“…27 In turn, Palve and Palve (2019), reported that increase in BMI or obesity may be the cause of the narrowing of the canal. 31 The correlation between increased BMI and CTS was also reported by Hashimoto et al (2020), where authors considered female gender as an additional risk factor. 32 Ulbrichtová et al, (2020) hypnotized that association between obesity (BMI ≥ 30) and CTS can be explained by either the accumulation of adipose tissue within the carpal tunnel, or edema caused by an increase in hydrostatic pressure within the canal, which exerts a compressive effect on the median nerve.…”

“…Nevertheless, Palve and Palve (2019) did not find a critical WR of 0.70 between CTS and control subjects, reporting that only at high ratios (WR ≥ 0.75) was the difference significant, with BMI increasing proportionally to WR. 31 Similar to WR, WPR was higher in patients with CTS, where higher values corresponded to wider arms, and more severe cases. 22 , 27 , 29 , 31 Nevertheless, with regards to SI, there were no significant differences between the CTS groups, and the control groups.…”

“…However, the authors hypothesized that at this level, BMI also contributes to an increase in the incidence of CTS, with BMI increasing proportionally to WR. 31 According to NOS criteria analysis, Palve and Palve (2019) study scores were considered highquality research. The BMI was significantly higher in females with CTS than in female controls.…”

“… 26 Another study by Palve et al concluded that WR has a progressive correlation with CTS severity, but statistical significance was seen only in moderate and severe CTS. 27 On the other hand, several other studies did not confirm a significant relationship or showed only a weak association. 28 , 29 In the present study, no significant association was observed between WR and MNCSA.…”

Introduction Considering disagreements on the normal range of median nerve cross‐sectional area (MNCSA) and insufficient data in the Iranian population, this study aimed to measure normal MNCSA. Methods In this cross‐sectional study, bilateral upper limbs of 99 subjects were assessed by sonography, and MNCSA was measured at three levels: forearm, carpal tunnel inlet (CTI), and carpal tunnel outlet (CTO). The association between MNCSA and demographic factors was assessed. Results Mean MNCSA was 6.33 mm2 at the forearm, 9.41 mm2 at CTI, and 10.67 mm2 at CTO. MNCSA was significantly higher in males (6.78 vs. 5.94 mm2 at the forearm, 9.98 vs. 8.92 mm2 at CTI, and 11.24 vs. 10.84 mm2 at CTO in males and females, respectively) and taller (>170 cm) subjects in all three levels (6.69 vs. 6.03 mm2 at the forearm, 9.80 vs. 9.02 mm2 at CTI, and 11.27 vs. 10.12 mm2 at CTO in taller and shorter subjects, respectively). MNCSA was not significantly associated with wrist ratio (WR) or body mass index (BMI). Conclusion The normal MNCSA range in the Iranian population is 6.31 mm2 (forearm) to 10.74 mm2 (CTO). MNCSA is significantly higher in males and taller subjects but is not associated with BMI and WR.

External wrist ratio is not a proxy for internal carpal tunnel shape: Implications for evaluating carpal tunnel syndrome risk

Carpal tunnel syndrome (CTS) is highly prevalent, resulting in decreased function and increased need for costly healthcare services. External wrist ratio (depth/width >0.70) is a strong predictor of the development of CTS and has been suggested to be a proxy for internal carpal tunnel (CT) shape. Conversely, sonography can more directly evaluate CT shape. The purpose of our study was to explore the relationship between wrist ratio and sonographic CT measurements to (1) evaluate the reliability of sonographic CT measurements and (2) explore how external wrist measures relate to anthropometric features of the CT. We used sonographic imaging on a sample of healthy participants (n = 226) to measure CT cross‐sectional area, depth, width, and depth/width ratio. We conducted exploratory correlation and regression analyses to identify relationships of these measures with external wrist ratio. Reliability for dominant and nondominant sonographic CT measures ranged from good to excellent (0.79–0.95). Despite a moderate correlation between CT width and depth and their external wrist counterparts (0.33–0.41, p < 0.001), wrist ratio and CT ratio demonstrated weak to no correlation (dominant: r = 0.12, p = 0.053; nondominant: r = 0.20, p = 0.002) and the mean CT ratio was far lower than the mean wrist ratio (0.45 vs. 0.71 bilaterally). Supporting this, we observed several key differences in the relationship between external wrist measures compared to corresponding CT measures. Additionally, regression analyses combining participant factors and CT measurements produced models accounting for less than 15% of the variability in external wrist ratio (linear models) or correctly predicting less than 68% of wrist ratio‐based risk categorization (logistic models). Overall, among healthy young adults, wrist shape is not an adequate proxy for CT shape.
