Introduction

Retronychia is a particular form of post-traumatic ingrown nail associated with repeated microtrauma of the underside of the proximal nail fold. It is caused by the nail embedding backward into the underside of the proximal nail fold, forming multiple generations of nail plate.

Methods

The study aims to evaluate the results of a novel nonsurgical treatment of retronychia. A review was performed on 20 patients who underwent the treatment, 16 having suffered from a chronic form of the condition, with the remaining 4 being afflicted with retronychia for less than a year prior to treatment.

Results

The treatment was a combination of eliminating the proximal sharp edge of the uppermost nail layer and thinning of the nail with fraises and drills of various sizes. This therapy was repeated every 7-14 days. The patients came for checkup every 6 weeks. Treatment duration varied from 2 to 14 months. The rate, at which the appearance of a healthy nail occurred depended on the length of the intact nail layer below the part of the nail affected by retronychia, the age of the patient, and cofactors such as obesity, diabetes, etc. The treatment result in our case study was completely healthy nail growth without relapse of retronychia in all the 20 patients for a follow-up period of 18 months.

Conclusion

By combining a healthy nail growth and the simultaneous protection of the nail, we were able to achieve a normal nail in all cases. In order to maintain the achieved results, we recommended our patients to continue wearing protective tubes whenever they would wear closed shoes because recurrence of retronychia may occur even after minimal trauma.
