Background: Barbed suture technology has shown promise in flexor tendon
repairs, as there is an even distribution of load and the need for a knot
is eliminated. We propose that a quick and simple, novel, barbed technique
without any exposed barbs on the tendon surface has comparable
strength and a smaller cross-sectional area at the repair site than traditional
methods of repair.
Methods: Forty porcine flexor tendons were randomized to polybutester
4-strand barbed repair or to 4-strand Adelaide monofilament repair. The
cross-sectional area was measured before and after repair. Biomechanical
testing was carried out and 2-mm gap formation force, ultimate strength of
repair, and method of failure were recorded.
Results: The mean ultimate strength of the barbed repairs was 54.51 ± 17.9
while that of the Adelaide repairs was 53.17 ± 16.35. The mean 2-mm gap
formation force for the barbed group was 44.71 ± 17.86 whereas that of
the Adelaide group was 20.25 ± 4.99. The postrepair percentage change in
cross-sectional area at the repair site for the Adelaide group and barbed
group was 12.0 ± 2.3 and 4.6 ± 2.8, respectively.
Conclusions: We demonstrated that a 4-strand knotless, barbed method
attained comparable strength to that of the traditional Adelaide repair
technique. The barbed method had a significantly reduced cross-sectional
area at the repair site compared with the Adelaide group. The 2-mm gap
formation force was less in the barbed group than the Adelaide group.
Barbed repairs show promise for tendon repairs; this simple method
warrants further study in an animal model. |
