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

Table 1: The result of the tissue measurements in affected digits.

		Flexor tendon
	A1 pulley	Anterior-posterior	Radial-ulnar
Neutral position	0.66±0.32	3.99±0.53	6.19±0.80
(N=48)	(0.3-1.7)	(3.1-5.1)	(4.7-8.3)
Hook grip position	0.69±0.35	4.67±0.69	5.73±0.76
(N=48)	(0.3-1.5)	(3.4-6.1)	(4.1-7.5)
Significance (P-value)	0.26	*<0.01*	*<0.01*

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.
