Femoral neck anteversion measurement assessment: how to establish a unified method and standard

Cai Zhihao1, Xie Zhaoyong2   

Abstract: BACKGROUND: Femoral neck anteversion is widely used in clinical practice such as total hip replacement and congenital dislocation of hip. Accurate assessment of femoral neck anteversion plays an important role in disease assessment, treatment selection and prognosis evaluation. Femoral anteversion can be assessed in a variety of ways, including the use of clinical physical measurements, physical measurements, radiography, CT, magnetic resonance imaging, ultrasound, 3D printing model measurement (model method), intraoperative Kirschner wire measurement, C Arm, self-made instrument measurement and computer-aided design and medical image processing technology.
OBJECTIVE: To seek a unified method and standard to evaluate the femoral neck anteversion by elaborating on the above measurement methods and the differences between different methods.
METHODS: The CNKI and Wanfang databases were retrieved with the key words of “femoral neck anteversion, measurement, evaluation, method”, and the PubMed database was retrieved with the key words of “femoral neck anteversion”. The literature was searched for methods to assess femoral neck anteversion. After excluding irrelevant and duplicate articles, 43 articles that met the criteria were included for review.
RESULTS AND CONCLUSION: At present, the measurement methods of femoral neck anteversion are mainly concentrated in the field of imaging examination, and CT examination method is mostly studied in imaging examination methods. CT has several advantages over other measurement methods. At the same time, both 3D printing technology and artificial intelligence technology need the support of CT image data. CT will play an important role in a unified method for the assessment of femoral neck anteversion in the future.
