Abstract
1. Patients subjected to the flexor-extensor transplant have been reviewed. The results in forty feet were assessed by direct questioning and examination, and the results of a further five operations were assessed from the records.
2. Worthwhile improvement was gained in a little over half the cases. The chances of success are greatest when the symptoms are mildest.
3. The operation appears to be inadequate in certain respects and it seems doubtful whether it has any advantage over the multiple arthrodesis (Lambrinudi) operation.
