Relationship Between Femur and Femoral Arteries for Identifying Risk Factors for Vascular Injury

摘要: BACKGROUND This study aimed to identify risk factors for vascular injury in proximal femoral fracture through identifying frequency and distances between femur arteries with computed tomography angiography 3-dimensional reconstruction. MATERIAL AND METHODS In a series of 400 participants, based on measurement results regarding the distribution medial femur, portion covering that part was divided into levels A-E. The center region, margin risky area were defined. interested shortest distance outer superficial, deep, perforating (SFAs, DFAs, PFAs) at each level recorded. RESULTS There 173 males 227 females (average age: 63.61±19.18 years) this study. starting point end from 22.55±4.23% 54.56±8.39% whole femur. mainly distributed B (88.2%), C (65.9%), D (40.6%). regions area, most which DFAs PFAs, concentrated (26.93%) (11.81%). CONCLUSIONS mid-shaft level, PFAs easier injure than SFAs when performing internal fixation fracture. We recommended great attention be paid drill screw insertion around prevention iatrogenic injury.
