Bone grafts for scaphoid fracture nonunion: a review of research advances / 中华创伤骨科杂志

ABSTRACT

In all the carpal fractures, scaphoid fracture is the most common in clinic (from 60% to 70% in proportion) and likely leads to nonunion. If nonunion is not treated in time, it probably causes instability of the scaphoid lunate joint, further leading to scapholunate advanced collapse. Its comprehensive manifestations include degenerative arthropathy of radial styloid process, radial scaphoid joint, capitulolunate joint and even total wrist joint, eventually leading to wrist joint dysfunction. Therefore, more and more attention has been paid to treatments of scaphoid fracture nonunion. Bone grafting is the most common practical treatment, but new surgical procedures have emerged in recent years. This article thus reviews the research advances in bone grafting for scaphoid fracture nonunion, commenting on the advantages and disadvantages of various techniques.
