Abstract

Introduction: The “Ring finger” is the tearing off of a finger by a ring or similar mechanism. This accident, which has long gone unrecognized, is frequent. This accident is the mainly seen in young adult males, mainly affecting the left 4th finger. There are various therapeutic options.

Methods: We’ve conducted a retrospective study of 30 patients who presented with a ring finger between 2006 and 2016.

For each patient, we studied the epidemiological data, the stage of avulsion according to the Caroll Larrou classification and the surgical techniques used, as well as an analysis of the clinical and functional results and the psychological repercussions.

Results: The majority of patients were classified as Stage IV. We used Coverage by a groin flap of Mac Gregor in most cases.

At an average follow-up of four years and ten months, there were no immediate complications.

Functional results were satisfactory at the last follow-up. Aesthetic results were not great. Nevertheless, the psychological impact was important.

Conclusion: Ring finger is a serious lesion, the poor prognosis despite advances in microsurgery, and the need to promote preventive measures. An urgent, multidisciplinary management is the only way to improve functional prognosis.

Keywords: Finger, flap, microsurgery, post-traumatic stress, ring
