Data from cyclic tensile tests on sutured organs to evaluate creep behaviour, distraction, and residual thread strength.
Abstract: A number of applications in the surgical practice are based on tensile sutures aimed to keep soft tissues in place and compensate the exit of neuropathies, prolapses or general tissue relaxation. Long-term behaviour of these constructs need to be carefully examined in order to define tensile forces to be applied and to compare different suture anchors. Data here reported refer to equine laryngoplasties, where a suitable loading system has been designed in order to be able to test sutures in-sito, applying known forces ("On-site testing of sutured organs: an experimental set up to cyclically tighten sutures" (Pascoletti et al., 2020 [1])). The loading protocol was made of two steps: in the first step, 3000 loading cycles have been performed; in the following step, a tensile test up to rupture was performed. Cyclic load/displacement curves allow evaluating suture distraction, as a consequence of suture migration and/or soft tissues creep. Tensile curves allow evaluating the residual thread strength and its ultimate displacement. These data can provide a detailed insight of long-term suture behaviour and can be a reference to compare different threads and/or suture anchors.

This research article presents a tensile testing study to assess the long-term behavior of sutures used in surgery, focusing on their performance under strain and the residual strength of a suture thread after use.
Research Objectives
- The study aims to investigate the role of sutures used in surgical procedures, particularly their ability to secure soft tissues in place and address health issues such as neuropathies, prolapses, or general tissue relaxation.
- The researchers wanted to study the long-term performance of these sutures, specifically measuring the tensile forces applied and comparing different types of suture anchors.
- Particularly significant is that the research was focused on equine laryngoplasties, i.e., surgical procedures performed on the larynx or voice box of horses.
Methodology
- A specially designed loading system was used for conducting in-situ tests on sutures. This system applied known forces to the sutures during testing.
- The testing protocol included two distinct steps: The first step involved applying 3000 loading cycles to the sutures; the second step was a tensile test up to the point of rupture.
- The study used cyclic load/displacement curves to evaluate the suture distraction, which can occur due to the movement of the suture or the creep of the soft tissues.
Findings
- Tensile testing curves were used to evaluate the residual strength of the suture thread and its ultimate displacement. The residual strength is a measure of the thread’s remaining strength after the tensile forces have been applied, and the ultimate displacement is the maximum movement observed in the thread before breaking.
- The results provided valuable insights into the long-term behavior of sutures and served as a reference for comparing different types of threads and suture anchors.
- The findings of this research could be beneficial for surgeons and medical practitioners to understand the reliability and performance of sutures, enabling them to make informed decisions about their use in surgical procedures.
