Indexalization of the Medius using the Chase technique in squamous cell carcinoma of the index finger: report of a case and review of the literature

Abstract

Introduction: Squamous cell carcinoma is a rare and aggressive lesion. Bone localization is exceptional both in current practice and in the literature. The Chase technique, a surgical technique involving amputation of the index finger with indexing of the middle finger, is used both in oncological surgery and in traumatic surgery. Material and method: We report the observation of a sixty-year-old patient, with no medical or surgical history, who presented for consultation for swelling of the index finger that had been developing for almost four months associated with pain. Technique: The intervention performed was the Chase technique, (amputation of the 2nd ray) which took place successively in a skin phase, a tendon phase and a bone phase. Result: Early rehabilitation was required with good aesthetic and functional results for the hand. Conclusion: Indexing the middle finger has the advantage of ensuring maximum opening of the first corner, minimizing functional discomfort and maintaining good hand strength.
