Monteggia fractures represent complex injuries requiring careful assessment and surgical intervention. This case report presents a rare variation of a Bado type I Monteggia fracture-dislocation that resembles features from the Jupiter subclassification type IID. A 39-year-old male sustained a high-energy injury while riding an all-terrain vehicle, resulting in a proximal segmental ulnar shaft fracture with anterior radial head dislocation. Open reduction and internal fixation (ORIF) of the ulna using a pre-contoured proximal ulna low-contact dynamic compression plate (LC-DCP) successfully restored alignment, leading to spontaneous reduction of the radial head. The postoperative course was uneventful, with satisfactory healing and functional recovery. This case underscores the importance of meticulous ulnar reconstruction in Monteggia fracture-dislocations and contributes to the limited literature on anterior radial head dislocation patterns.
孟氏骨折是复杂损伤，需要仔细评估和手术干预。本病例报告展示了一种罕见的巴多I型孟氏骨折脱位变异，类似于朱庇特分类法中的IID型特征。一名39岁男性在骑全地形车时遭受高能损伤，导致尺骨近端节段性骨折并伴有桡骨头前脱位。使用预塑形的近端尺骨低接触动力加压钢板（LC-DCP）对尺骨进行切开复位内固定（ORIF）成功恢复了对线，使桡骨头自行复位。术后过程顺利，愈合和功能恢复良好。本病例强调了在孟氏骨折脱位中进行细致尺骨重建的重要性，并为关于桡骨头前脱位模式的有限文献做出了贡献。
