ABSTRACT
PURPOSE:
To evaluate the tensile strength and repair-site profile of a technique of resorbable barbed suture tenorrhaphy.METHODS:
Forty-eight flexor digitorum profundus tendons were collected from the 8 adult cadavers. In the test group, the tendons were sutured using absorbent 2-0 barb knotless sutures in a 2-strand or 4-strand zig-zag pattern. In the control group, 2-0 Prolene and 3-0 polydioxanone (PDS) were used to suture the tendons using the 2-stand Modified Kessler method and the 4-strand cruciate suture method. Using a tensile force measurement machine, the breaking load (N) and the stiffness (N/mm) were measured. The types of rupture were categorized into suture breaking, knot rupture, and pullout.RESULTS:
In the comparative analysis between the absorbent 2-0 Quill (Angiotech Pharmaceuticals, Canada) suture that used the 2-strand core suture and the 3-0 PDS and 2-0 Prolene sutures, the average breaking load for the 2-0 Quill suture was 26.83±7.47 N, and 21.96±6.78 N and 17.20±4.93 N for the 2-0 Prolene and 3-0 PDS sutures. In the comparison using the 4-strand core suture, the average breaking load for the 2-0 Quill suture was 62.50±13.34 N, and 22.35±5.72 N and 18.67±4.27 N for the 2-0 prolene and 3-0 PDS sutures. The most common type of rupture were knot rupture.CONCLUSION:
For flexor tendon sutures using the absorbent barb sutures, compared to the conventional 2-0 Prolene or 3-0 PDS sutures, absorbent barbed sutures have a higher tensile strength.
