Evaluation of Parameters Determining the Pull-Out Strength of Poly(L-Lactide-Co-ε-Caprolactone) Barbed Suspension Threads: A Comparative ex vivo Study.

PURPOSE: This study aimed to examine a pull-out strength test methodology and compare the pull-out strength of different insertion methods for poly(L-lactide-co-ε-caprolactone) (PLCL) barbed suspension threads.

METHODS

A custom-designed "pull-out strength test device" was used to measure the maximum force required to pull out threads inserted into an ex vivo turkey breast model.

RESULTS

Insertion techniques influence pull-out strength. Additionally, trend analysis indicated that thinner needles (0.85 mm) generally yielded higher pull-out resistance than larger diameter needles (1.28 mm), suggesting they may create a tighter initial grip within the tissue.

CONCLUSION

Different insertion techniques influence the pull-out strength of PLCL in an ex vivo model.
