ABSTRACT
INTRODUCTION: Pollicization of the index finger as a treatment for aplasia and severe congenital thumb hypoplasia remains a demanding surgical procedure. In aplasias, it is generally well-accepted, less in hypoplasias. However, it is often the only solution to give back to the child the possibilities of a pollici-digital grip, guaranteeing an excellent function of the hand. We decided to evaluate the long-term results of this intervention. MATERIAL AND METHODS: We reviewed all children operated of index pollicization for a congenital aplasia or hypoplasia of the thumb between 2006 and 2018. The evaluation was performed with a specialized reeducator. The analytical and functional characteristics of the neo-thumbs were evaluated, as well as the consequences on the daily life of the child. RESULTS: Thirteen pollicisations were performed on 10 patients. The mean age at surgery was 21 months (10; 43). It was a Blauth stage IIIB in 1 case, IV in 5 cases, and V in 7 cases. Seven children, and eight hands, could be evaluated. The average postoperative follow-up was 6.5 years. The mean age at the examination was 7.7 years (3.3, 12.1). The mean Percival score was 18 out of 22. The adapted video-assisted scoring system had an average score of 11 out of 14. Children described a momentary psychosocial discomfort for 5 of them, and still present in 3 of them. CONCLUSION: The pollicization of the index finger in congenital aplasia or severe hypoplasia (stage IIIB and IV) of the thumb remains for us the only way to create a sensitive thumb, mobile, with satisfactory strength and appearance, and to bring a normal function of the hand. The evaluation of our functional results are good to very good in the majority of patients, and show the benefits give by this intervention.
