Biomechanical evaluation of the Pulvertaft versus the 'wrap around' tendon suture technique
The purpose of this study was to compare the biomechanical properties of a novel wrap around tendon repair method with those of the standard Pulvertaft technique used for tendon reconstructions. Seventy-two porcine extensor tendons were used to create 36 reconstructions in six sets of six repairs, each using one of the two surgical techniques with differing lengths of the reconstructions. All the reconstructions were tested in vitro by cyclic tensile loading, resulting in the time-zero strength. When only the size of the repair and the strength were compared, and length of the reconstruction was not taken in consideration, the 'wrap around' reconstructions were of similar strength but less bulky than the Pulvertaft repairs. In conclusion, the 'wrap around' technique gives a thinner reconstruction which is as strong as, or stronger than the Pulvertaft technique, depending on the amount of weaves.
