UNASSIGNED: The characteristics and treatment methods of transverse and comminuted DHMDJ fractures in children were summarized and analyzed by referring to relevant literature at home and abroad.
UNASSIGNED: DHMDJ fractures in children are not uncommon clinically, with high fracture line position, multi-directional instability, difficult closed reduction in treatment, and easy to cause complications such as coronal and sagittal deformity of the elbow. The Kirschner wire technique was effective for DHMDJ fractures with the fracture line at the middle and low levels, but was prone to iatrogenic ulnar nerve injury. Elastic stable intramedullary nail is suitable for higher-position transverse DHMDJ fractures. However, this technique requires a second operation to remove the internal fixator, and may cause iatrogenic epiphysis plate injury in children. External fixator is a new way to treat DHMDJ fractures, and it can show satisfactory results for transverse and comminuted DHMDJ fractures. However, at present, there are few relevant studies, and most of them focus on biomechanical studies, and the efficacy lacks high-quality clinical research support.
UNASSIGNED: The ultimate goal of DHMDJ fracture treatment in children is to restore the anatomical alignment of the fracture and prevent the loss of reduction. The choice of internal fixator depends on the location of the fracture line and the shape of the fracture to provide personalized treatment.
UNASSIGNED: 总结儿童肱骨远端骨干-干骺端交界区(distal humeral metaphyseal-diaphyseal junction,DHMDJ)骨折治疗研究进展,为临床提供参考。.
UNASSIGNED: 广泛查阅国内外有关文献,对儿童DHMDJ横形骨折及内侧柱不稳定骨折特点及相关治疗方法进行总结分析。.
UNASSIGNED: 儿童DHMDJ骨折在临床并不少见,其骨折线位置较高,往往具有多方向不稳定性,治疗上闭合复位困难,容易引起肘关节冠状面和矢状面畸形等并发症。以往克氏针技术对于中、低位骨折疗效较好,但容易引起医源性尺神经损伤。弹性髓内钉适用于骨折线位置较高的横形骨折,然而需要二次手术取出内固定物,还可能导致医源性骺板损伤。外固定架是治疗DHMDJ骨折新方式,无论是横形骨折,还是内侧柱不稳定骨折,临床疗效均满意。然而,目前相关研究较少,多集中于生物力学研究,疗效缺少高质量临床研究支持。.
UNASSIGNED: 儿童DHMDJ骨折治疗以恢复骨折解剖对位和防止复位丢失为最终目的,内固定物选择取决于骨折线位置和骨折形态。.
