Wagner FC, Jaeger M, Friebis C, et al. - In this study, posterior plating was compared with collateral double plating for osteosynthesis of unstable osteoporotic fractures. Researchers created a comminuted displaced Mayo type II B fracture in 8 osteoporotic pairs of fresh-frozen human cadaver elbows. They conducted biomechanical testing as a pulling force to the triceps tendon in 90° of elbow flexion. They used cyclical changes between 10 and 300 N at 4 Hz for 50,000 cycles. The results of this study indicated that the angular stable double plating exhibited comparable biomechanical stability compared to posterior plating of unstable osteoporotic olecranon fractures under high cycle loading conditions. As per the results, failure due to bony triceps avulsion following DP needs future clinical and biomechanical evaluation e.g. on suture augmentation or different screw configurations.
