Pollicization of the index thumb through Buck-Gramcko technique is the classical treatment for aplasia and severe hipoplasia of the thumb. This paper evaluated the efficacy of a modification introduced to Buck-Gramcko procedure. A preliminary study was conducted in 8 patients diagnosed with hipoplasia or aplasia of the thumb and seen at "Frank Pais" orthopedic hospital from January 1st, 2004 to February 28th 2006. Nine surgeries were performed. The average position of palmar abduction was 42,22º. The average rest position in pronation was 118,33º. The average movement arc in palmar abduction was 58,33°. The average movement arc in pronation reached in patients was 123,33°. Eight (88,9%) out of the 9 operated hands succeeded in opposing the new thumb to the rest of the fingers. No patient required a secondary oponoplasty. The outcome was excellent in 4 hands, good in 4 hands and regular in one hand. The introduced modification provided the majority of patients with a good position of the pollicized finger and opposition movement with respect to the rest of the fingers, all of which reduced the possibilities of a second surgery to attain a satisfactory result.
