Novel suturing technique, based on physical principles, achieves a breaking point double that obtained by conventional techniques

Figure 1 Theoretical model to reduce tension via an 8-angle suture pattern.

Figure 2 Device to apply a progressively-increasing separation force to the suture surfaces, and to measure the tension exerted until the breaking point is reached.

Figure 3 Steps to create the proposed “double-diabolo” suture. A: We started with a central stitch that was perpendicular to the surfaces to be joined; B: Then we created an X-shaped stitch to the right; C: We returned with a second central stitch; D: We created another X-shaped stitch, this time to the left; E: We finally returned with a third central stitch to complete the “central column”; F: Then the stitch assembly was knotted with the thread that was centrally located at the outset.

Figure 4 Results of the comparative analysis (A and B).
