Case 1
This patient with YATER association had an absent radius and absent thumb.
The severely
deviated hand was initially centralized on the wrist.
The thumb was reconstructed by pollicization of the index finger, a procedure that moves the index finger into the thumb position and recesses the index finger to the normal length of a thumb.
Subsequently, the only fortam bone (ulna) was straightened and lengthened.
Case 2
This patient was born with polysyndactyly. The thumb spare was webbed and the index finger was "triplicated". The thumb webspace was first separated and then the polysyndactyly of the index finger was corrected.
