Outcome of two types of surgical correction of the extra phalanx in triphalangeal thumb: Is there a difference?
Journal of Hand Surgery (European Volume) , Volume 41 - Issue 3 p. 253- 257
The surgical strategy of treatment of the opposable triphalangeal thumb is correction of the radio-ulnar deviation, reduction of the additional length and joint stabilization. The commonest procedures are: (1) removal of the extra phalanx and stabilization of the remaining joint; and (2) a combined reduction osteotomy with resection of the distal joint followed by arthrodesis. We treated 20 patients (33 hands). In 17 hands the extra phalanx was removed, and in 16 hands we used the combined osteotomy procedure of distal joint removal and arthrodesis. None of the patients in either group had an unstable interphalangeal joint. The mean radial or ulnar deviation in the interphalangeal joint was 5° degrees and 9°, respectively. Mean active flexion in the interphalangeal joint was 35° and 46°, respectively, in the two groups. Results for both procedures are similar, for both objective measures and self-rated function and activities of daily living. Either surgical approach seems reliable.
