Background. Infection of percutaneous implants in patients with limb amputation is the most common complication. This study aimed to evaluate the microbiological contamination of the implantation zone depending on the implant mechanical compression under the conditions of the additional external fixation. Methods. The study was performed on 36 male rabbits. The tibia of all the rabbits was sawn at the border of the upper and middle parts. The medullary canal was reamed and a percutaneous implant was placed in the tibial stump. The segment and the implant were fixed with an Ilizarov apparatus. An additional compression device was installed in 30 animals. We used 5 compression modes, accordingly, 6 experimental groups were formed, 6 animals in each: group 1 — without compression, group 2 — compression on the implant with force of 0.053 N/mm2, group 3 — compression on the implant with force of 0.105 N/mm2, group 4 — compression on the implant with force of 0.158 N/mm2, group 5 — compression on the implant with force of 0.211 N/mm2, group 6 — compression on the implant with force of 0.263 N/mm2. The restraint was removed 6 weeks after implantation for a total follow-up of 26 weeks. The microflora of the place where the implant enters the skin (the implant / skin interface) was investigated, the level of blood leukocytes and the level of C-reactive protein in blood serum were determined. Results. On days 9-10 after implantation, significant differences in the microbial landscape were found at the site of the exit of the metal implant in animals of different groups. The largest number of strains was found in animals of groups 1, 5 and 6, the smallest in groups 2 and 3. The most frequently detected strains: S. saprophyticus and Enterococcus spp. It was found that the greatest statistically significant increase in the level of CRP in the blood serum was observed in animals of group 6. The level of leukocytes in animals of all groups did not change statistically significantly relative to preoperative values. Animals with better osseointegration (groups 2 and 3 — no cases of implant loss) showed a minimal number of growing strains. Conclusions. The microbiological profile of the implantation zone of percutaneous implants changes depending on the amount of mechanical compression. The optimal mode is 0.053-0.105 N/mm2. © 2022, Eco-Vector LLC.
