Tensile strength of explant. An incisional hernia defect was created in the rabbit abdomen. Three weeks following the primary surgery, the defect in each rabbit was repaired with HADM or PADM. Tensile strength of the implants was determined at 4 and 20 weeks later using an MTS 858 Mini Bionix. All values are mean ± SEM (n = 4). The results shown with PADM at the 20 week time point were from the two intact implants (mean ± range of error, n = 2). HADM, human acellular dermal matrices; PADM, porcine acellular dermal matrices. The tensile data from the pre-implant phase (time zero) was taken from earlier testing by the identical test protocol and from a larger, multi-donor sample
