[Replantation of the ring finger]

Tearing of a finger caught by a ring or by another similar mechanism is a rare but spectacular accident. The lesions vary from simple cutaneous erosion to complete separation of the extremity, which is the most spectacular and most difficult to treat. Reimplantation techniques are now well developed and involve very long vascular by pass to perform sutures in healthy zones. The operation is thus technically difficult, it can have a favourable course in some cases whereas in others, despite the use of meticulous technique, it can lead to thrombosis and failure of reimplantation. Alternatives to reimplantation can nevertheless obtain an esthetic hand, by regularisation or by intracarpal osteotomy. However, it appears of interest in young, motivated patients to propose reimplantation using microsurgery.
