Impacted intra-articular fractures and fracture dislocations of the middle phalanx base are challenging to treat because of troublesome joint reduction and difficulties in achieving articular congruity. Although treatment algorithms have been published, the anatomically delicate proximal interphalangeal joint often remains incomplete in function and may result in post-traumatic pain, stiffness, and osteoarthritis. This article describes a percutaneous intramedullary reduction technique for impacted middle phalanx fractures as a treatment option to achieve articular congruity with minimal surgical trauma. The reduction technique may be considered for selected patients with impacted fractures of the base of the middle phalanx with or without joint dislocation.
