[Vascularized bone transfer of scapula apophysis]. / Transfert osseux vascularisé d'épiphyse scapulaire.

ABSTRACT

The vascularized bone transfer of the scapular apophysis was described for the first time by Gilbert and Téot (1982) [1]. The growing pattern of this specific apophysis has large capacity and the plasticity during remodeling is unique. Primarily used for mandibular reconstruction, the scapular crest is also suitable for humeral or femoral reconstruction as well as for carpal stabilization in radial hand malformation, which is considered to be the main clinical indication. The radial hand malformation is characterized by an insufficient ulnar carpal stabilization which leads to luxation and radial deviation of the carpus. Using the vascularized scapular transfer in volar apposition to the ulnar, it enables enlarging the contact surface area with the carpus, thus stabilizing the wrist. Due to the preserved epiphyseal vascularization, good remodeling and integration of the scapular crest is achieved until consolidation takes place.
