【导读】:设计者最早是用 DePuy 的跟骨锁定钢板超适应症使用固定粉碎性髌骨骨折,取得良好效果,但术中塑形较困难,基于此设计出冰晶形髌骨锁定钢板。

Saura-Sanchez reported about his good clinical results using the Locking Calcaneal Plate from DePuy Synthes in an off-label manner for comminuted patella fractures. His fixation concept was to place the calcaneal plate on the anterior surface of the reduced patella and to bend plate arms around the distal patella pole for the insertion of longitudinal locking screws from distal to proximal. In a subsequent step, the patella fracture could be fixed with locking screws from anterior to posterior. Although this fixation concept resulted in stable osteosynthesis, there were usability challenges: the plate required frequent cutting and cumbersome bending to adapt the flat plate to the shape of the patella. Furthermore, the intended bending directions could often not be achieved without cutting selected plate arms compromising construct strength. To address these issues Saura-Sanchez envisioned a dedicated, preformed anterior patella plate mimicking the structure of an ice crystal with well distributed locking hole options. I


设计者最早是用 DePuy 的跟骨锁定钢板超适应症使用固定粉碎性髌骨骨折,取得良好效果,但术中塑形较困难,基于此设计出冰晶形髌骨锁定钢板。

From a biomechanical perspective, anterior locked plating of both simple and complex patella fractures provides superior construct stability vs tension band wiring.从生物力学角度看,无论是简单髌骨骨折还是复杂骨折,髌前锁定钢板固定的结构稳定性优于张力带。

估计锁定钢板固定髌骨骨折将是一种不错的选择。
