Table 1 Comparison of distance to the palmar cuatneous nerve and thenar branch from the relevant borders of PCL, and Length of the PCL measured along the incision

From: Anatomical landmarks for safer carpal tunnel decompression: an experimental cadaveric study

Distance measured along the line of incision (mm) Mean Range
To the palmar cutaneous nerve from proximal border of TCL 8.16 2.45–14.80
To the recurrent branch nerve from distal border of TCL 7.75 2.75–11.55
To the superficial palmar arch from distal border of TCL 11.48 4.00–18.25
Length of the TCL 27.00 20.60–34.25
