[Simple and composite ulnar island bone transfers in hand reconstructive surgery].

Over several years, the author has devised different techniques for difficult bony reconstruction in hand surgery. It is based on compound island transfers of ulnar origin, harvested from the forearm's lower third with reverses flow vascularization. Because of the variety of arterial ramifications, these transplants can consist, either of a simple bone ulnar fragment or when associated, of compound cutaneous-osseous, or even cutaneous-tendineous-osseous transplants. These transplants based on a clinical experience of 49 cases can be used by retrograde rotation for a variety of indications such a recalcitrant nonunion of the scaphoid bone, Kienböck disease, osteochondroma with fracture, or severe post-traumatic sequellae. These procedures performed in one operating time permit reconstruction by using vascularized bone and offer large potential solutions improving bone healing.
