Objective
This study aims to observe whether Kryptonite Bone Cement combined with a standard Kirschner wire, instead of autogenous bone grafts, increases bone healing and mechanical strength in rats with tibia fractures.
Methods
The study included sixteen rats, which were divided into two groups as a control group (n=8) and an experimental group (n=8). After segmental fractures were made in both groups, intramedullary fixation of tibia procedures were conducted with the use of a Kirschner wire. No additional procedures were performed in the control group, but Kryptonite Bone Cement was applied in the experimental group. The rats were evaluated clinically, radiologically and histologically 4 times; immediately after the operation, and at the 1st, 3rd, and 6th weeks following surgery.
Results
One rat from the experimental and one from the control group had both wound dehiscence and wound site infection. No recovery was observed in any rats either in the control or experimental group immediately after surgery. During week 1, callus formation was identified in 5 rats in the experimental group (p=0.0072), and during week 3, fracture lines disappeared in 4 rats in the experimental group (p=0.064); the differences between control and experimental groups were statistically significant. During week 6, no statistical significance was observed in radiological assessments for the control group and experimental group (p=0.71).
The rate of non-union was higher in the control group (37.50%) than in the experimental one, while the rate of complete fusion was higher in the experimental group (87.50%) than that in the control group.
Conclusion
Osteoconductivity and ergonomic qualities of Kryptonite Bone Cement prove helpful in bone repair. Future studies to be conducted in a prospective and randomized manner will be effective on demonstrating the effectiveness of Kryptonite Bone Cement.
