髋部解剖参数与髋关节旋转袖损伤的相关性:基于髋关节MRI图像OA

Objective To investigate the correlation between anatomical parameters of the hip joint and proximal femur measured on hip MR images and hip rotator cuff injury,and to analyze potential anatomical influencing factors.Methods A retrospective study was performed.74 patients(86 hips)diagnosed with hip rotator cuff injury by bilateral hip MRI in the Department of Radiology,Xuzhou Central Hospital from February 2020 to August 2025 were enrolled as the experimental group.Another 80 age-,gender-and hip side-matched patients(96 hips)with negative bilateral hip MRI results during the same period were selected as the control group.Unilateral hip images were reconstructed from all raw images using the post-processing function of the Picture Archiving and Communication Systems(PACS).The following anatomical parameters were measured and recorded:femoral offset,neck-shaft angle,acetabular abduction angle,acetabular anteversion angle,center-edge(CE)angle,greater trochanter angle,greater trochanter height and proximal femoral length.The differences between each parameter in the experimental group and the control group were compared.Parameters with statistically significant inter-group differences were included in the logistic regression model for further analysis.Results There were statistically significant differences in femoral offset,greater trochanter height,neck-shaft angle,acetabular anteversion angle and CE angle between the experimental group and the control group(P<0.05).Univariate logistic regression analysis showed that all the above variables were statistically significant(P<0.05).Multivariate logistic regression analysis indicated that greater trochanter height(OR=1.268,P<0.001)and acetabular anteversion angle(OR=1.203,P=0.001)were positively correlated with hip rotator cuff injury,and were independent risk factors;CE angle(OR=0.885,P<0.001)was negatively correlated with hip rotator cuff injury,and was an independent protective factor.There were no statistically significant differences in proximal femoral length,acetabular abduction angle and greater trochanter angle between the two groups(P>0.05).Conclusion Hip rotator cuff injury is significantly correlated with femoral offset,greater trochanter height,neck-shaft angle,acetabular anteversion angle and CE angle.Among them,greater trochanter height,acetabular anteversion angle and CE angle are independent influencing factors for hip rotator cuff injury.
