Abstract
Objective. To evaluate the possibility of using ultrasound elastography to detect early manifestations of sciatic nerve mononeuropathy.
Materials and methods. A comparison of ultrasound elastography data of the sciatic nerve of 30 patients aged 46.0 (23; 54) years with clinical manifestations of sciatic nerve mononeuropathy (experimental group) and 30 patients aged 36.5 (29; 48) years without lower back pain back (control group) was made to achieve this goal.
Results. Assessment results of the diagnostic utility of ultrasound elastography as a method for diagnosing mononeuropathy of the sciatic nerve were as follows (with an asymmetry between the stiffness indices of comparable segments of the symptomatic and asymptomatic sides of more than 22%): AUC - 0,88 (95% CI (0,55; 0,99)), р=0,003; Youden index - 0.87, sensitivity - 87% (95% CI (0,5; 0,99)), р=0,0001; 100% (95% CI (0,5; 0,99)), р=0,0001.
Conclusion. Ultrasound elastography makes it possible to detect changes in the structure of the sciatic nerve in cases where a standard B-mode study does not reveal changes. The presence of clinical signs suggesting mononeuropathy of the sciatic nerve, in the absence of structural changes in the B-mode, should be considered the basis for performing ultrasound elastography in order to detect perineural and intraneural edema, as well as structural changes in the sciatic nerve.
