Clinical Research On Distance Between Peripheral Neurovascular Bundles Of Hip Joint And Bony Landmarks By Magnetic Resonance Imaging

Objective In the treatment of end-stage hip diseases,total hip arthroplasty(THA)has matured as a mature surgical method.As a result of the abundance of muscles and complex structures surrounding the hip joint,it is extremely difficult to expose important anatomical structures during surgery;in addition,the use of sharp instruments such as retractors,acetabular screws,and other instruments during surgery can result in iatrogenic neurovascular injury(INI).As part of this clinical study,magnetic resonance imaging(MRI)will be used to assess the safe distance between the neurovascular bundles surrounding the hip joint and the acetabular wall,as well as to screen out the high-risk factors for this type of iatrogenic injury by combining statistical analysis with basic patient data.Methods A retrospective review of 858 cases of unilateral hip joint MRIs and the clinical data associated with each patient was carried out in the study.Using image processing software,the safe distances between the femoral neurovascular bundle,obturator neurovascular bundle,and sciatic nerve bundle were measured and designated as d(F),d(O),and d(S).By using SPSS software,it was possible to analyze measurement results and clinical data using a single-factor analysis and screen out risk factors which ultimately affected the safe distance,after which the included indexes that had differences were analyzed using multiple-factor linear regression.P < 0.05 is considered to be statistically significant.Results A retrospective review of 858 cases of unilateral hip joint MRIs and the clinical data associated with each patient was carried out in the study.Using image processing software,the safe distances between the femoral neurovascular bundle,obturator neurovascular bundle,and sciatic nerve bundle were measured and designated as d(F),d(O),and d(S).To evaluate the measurement results and clinical data that were consistent with the normal distribution,SPSS software was used for the analysis.To identify the risk factors that ultimately affect the safe distance,the included indexes with differences were analyzed through multiple-factor linear regression,and the included indexes with differences were analyzed by multiple-factor linear regression.P < 0.05 is considered to be statistically significant.Conclusions It has been found that gender,age,height,and weight all have a significant effect on safe distances based on statistical analysis of clinical data.Furthermore,through the quantitative correlation analysis between different safety distances and body parameters,the corresponding calculation formulas were summarized,which provided a reference point for preoperative planning,selection and placement of retractors and screws during surgery.
