Background:
Many hand surgeons prefer to close palmar wounds with non-absorbable mattress sutures. Suture removal can be painful and time-consuming. In this study, we investigated if suture removal can be facilitated by including a vessel loop in wound closure following open carpal tunnel release (CTR).
Methods:
Overall, 47 patients aged 18 to 75 undergoing elective primary open unilateral CTR completed this unblinded, prospective randomized controlled superiority trial. Subjects were randomized into 1 of 2 study arms: (1) wound closure without a vessel loop (standard, n = 28); or (2) wound closure with a vessel loop (vessel loop, n = 19). Data were collected on time for wound closure and for suture removal. A visual analog scale (VAS) was used to assess satisfaction and pain with suture removal.
Results:
There were no significant differences between the 2 groups in patient demographics or time for suture placement. Visual analog scale satisfaction with suture removal was significantly lower in the standard group (8.6 ± 2.6) compared to vessel loop group (9.9 ± 0.28, P < .05). VAS pain with suture removal was significantly higher in the standard group (2.6 ± 2.7) versus vessel loop group (0.68 ± 1.1, P < .01). Additionally, suture removal time was significantly longer in standard group (84 seconds ± 83) versus vessel loop group (31 seconds ± 13, P < .0001).
Conclusions:
Addition of a vessel loop in wound closure for primary open CTR increases patient satisfaction and reduces pain with and time taken for suture removal.
