RESUMO
Swan-neck deformity of the fingers is a cause of functional and cosmetic deficit for most of the patients, the main pathology lies on the PIP joint and most of the surgical treatments depends on the integrity of the soft tissues around it including sublimins tendon that plays an important role in the success of most of the surgical procedures to describe anew surgical technique for the treatment of post - traumatic swan-neck deformity in the fingers. nine patients with post-traumatic swan-neck deformity with intact [FDS] were included in this study. The operation included transferring the insertion of one slip of the sublimins to the A4 transverse pulley this allowed a more dynamic PIP and a better hand function in comparison with other known operations further studies with larger sample and longer period of follow up may give better and more accurate results about this new procedure that can be regarded as a modified Tonkin technique
