Fragility fractures of the distal humerus in elderly patients, especially the low transcondylar fracture pattern, can be difficult to optimally manage. Although the fractures are typically low energy resulting in either extra-articular or simple intra-articular patterns, gaining fixation into the distal fragments can be difficult with open reduction internal fixation (ORIF) using traditional 90-90 or parallel plating techniques. Anatomy preserving reconstruction with ORIF is preferred over total elbow arthroplasty (TEA) if possible. In this study, 15 patients were managed with a bicolumnar 90-90 plating construct as a novel method of enhancing distal fixation in these fractures. Fourteen patients went on to radiographic union at an average of 77 days after surgery with an average arc of motion of 105°. One patient was lost to follow-up. Bicolumnar 90-90 plating of distal humerus fractures in elderly patients may represent a viable alternative to traditional ORIF or TEA.
老年患者肱骨远端的脆性骨折,尤其是低位髁上骨折类型,可能难以得到最佳治疗。尽管这些骨折通常为低能量损伤,导致关节外或简单关节内骨折类型,但采用传统的90-90或平行钢板技术进行切开复位内固定(ORIF)时,将固定装置置入远端骨折块可能会很困难。如果可能的话,保留解剖结构的ORIF重建优于全肘关节置换术(TEA)。在本研究中,15例患者采用双柱90-90钢板结构作为增强这些骨折远端固定的新方法进行治疗。14例患者术后平均77天达到影像学愈合,平均活动弧度为105°。1例患者失访。老年患者肱骨远端骨折采用双柱90-90钢板固定可能是传统ORIF或TEA的可行替代方案。
