ANTIBIOTIC-IMPREGNATED ALLOGRAFT: MICROBIOLOGICAL COMPARATIVE ANALYSIS

Karaganda State Medical University, Karaganda,
The Republic of Kazakhstan

Objective. To develop a method of the femoral head allograft impregnation, prepared according to the Marburg system of the bone bank, with antibiotics.
Methods. In the experiment the allografts of the femoral heads, prepared according to the Marburg system of the bone bank, were impregnated with gentamicin. Four groups were formed depending on the impregnation parameter. In the I and II groups, a whole femoral head was used, in the III and IV perforated. In groups I and III, antibiotic impregnation was carried out simultaneously with the heat-treated femoral head and groups II and IV after heat treatment. In the control group, the whole bone allograft was subjected to standard heat treatment without its impregnation with antibiotic. From each group, 4 bone fragments were cut from a certain level of depth (cortical, subcortical, and central). The antibiotic release was evaluated by agar diffusion test against S. aureus after 24 hours.
Results. The obtained results of the study indicate the presence of antimicrobial activity in all groups except the control group. However, in the II and IV group, the inhibition zone was higher compared with the I and III groups (p <0.05). The antimicrobial activity of gentamicin in the groups where heat treatment was carried out together with the antibiotic (I, III groups) was lower than in the groups by soaking the allografts in solution with the antibiotic (II, IV groups) (p <0.05). In the control, group V, continuous growth of S. aureus was observed.
Conclusions. Allograft impregnated with antibiotic, prepared according to the Marburg system of the bone bank, provides the inhibition of growth of Staphylococcus aureusin vitro. Perforation of bone allograft according to the developed method allows increasing the antibiotic soaking on average by 10%.
