Mechanical Strengths of Tendon SuturesAn in vitro comparative study of six techniquesFrom the Upper Limb and Hand Surgery Unit and the Bioengineering Laboratory, Department of Orthopaedics and Trauma Surgery, Ribeirão Preto School of Medicine, University of São Paulo, Brazil Correspondence: C. Barbieri MD, Department of Orthopaedics and Trauma Surgery, Ribeirão Preto School of Medicine, 14048–900 Ribeirão Preto SP, Brazil. A comparative study of six tendon suturing techniques (1. Modified Kessler + simple epitendinous running suture; 2. Modified Kessler + Halsted epitendinous suture; 3. "Six strand" suture; 4. "Interlocking" suture; 5. "Cross stitch" suture; 6. simple epitendinous running suture) was carried out by evaluating strength in relation to the beginning of separation between the tendon stumps, a 3 mm separation and rupture in porcine flexor tendons. The technique most resistant to initial separation was the modified Kessler + Halsted epitendinous suture followed by the "Six strand" suture. The "Six strand" suture was the most resistant to the 3 mm separation and rupture followed by the modified Kessler + Halsted epitendinous suture. Despite the greater resistance to rupture of the "Six strand" technique, we conclude that modified Kessler + Halsted epitendinous suture showed the best overall performance and was easier to use.
