Resumen
Objective
This prospective study aimed to compare ultrasonographic parameters in diabetic and non-diabetic carpal tunnel syndrome and to analyze whether the findings are related to the presence of associated polyneuropathy.
Methods
The cross-sectional areas (CSAs) of the median nerve were measured at three sites using high-resolution ultrasound in 63 patients with diabetes mellitus and carpal tunnel syndrome (73 hands), 146 non-diabetic patients with carpal tunnel syndrome (163 hands), and 50 controls (50 hands). The diabetic group included 13 patients with type 1 (15 hands) and 50 with type 2 diabetes (58 hands); of these, 43 also had polyneuropathy. Electrophysiological testing was performed to confirm carpal tunnel syndrome, determine its severity, and assess for polyneuropathy.
