Comparison of the Thickness of Pulley and Flexor Tendon Between in Neutral and in Flexed Positions of Trigger Finger

Table 2: The result of the tissue measurements in contralateral normal digits.

		Flexor tendon
	A1 pulley	Anterior-posterior	Radial-ulnar
Neutral position	0.38±0.15	3.66±0.54	5.80±0.89
(N=48)	(0.2-0.8)	(2.7-5.0)	(4.0-7.7)
Hook grip position	0.37±0.15	3.95±0.61	5.59±0.82
(N=48)	(0.2-0.9)	(2.7-5.6)	(3.4-7.5)
Significance (P-value)	0.47	*<0.01*	*<0.02*

In each box of the measurements, the mean value ± standard deviation is described in the upper box and value range is described in the parenthesis, respectively. Statistical significance of the comparison between two positions was examined by the paired t-test. Bold and oblique numbers indicate the P-values <0.05.
