The rising incidence of distal intra-articular humeral fracture in elderly patients associated with osteoporosis frequently leads to difficulties in acute reconstruction and may result in early failure of internal fixation. The biomechanics of the elbow joint and especially the flexor group as well as the brachioradialis muscle as part of the extensor group is analyzed. The complex motion pattern of the transarticular muscle groups increases the load on internal fixation and may affect the interface between implant and osteoporotic bone. An external fixator with motion capacity serves to protect the internal osteosynthesis and secures the fixation in osteoporotic bone.
老年患者中与骨质疏松相关的肱骨远端关节内骨折发病率不断上升，常常导致急性重建困难，并可能导致内固定早期失败。本文分析了肘关节的生物力学，特别是作为伸肌组一部分的屈肌组以及肱桡肌。经关节肌肉群的复杂运动模式增加了内固定的负荷，并可能影响植入物与骨质疏松骨之间的界面。具有运动能力的外固定器有助于保护内固定，并确保在骨质疏松骨中的固定。
