Children with Amyoplasia often suffer from limited hand use due to a thumb-in-palm deformity. The thumb is underpronated and flexed at the carpometacarpal (basal) joint. The thumb reorientation osteotomy corrects all aspects of the apposition of the thumb by pronating, extending, and abducting the thumb while the stiletto flap augments skin at the 1st web space and the palmar side of the thumb.
