ABSTRACT

Introduction: Hypoplasia of the thumb is a congenital developmental deficiency of the thumb. The incidence is 1/100,000 live births. In these patients it is of vital importance to establish function after the surgical procedure. The T-GAP score has been developed, an evaluation designed with the purpose of determining the usefulness and functionality of the thumbed hand and index finger in patients with thumb hypoplasia types III B, IV and V of the Blauth classification modified by Manske and McCarroll. Objective: To assess the function of the thumbed index fingers and hands using the T-GAP score instrument. Material and methods: Observational, descriptive, cross-sectional. Results: The average age at which surgical treatment was performed is 7.314 years. The average age at which the T-GAP test was performed is 10 years. In relation to the functional result of the total T-GAP test, on average it is 57.42% of global function. The function of the thumb index, on average, is 77.14%. There is an association between the younger age at which the index finger is thumbed, the higher the functional result of the grip and grip (p = 0.005). Conclusions: The use of the T-GAP score in patients undergoing thumbsplasty to treat types III-B, IV and V thumb hypoplasia is completely feasible given the simplicity of its application and applicability in different age groups.
