Analysis of Characteristics of Femoral Neck Fractures in Young and Middle-aged Adults: Based on medical imaging and fracture mapping techniques, the fracture morphology, fracture surface angles, fracture line distribution, comminuted fractures, and bone defects of 159 young and middle-aged patients with femoral neck fractures were analyzed.
Fracture Mapping Method: Using software such as Mimics 19.0, Geomagic Wrap 2017, and 3-matic, through three-dimensional reconstruction, virtual reduction, image overlay, and fracture line extraction, a femoral neck fracture map was drawn to observe the path and distribution of fracture lines.
Fracture Mapping Results: The femoral neck fracture lines form a closed loop surrounding the femoral neck, densely distributed at the top and dispersed at the bottom, possibly involving the femoral intertrochanteric region; the angle between the fracture surface and the anatomical sagittal plane ranges from −39° to +30°; comminuted fractures and bone defects are mostly located at the posteroinferior part of the femoral neck, increasing the difficulty of treatment.
Clinical Significance: Among young and middle-aged femoral neck fractures, the proportion of displaced and unstable fractures is high; the distribution of fracture lines and fracture surface angles affect the outcomes of fracture reduction and fixation. Appropriate treatment plans should be chosen according to fracture characteristics; anatomical reduction and effective fixation are the treatment principles.
