Abstract:
Objective:To evaluate the therapeutic efficacy of modified Ω nail braces and traditional Winograd surgery.Methods:A retrospective analysis was conducted on the medical records of patients with ingrown toenails treated at the Department of Orthopedics of Beijing Tongren Hospital Affiliated to Capital Medical University and the Department of Hand and Foot Surgery, the Fourth People’s Hospital of Langfang City from November 2018 to November 2020. The subjects were divided into two groups: Winograd technique group (WTG) and modified Ω nail braces group (NBG). The basic information of the patients included gender, age, body mass index (BMI), affected side, stage of condition, combined deformity, water exposure, and foot sweating. The occurrence of complications, rate of patient satisfaction, duration of recovery, recurrence rate (the number of recurrences of ingrown nails / the total number of feet), and interval between recurrences were followed up after surgery. The statistical methods employed in this study included two-group t-test and Chi-square test. A significance level of 0.05 was adopted to determine statistical significance. Results:A total of 98 patients with 116 feet were enrolled in the study, comprising 47 cases with 55 feet in the WTG group [33 males and 14 females, age: (31.5±10.8) years] and 51 cases with 61 feet in the NBG group [29 males and 22 females, age: (33.3±13.4) years]. The average duration of nail brace usage in the WBG was (2.7±0.8) months, and the mean follow-up period was (12.3±1.1) months after dismantling. No complications were observed during the follow-up. The mean follow-up duration in the WBG was (12.5±0.9) months. Two patients experienced post-operative infection one week after the surgery, but recovered completely within 60 days through regular dressing changes. In 3 cases, wound exudation occurred following suture removal. However, normal wound healing was achieved with rest and local application of mupirocin ointment. After foot surgery, 2 cases presented with nail spines at a later stage of 2 months, without significant pain or need for further intervention. The two groups did not exhibit any significant differences in terms of gender, age, BMI, affected side, and stage (all P>0.05). The NBG group exhibited a significantly shorter average time of return to work compared to the WTG group [(0.5±0.4) d vs. (13.9±7.3) d], along with a higher patient satisfaction rate (95.1% vs. 83.6% ), both of which showed statistical significance ( P<0.05). No significant differences were observed between WTG and NBG regarding recurrence interval and recurrence rate ( P>0.05). Conclusion:The modified Ω nail brace is equally effective in the treatment of ingrown nails compared to Winograd surgery, but it offers a simpler, more convenient and noninvasive approach. Moreover, patients in the nail brace group exhibited higher satisfaction rates, faster recovery times, and no risk of surgical complications. Therefore, this method can be considered a viable option for treating ingrown nails.
