect that prevents loop slippage during placement
- Stronger than the simple running suture and provides superior hemostasis
- Particularly useful on the scalp and other well-vascularized wounds
- Risk: increased risk of wound-edge necrosis if placed too tightly or if significant post-op swelling occurs (Fitzpatrick's Dermatology)
Key Differentiator
The single defining difference is the interlocking step - passing the needle through the prior loop. This adds strength and hemostasis but reduces the suture's ability to accommodate tissue swelling.
