Solutions to challenging digital replantations.

Replantation of amputated digits remains one of the most challenging areas in plastic and reconstructive surgery. Complicated cases of digital amputation, such as fingertip amputations, multidigital amputations, and so forth, pose an even greater challenge, requiring extraordinary solutions for successful replantation. The authors present their experience with complicated digital replantations at the University of Medicine and Dentistry of New Jersey-New Jersey Medical School. Cases presented include fingertip replantation, replantation of a finger with impairment of arterial inflow, and two cases of multidigital amputations. In one case of multidigital amputation, heterodigital replantation was performed, and in the other case, a minute skin neurovascular free flap from a nonreplantable finger was used for the reconstruction of another injured finger. Presented cases demonstrate various tools that can be successfully used in the performance of challenging digital replantations.
