Treatment alternatives of congenital hand differences with thumb hypoplasia involvement.
Congenital thumb hypoplasia is a complex and heterogeneous congenital difference that is detrimental to hand function. Apart from its' classic form, which is now considered to be part of radial dysplasia, it can occur as part of other congenital anomalies including, syndactyly, symbrachydactyly, atypical cleft hand, bifid thumb, triphalangeal thumb, mirror hand, constriction band syndrome, as well as generalized anomalies and syndromes. Management is aimed primarily at restoring basic hand function, specifically, power grasp and precision pinch, and secondarily to improve cosmoses, which inevitably is going to be impaired. Several treatment alternatives have been proposed to manage the specific disabling condition and include, 1st web space reconstruction and opponensplasty, pollicization, toe-to-hand transfer, distraction lengthening, free toe phalangeal transfer or the use of allograft, stabilization of the metacarpophalangeal joint, and surgery of "spare parts." The purpose of this study is to evaluate the various alternatives available today and propose an algorithm applicable for the appropriate management of thumb deficiency, based on their specific characteristics.
