The aim of this retrospective study was to investigate the suitability of bi-columnar internal fixation through a combined medial and lateral approach for the treatment of intra-articular distal humerus fractures.
Nineteen cases of intra-articular distal humerus fractures were treated with open reduction and bi-columnar internal fixation through a combined medial and lateral approach. The reduction in the articular surface and functional recovery of the affected elbows was assessed at an average follow-up of 15.8 ± 7.9 (7-43) months.
The gap in the main articular fragments was less than 1 mm in 16 cases, while a gap of more than 1 mm and less than 2 mm was identified in 2 cases and of 3.7 mm in one case. All the fractures were united. At the latest follow-up, the mean flexion-extension of the elbows was 113.4° ± 20.7°, while the pronation-supination of the forearms was 158.3° ± 8.5°, and the mean Mayo Elbow Performance Index was 93.7 ± 9.1 points, leading to 13 excellent outcomes, and 6 with good results.
Intra-articular fractures of the distal humerus can be effectively treated by open reduction and internal fixation through a combined medial and lateral approach at the elbow.
本回顾性研究旨在探讨经内外侧联合入路双柱内固定治疗肱骨远端关节内骨折的适用性。
19例肱骨远端关节内骨折患者采用经内外侧联合入路切开复位双柱内固定治疗。平均随访15.8±7.9（7 - 43）个月，评估关节面复位情况及患侧肘关节功能恢复情况。
16例主要关节碎片间隙小于1mm，2例间隙大于1mm且小于2mm，1例间隙为3.7mm。所有骨折均愈合。末次随访时，肘关节平均屈伸角度为113.4°±20.7°，前臂旋前旋后角度为158.3°±8.5°，Mayo肘关节功能评分平均为93.7±9.1分，优13例，良6例。
经肘关节内外侧联合入路切开复位内固定可有效治疗肱骨远端关节内骨折。
