Abstract

The objective of this study is to conduct a prospective trial comparing the therapeutic efficacy of Omega toenail correction and the Winograd procedure in treating stage II-III paronychia. From August 2018 to August 2023, ninety cases from eighty-three patients were randomly divided into two groups, one receiving Omega toenail correction (experimental group) and the other receiving the Winograd procedure (control group). The clinical therapeutic effects of both treatments were evaluated based on time to resume movement, treatment cycle, one-year recurrence rate, and visual analogue scale (VAS) scores before and after treatment. The clinical efficacy was compared between Omega toenail correction and Winograd procedure treating paronychia of stage Ⅱ-Ⅲ. It has been demonstrated that the time to resume movement in the experimental group is obviously shorter than that in the control group (P = 0.024), while the treatment cycle is longer (P = 0.009) with no significant difference (P = 0.734) in the aspect of one-year recurrence rate. However, the VAS after the correction in the experimental group is significantly lower than that in the control group (P = 0.019). It has been suggested that Omega toenail correction characterized by easy operation, sure efficacy and lower recurrence rate can be widely applied in clinic work.

How strong is the evidence?

Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
