A biomechanical comparison of multistrand flexor tendon repairs using an in situ testing model

Measurement of the Flexing Force of the Fingers by a Dynamic Splint With a Dynamometer

“…14 We are also aware that mechanical stress in the suture area promotes intrinsic healing of the tendon 15,16 and that more resistant sutures allow active and controlled movement. 17,18 However, we believe that the ideal control of this movement is based on the measurement of the force exerted by the affected motor system (flexor or extensor). The splint developed in this study makes it possible to promote active and controlled movement, by applying a force of a known and progressively greater magnitude.…”

Suture techniques with high breaking strength and low gliding resistance: Experiments in the dog flexor digitorum profundus tendon

“…To achieve a breaking strength which exceeds light grasping and pinching forces, newer suture techniques with increased holding ability, such as the Becker (1978) marginal suture, the double-loop locking suture (Lee 1990), the 6-strand Savage suture (Savage and Risitano 1989), and cruciate repair (McLarney et al 1999, Barrie et al 2000 have been developed. The classic Kessler method has also continued to be modi ed.…”

Flexor tendon repair using a new suture technique: a comparative in vitro biomechanical study

“…To increase tensile strength several multistranded and augmented repairs have been developed. On the one hand, the strength of flexor tendon repair is roughly proportional to the number of sutures strands [13,18,19]. On the other hand multistranded core sutures are in discussion because of problems with tendon gliding, bulking at the repair site and increased tissue handling which can lead to increased adhesions [20].…”

“…On the other hand multistranded core sutures are in discussion because of problems with tendon gliding, bulking at the repair site and increased tissue handling which can lead to increased adhesions [20]. Four-strand repairs are considered most advantageous since they provide adequate tensile strength while minimizing interference with tendon gliding [18,21]. We wished to compare our own four-strand suture techniques with three clinically proven techniques (Kessler, Tsuge, Bunnell) which are all two-strand.…”
