Offset nail fixation of femoral neck fractures improves patient outcomes

A newly designed intramedullary hip nail with the cervical axis offset anterior to the main shaft axis gives improved results. Due to its shape better matching the human anatomy, the offset nail is easier to fix in the centre of the femoral neck and the femoral ball and the fracture bone fragments are aligned closer to their pre-fracture anatomical position at the fracture site. The data is from a clinical trial comparing patients who suffered an intertrochanteric hip fracture. 50 patients received an implant of the new Offset Nail; and 50 control cases received a commercially available non-offset nail. The data includes patient case data, fracture classification, fracture reduction measurements, x-ray images, and rehabilitation results. Patients who received the offset nail rehabilitate in a shorter time, achieve better post-surgery mobility, and are more likely to re-gain the capability for independent living.

本研究针对一款颈轴相对于主杆轴向前偏置的新型髓内髋钉（intramedullary hip nail）展开，该器械可获得更优的临床效果。由于其外形更贴合人体解剖结构，该偏置型髓内髋钉更易于固定于股骨颈与股骨头的中心位置，且骨折部位的骨块可更接近骨折前的解剖对位状态。本数据集源自一项针对股骨粗隆间骨折患者的对照临床试验，其中50例患者接受新型偏置髓内髋钉植入治疗，另有50例对照组患者接受市售的非偏置髓内髋钉植入治疗。数据集涵盖患者病例资料、骨折分型数据、骨折复位测量结果、X射线影像以及康复结局指标。与对照组相比，接受偏置型髓内髋钉治疗的患者术后康复周期更短，术后活动能力更佳，且更易恢复独立生活能力。
