Adaptive hypertrophy of the digit following little finger to thumb transposition.

This is a long-term retrospective study of eight patients who had undergone little finger to thumb transposition after traumatic thumb loss in order to evaluate the presence of long-term changes in the transposed digit. The transposed little finger, contralateral (nontransposed) little finger, and contralateral thumb were compared using standardized measurements of size, comparison photographs, x-rays, and volume determination using silicone mold impressions of these digits. Significant and marked hypertrophy of the transposed digit was demonstrated in all these patients. Comparison radiographs demonstrated that this enlargement was due to hypertrophy of both soft-tissue and osseous components. This study demonstrates that the little finger transposed to the thumb position undergoes an adaptive hypertrophy to become more thumblike in appearance as well as function.

Frequency of the palmaris longus tendon in North American Caucasians.

The palmaris longus tendon was reported absent in North American Caucasians 24.4% of the time in one or both arms, by Thompson in 1921. Some studies have described its absence as being more frequent in females, and its bilateral absence more frequent than its unilateral absence. This study randomly evaluated 200 Caucasian patients (100 of each sex), seen in an office or hospital setting, for the presence of the palmaris longus tendon. It was absent in one extremity in 3% of the patients. Two and one-half percent of the patients had bilateral absence for a 5.5% total overall absence. This study demonstrated that absence of the palmaris longus tendon in North American Caucasians was considerably lower than reported by Thompson in his report in 1921.
