Abstract

Introduction and hypothesis

The experiment evaluated different lightweights (<32 g/m²) in terms of shrinkage and biomechanics.

Methods

PP-8 (polypropylene of 7.6 g/m²), PP-s (PP-8 with absorbable sheets), PP-32 (PP with absorbable fibers; 32.0 g/m²) and polyvinylidinefluoride (PVDF; 24.9 g/m²) augmented primary sutured repairs of the anterior abdominal wall in a total of 40 rabbits. Rabbits were implanted by only one type of mesh at four abdominal sites. After 7, 14, 30, 60 and 120 days, 2 rabbits were sacrificed per group. Three additional unoperated rabbits were used as controls. Shrinkage and uni-axial tensiometry were evaluated.

Results

PP-s implants wrinkled in 70%. PP-32 did not shrink whereas PP-8 and PVDF shrank by 20%. Explants were as strong as the controls; however, they differed in compliance. At lower stress, the tested materials were equally stiff.

Conclusions

The biomechanical behaviour of the tested lightweights does not mimic that of native controls. Weight reduction does not prevent shrinkage.
