Abstract
Sixty-four dog cadaver flexor digitorum profundus tendons in zone 2 were lacerated and repaired with a simple or a cross-stitch peripheral circumferential suture in combination with two-, four-, or six-strand core sutures. The tensile and gap strengths were compared. The range of tensile strengths with the cross-stitch circumferential suture in combination with various core suture techniques (4.28–9.37 kgf) was significantly higher than the range of values for the simple circumferential suture and similar core suture techniques (1.70–4.98kgf). The tensile strength with two-strand core suture plus the cross-stitch circumferential suture (5.29kgf) was as great as that of the six-strand core suture plus the simple circumferential suture (4.98kgf). Increased gap strength values were also observed with the cross-stitch (1.11–3.19 kgf) compared to the simple (0.84 to 1.76 kgf) circumferential sutures. The cross-stitch circumferential suture had a mechanical advantage in flexor tendon repair compared to the simple circumferential suture.
