**5. Conclusions**

A peri-implant fracture near the volar plate of the distal radius represents a very rare injury, but, considering the growing use of plates, its frequency will probably increase. A trauma of high energy associated with poor bone quality (osteoporosis) can determine a re-fracture around the plate, even if the previous implant was stable, as a low energy trauma in delayed union/non-union fracture can do it too. In addition, the new trauma can cause the bending or the breakage of the plate. In the literature, there is not an exhaustive classification for these types of lesions, and our classification describes a specific point of perisynthesic fracture and the treatment algorithm.
