Biomechanical investigation on tendon sutures

Deutsche Flagge: "Für die deutsche Version bitte hier klicken."

We are examining various tendon suture techniques with regard to their biomechanical stability.

 

Tendon tears are very common injuries in trauma surgery. Particularly in the area of the hand and forearm, high suture stability is crucial for early physiotherapeutic treatment in order to achieve the best possible function of the hand. 

To investigate different suture techniques, animal tendons are severed, then sutured using a technique intended for clinical appliance and subjected to a biomechanical stability test in a material testing machine afterwards. For this purpose, the tendon ends are fixated by clamps and tensile forces are applied that simulate the movements of individual fingers. This allows different techniques to be analyzed for differences in stability and tear-out behavior.

A porcine tendon is shown with the severed end fixed using a core and ring suture technique (left). Different suture techniques are tested for differences under tensile loads in a material testing machine (right).
