Venous grafts in reimplantation of the thumb

: The Authors analyze their experience of 25 thumb reimplantations and revascularizations within 5 years. The importance of the first finger in the functional hand economy as well as the ratio between reimplantation take rate and degree of functional recovery with regard to the type of trauma, technique used, and possible and incidental complications are underlined. The venous autologous grafts are of great importance in this microsurgical area and they are more and more applied. In most cases, indeed, intimal lesions are more extended than their macroscopic appearance and the tract of damaged vessels is always wider than assessed. The graft interposition solves the problem with the further advantage to preserve the maximal bone length and to avoid especially contaminated areas. The results achieved confirm these statements and the Authors conclude for the absolute need of venous grafts in thumb reimplantations, especially after amputation from avulsion or crush traumas, even though a greater skill is necessary in using this technique.
