To assess the outcome after using the Shaft-Condylar angle (SCA) as intraoperative reference for sagittal plane correction in displaced lateral humeral condyle fractures in children presented 3-weeks after injury.
Ten children, with delayed presentation of a displaced lateral humeral condyle fracture and undergoing surgery during 1999-2011, were reviewed. The goal was to obtain a smooth articular surface with an intraoperative SCA of nearly 40° and nearest-anatomical carrying angle. They were allocated into two groups according to the postoperative SCA [Good-reduction group (SCA=30-50°), and Bad-reduction group (SCA<30°, >50°)] and the final outcomes were then compared.
All fractures united without avascular necrosis. The Good-reduction group (n=7) showed a significant improvement in final range of motion and functional outcome compared to the Bad-reduction group (n=3) (p=0.02). However, there was no significant difference in pain, carrying angle and overall outcome between both groups.
SCA is a possible intraoperative reference for sagittal alignment correction in late presented displaced lateral humeral condyle fractures.
评估在受伤3周后出现的儿童肱骨外侧髁移位骨折中，使用髁干角（SCA）作为矢状面矫正术中参考指标的术后效果。
回顾了1999年至2011年间10例肱骨外侧髁移位骨折延迟就诊并接受手术的儿童病例。目标是通过术中使SCA接近40°并获得最接近解剖提携角来获得光滑的关节面。根据术后SCA将他们分为两组[良好复位组（SCA = 30 - 50°）和不良复位组（SCA < 30°，> 50°）]，然后比较最终结果。
所有骨折均愈合，无缺血性坏死。与不良复位组（n = 3）相比，良好复位组（n = 7）在最终活动范围和功能结果方面有显著改善（p = 0.02）。然而，两组在疼痛、提携角和总体结果方面无显著差异。
SCA可能是延迟出现的肱骨外侧髁移位骨折矢状面排列矫正的术中参考指标。
