RESUMEN

According to median sensory latency > or = 3.7 ms (wrist-index finger [WIF], 14 cm), median/ulnar sensory latency difference to ring finger > or = 0.5 ms (14 cm) or median midpalm (8 cm) latency > or = 2.3 ms (all peak-measured), 141 Brazilian symptomatic patients (238 hands) have CTS confirmation. Wrist ratio (depth divided by width, WR) and a new wrist/palm ratio (wrist depth divided by the distance between distal wrist crease to the third digit metacarpophalangeal crease, WPR) were measured in all cases. Previous surgery/peripheral neuropathy were excluded; mean age 50.3 years; 90.8 percent female. Control subjects (486 hands) have mean age 43.0 years; 96.7 percent female. The mean WR in controls was 0.694 against 0.699, 0.703, 0.707 and 0.721 in CTS groups of progressive WIF severity. The mean WPR in controls was 0.374 against 0.376, 0.382, 0.387 and 0.403 in CTS groups of WIF progressive severity. Both were statistically significant for the last two groups (WIF > 4.4 ms, moderate, and, WIF unrecordable, severe). BMI increases togetherwith CTS severity and WR. It was concluded that both WR/WPR have a progressive correlation with the severity of CTS but with statistically significance only in groups moderate and severe. In these groups both WR and BMI have progressive increase and we believe that the latter could be a risk factor as important as important WR/WPR

RESUMEN

Carpal tunnel syndrome (CTS) has been correlated to body mass index (BMI) increase. The present study was done in a Brazilian population to compare BMI values in the following groups: first, CTS vs. controls subjects, and, second CTS groups of increasing median sensory latency (MSL). According to MSL33.7 ms (wrist-index finger, 14 cm), median/ulnar sensory latency difference30.5 ms (ring finger, 14 cm) or median palm-to-wrist (8 cm) latency32.3 ms (all peak-measured), 141 cases (238 hands) had CTS confirmation. All were symptomatic; previous surgery and polyneuropathy were excluded; mean age 50.3; 90.8 prcent female. Controls subjects (n=243; mean age 43.0; 96.7 percent female) and CTS cases had BMI calculated (kg/m2). Controls subjects had a mean BMI of 25.43 +/- 4.80 versus 28.38 +/- 4.69 of all CTS cases, a statistically significant difference (p<0.001). The CTS groups of increasing MSL severity do not show additional increase in BMI (28.44 for incipient, 28.27 for mild, 28.75 for moderate and 29.0 for severe). We conclude that CTS cases have a significant correlation with higher BMI when compared to controls subjects; however, higher BMI do not represent a statistically significant increasing risk for more severe MSL.
