Idiopathic carpal tunnel syndrome (ICTS): Correlation between nerve conduction studies and dynamic wrist ultrasonography
Publication date: Available online 17 September 2018Source: The Egyptian Journal of Radiology and Nuclear MedicineAuthor(s): Mohamed Aboul-fotouh E. Mourad, Hoda Abdel KareemAbstractPurposeTo evaluate accuracy of ultrasound in assessment of the dynamic wrist movements upon the median nerve for cases of idiopathic carpal tunnel syndrome.BackgroundCarpal tunnel syndrome is the most common entrapment neuropathy and need to get better diagnosis especially for equivocal or mild degree cases for better patient outcome.Materials and methods55 patients who diagnosed as idiopathic carpal tunnel syndrome by nerve conduction studies and 25 control group undergoing dynamic wrist ultrasound examination for cross sectional area of median nerve, its shape and carpal tunnel inlet as well as outlet areas.ResultsCross sectional area inlet p value, sensitivity, specificity, PPV and NPV was
ConclusionArterioles can be seen in the safe zone both superficial and deep to the flexor retinaculum. Deep to the retinaculum, they are mainly observed in the proximal aspect of the carpal tunnel and more frequently close to the median nerve.Key Points• Superb microvascular imaging (SMI) enables the visualization of arterioles within the “safe zone” of the carpal tunnel (visible both superficial and deep to the flexor retinaculum).• Arterioles were more frequently observed in the proximal aspect of the carpal tunnel.• Deep to the retinaculum, arterioles were more frequently seen in proximity to the median nerve.
This study aimed to characterize forearm mixed nerve conduction study (NCS) findings in carpal tunnel syndrome (CTS). Eighty-two patients with CTS and 48 healthy controls were enrolled. We directly compared the forearm mixed NCS and ultrasonography results from CTS patients with those from the controls. Correlation analyses were performed to identify the relationship between forearm mixed NCS parameters and ultrasound measurements in CTS. We observed reduced forearm mixed nerve amplitude and increased cross-sectional area (CSA) of the median nerve at the proximal carpal tunnel (CT) inlet in CTS. The forearm mixed nerve amp...
