Background: An abnormal hallux interphalangeal angle may be an important risk factor for the recurrence of ingrown toenails.
Methods: In this study, sixty pediatric patients who underwent surgery for an ingrown toenail were evaluated retrospectively in terms of recurrence. The patients were divided into two groups. Group 1 included 30 patients (22 male, 8 female) with hallux valgus interphalangeal deformity. Group 2 included 30 patients (20 male, 10 female) without toe deformity.
Results: The mean age was 12.8±1.42 years and 12.5±1.45 years for patients in Group 1 and in Group 2 respectively. There was no statistically significant difference between the patient and control group in terms of age and gender (p>0.05). The mean follow-up time was 40 months. We observed recurrence in six patients (20%) in Group 1 and in 2 patients (6.6%) in Group 2.
Conclusion: We concluded that the recurrence of an ingrown toenail may be associated with increased hallux interphalangeal angle in pediatric patients. Factors related to the hallux interphalangeal angle abnormality, which increases the risk of ingrown toenails, also increase the recurrence rate in these patients. Therefore, it is surmised that hallux valgus interphalangeal deformity should be evaluated before surgery, and patients and their families should be informed about the risk of increased recurrence.
