The role of wrist anthropometric measurement in idiopathic carpal tunnel syndrome

Anthropometric wrist measurement ratios were examined for an association with idiopathic carpal tunnel syndrome (CTS). Wrist measurements were recorded in 67 patients with CTS and in a matched control group of 67 healthy volunteers. The Wrist Ratio (WR) (wrist anterior to posterior dimension/wrist medial–lateral dimension) and the Wrist Palm Ratio (wrist anterior to posterior dimension/palm length) were calculated for each case. We found that a WR of ≥0.70 and a Wrist Palm Ratio of >0.342 were significantly associated with idiopathic CTS
