The supra-condylar humeral fractures are commonest fractures at the elbow in children and represent a third of all limb fractures in children under the age of 7 years. These fractures are associated with neurological deficit and any of the three long nerves of upper arm can be involved in these fractures. This study was conducted to determine the frequency of median nerve injury in children aged 2-11 years presenting with closed supracondylar fracture of humerus.
This descriptive cross-sectional study was conducted at the department of orthopaedics and trauma, Ayub Teaching Hospital Abbottabad from July 2016 to June 2018. One hundred and seventy-one patients with supracondylar fracture of humerus were enrolled. They were treated as per department protocols and the outcome in terms of neurological damage was noted for each study participant.
The frequency of neurological damage was 21.05% with median nerve affected most commonly (13.45%). A statistically strong association was found between damage to median nerve and type of fracture, arm involvement and sex of patients (p<0.05) while no statistically significant association with age was obtained.
Neurological damage is a common complication of supracondylar humeral fractures with median nerve being the most commonly affected nerve in these fractures.
肱骨髁上骨折是儿童肘部最常见的骨折，占7岁以下儿童所有四肢骨折的三分之一。这些骨折与神经功能缺损有关，上臂的三条长神经中的任何一条都可能累及这些骨折。本研究旨在确定2至11岁肱骨髁上闭合性骨折患儿正中神经损伤的发生率。
本描述性横断面研究于2016年7月至2018年6月在阿伯塔巴德阿尤布教学医院骨科与创伤科进行。纳入171例肱骨髁上骨折患者。他们按照科室方案接受治疗，并记录每位研究参与者的神经损伤情况。
神经损伤发生率为21.05%，其中正中神经受影响最常见（13.45%）。正中神经损伤与骨折类型、患侧手臂及患者性别之间存在统计学上的强关联（p<0.05），而与年龄无统计学显著关联。
神经损伤是肱骨髁上骨折的常见并发症，正中神经是这些骨折中最常受影响的神经。
