Introduction. Polydactyly is defined as an excess of digits or parts in the hand or foot. Thumb (preaxial) polydactyly is commonly found in white and Asian populations. Early surgical management is important to avoid deformations in the affected digit. Methods. Patients were seen at the Instituto Nacional de Pediatria with a diagnosis of preaxial polydactyly during the period from March 2001 to February 2003. Results. Fifty seven patients with an average age of 19 months were observed. We found a prevalence of the masculine (n= 41) in comparison with the feminine gender (n= 16). Two patients had a duplicated thumb on both hands: 39 patients on the right and 16 on the left hand (total= 59 duplicated thumbs). Wassel type IV was the most frequently found polydactyly. All patients had surgical management; 10 patients had minor postsurgical residual deformities. Conclusions. The casuistic reported in this work is significant. Proper classification of this abnormality is important to offer the patient the proper surgery for restoring the hand’s function and aesthetics.
