Load Tests

In a pig bone model mimicking the human trapezium, we assessed the cementless fixation of trapezial cups in cancellous and cortical bone. Thirty-two saddle-shaped pig forefoot bones were prepared for cup fixation. Conical Konos cups (Beznoska, Kladno, Czech Republic) size 9 mm or 10 mm diameter were impacted. Cup migration was evaluated with repeated radiostereometry after intervals of cyclic-load tests. Migration increased for every load-interval up to 750 N and was higher with cancellous bone fixation than with cortical bone fixation. In cancellous bone, 9 mm cups migrated more than 10 mm cups. At the highest load (1050 N), the cumulative implant survival was 88% for 10 mm cups with cortical bone fixation and 13% for 9 mm cups with cancellous bone fixation. We conclude that mechanical fixation of conical Konos cups was better in cortical than in cancellous bone. Our results further suggest that the largest possible cup diameter should be used.

The purpose of this study is to assess how the insertion angle influence the stability mini-implant when loaded with 200cNe in this study, 2mini-screws were implanted in male rabbits’ (n=25) tibia in a 6weeks interval between the firstone and the second one. The second mini-implants were placed at different angles with respect to the cortical bone: -20° in the direction of the force e (GroupI), perpendicular to the force (GroupII) and 30° in the opposite direction of the force (GroupIII). These experimental implants were immediately loaded (right tibias). The Tad`s on the left tibias were regarded as control. The animals were sacrificed six weeks after the first surgery. Linear distances between the two Tad`s were measured with a digital caliper at the time of placement, and after the sacrifice, then were compared. The displacements were: GroupI, 2.96mm ±1.05; GroupII, 0.27mm ±0.36; and GroupIII, 0.29 mm ±0.26. The controls remained. The values for the micro-implants of GroupI showed statistically significant differences (p≤0.05) compared to GroupsII y III. Based on these data, we can conclude that mini-implants inclined towards the direction of the force applied induce more displacement than the ones placed perpendicular to theforce or in the opposite direction of the force
