Chronic fracture dislocations of the proximal interphalangeal joint. Treatment by the "S" Quattro

The "S" Quattro has proved its value in the treatment of acute displaced comminuted intraarticular phalangeal fracture dislocations. We have used the system to treat five cases of chronic fracture-dislocation or subluxation of the PIP joint. At an average follow-up period of 16.4 months, there was a mean increase in the range of movement of the injured joint by 75 degrees. We recommend this technique for selected cases.
