Abstract:
Objective:To explore the diagnostic value and clinical significance of total volume of quadratus femoris muscle (TQFMV), ischial angle, femoral neck angle (FNV) measured by magnetic resonance imaging (MRI) combined with eccentric distance and lesser trochanter height measured by multi-slice spiral CT (MSCT) in the diagnosis of ischiofemoral impingement (IFI) syndrome.Methods:A total of 82 patients with IFI in Beijing Huairou Hospital from October 2017 to July 2020 were selected as the observation group. In addition, 82 healthy patients who underwent MRI and MSCT were collected as the control group. The general data, MRI and MSCT parameters of the two groups were compared, and IFI influencing factors were analyzed by logistic regression. The correlation between MRI and MSCT parameters and clinical manifestations and the correlation between MRI and MSCT parameters were analyzed. The receiver operating characteristic (ROC) curve was used to evaluate the diagnostic value of MRI and MSCT parameters for IFI.Results:There were statistically significant difference between the two groups of gender, age, MRI parameters (TQFMV, ischial angle, FNV), and MSCT parameters (eccentricity, lesser trochanter height) (all P<0.05). Logistic regression analysis showed that gender, age, MRI parameters (TQFMV, ischial angle, FNV), MSCT parameters (eccentricity, lesser trochanter height ) were all influencing factors of IFI (all P<0.05). MRI parameters (TQFMV, ischial angle, FNV), MSCT parameters (eccentricity, lesser trochanter height) were all related to quadratus femoris muscle (QFM) edema, fat infiltration and pain degree in IFI patients (all P<0.05). The MRI parameter TQFMV of IFI patients was positively correlated with the MSCT parameter eccentricity and lesser trochanter height, while the ischial angle and FNV were negatively correlated with the MSCT parameter eccentricity and lesser trochanter height (all P<0.05). The AUC of MRI parameters (TQFMV, ischial angle, FNV) and MSCT parameters (eccentricity, lesser trochanter height) in the diagnosis of IFI were high, especially the highest in combined diagnosis, reaching 0.859. Conclusions:MRI parameters TQFMV, ischial angle, FNV and MSCT parameters, eccentricity and lesser trochanter height are related to the clinical manifestations of IFI patients. Combined detection of them can improve the diagnostic value of IFI and avoid missed diagnosis and misdiagnosis.
