 The presence of pamidronate during local use of bisphosphonates (BP)-enriched bone cement was determined. The question was whether pamidronate implanted into the bone cement is eluted. The study was performed on 10 probes of BP-enriched bone cement located in 0.9% NaCl. The probes were incubated for 3 and 6 weeks. Ion-pair HPLC was used for the detection of pamidronate. Then, capillary electrophoresis was applied for quantitative analysis of pamidronate in the 3rd and 6th week after incubation. The presence of pamidronate, eluted from BP-enriched bone cement into 0.9% NaCl solution 3 and 6 weeks after incubation, was demonstrated. These results may explain the changes in the level of cytokine RANKL and bone turnover marker osteoprotegrin in rats’ serum treated with BP-enriched bone cement 3 and 6 weeks after surgery. The possibility of effective local use of BP-enriched bone cement in veterinary medicine was underlined. The results, and the former conducted research, point out that the clinical applications of BP-enriched bone cement in vivo may have some validity in the future.
