To determine the frequency of angular malalignment of femur in patients undergoing Intra Medullary nailing for femur shaft fracture by measuring axis on immediate postoperative plain radiographs.
A cross-sectional study was conducted at the Section of Orthopaedics, Department of Surgery, Aga Khan University Hospital, Karachi from 1st January 2019 till 30th June 2019. All patients between the ages of 15 to 80 years who underwent IM nailing for femur shaft fractures were included. Angulation was measured on immediate post-operative X-ray films and an angle of ≥5° on AP and/or lateral views was defined as malalignment.
A total of 65 patients were enrolled in the study with a mean age of 39.9 ± 16.5 years. Majority of the patients,49 (75.4) were males and road traffic accidents were found to be the most common mechanism of injury. Malalignment after surgery was encountered in 6(9.2%) patients. Proximal femur fractures were noted to be significantly associated with malalignment with a p-value of 0.014.
This shows that frequency rate of malalignment after IM nail for femoral shaft fractures in a developing country like Pakistan is comparable to internationally reported literature and proximal femur fracture is a risk factor for malalignment.
通过测量术后即刻的 X 线片上的股骨轴，确定接受髓内钉治疗股骨干骨折患者的股骨对线不良的频率。
这是一项 2019 年 1 月 1 日至 2019 年 6 月 30 日在卡拉奇 Aga Khan 大学医院骨科进行的横断面研究。所有年龄在 15 至 80 岁之间接受 IM 钉治疗股骨干骨折的患者均纳入研究。在术后即刻 X 射线片上测量角度，将 AP 和/或侧位上的角度≥5°定义为对线不良。
共有 65 名患者入组研究，平均年龄为 39.9±16.5 岁。大多数患者（49 例，75.4%）为男性，道路交通伤害被认为是最常见的损伤机制。术后发生对线不良的患者有 6 例（9.2%）。股骨近端骨折与对线不良显著相关，p 值为 0.014。
这表明在巴基斯坦等发展中国家，接受 IM 钉治疗股骨干骨折后对线不良的频率与国际报道的文献相当，股骨近端骨折是对线不良的一个危险因素。
