Factors associated with trigger digit following carpal tunnel release

Table 2 Frequency and proportion for trigger digit diagnosis at < 6 mo, 6-12 mo, and > 12 mo for each surgical group, n (%)

Post-operative time interval	Total diagnoses	Surgical group		P value
		Open (n = 160)	Endoscopic (n = 807)
< 6 mo	12 (1.2)1	4 (2.5)1	8 (1.0)1	0.1212
6-12 mo	13 (1.3)1	3 (1.9)1	10 (1.2)1	0.4612
> 12 mo	22 (2.3)1	4 (2.5)1	18 (2.2)1	0.7742
Total trigger digit diagnoses	47 (4.9)1	11 (6.9)1	36 (4.5)1	0.2252

¹Percentage represents proportion of procedures that developed trigger digit.

²Based on Fisher’s Exact test.
