Implantology of Phalanx Fracture

Abstract

This chapter describes the role of the implants in operative treatment of phalanx fractures such as the surgical stabilization of the bone in order to secure the fracture reduction and to allow an adequate process of bone healing at the same time. Therefore, patients are able to do passive or better active motion and apply load onto the affected bone.This type of hand fracture can be managed with nonoperative or surgical treatment, favoring early mobilization of the injured finger in both cases, and the choice depends on several factors. On the other hand, implant devices are constantly evolving, and can be divided into three categories: (1) Kirshner wires (as temporary or definitive treatment, bearing a list of both advantages and disadvantages), (2) plates and screws (including lag screws, locking plates, and external fixation), and (3) minimally invasive/fracture-specific plates (including low profile, variable angle locking plates and the use of headless screws), all of which remain valid nowadays.Moreover, the choice of the implants depends on the type and site of fracture, the comminution, the involvement of surrounding soft tissue, and surgeon skill. Finally, the hand surgeon may use one or a combination of more implants to obtain an adequate stability.KeywordsPhalanx fractureImplantologyHand fracturePlateStabilityK-wireScrew
