Modified proximal interphalangeal joint palmar plate arthroplasty after fracture dislocation: a case report.

We present the results of treatment of a neglected fracture of the base of the middle phalanx of the ring finger, with dorsal proximal interphalangeal joint dislocation. A modified palmar plate arthroplasty technique was used with the removal of bony remnants and non-anatomic palmar plate insertion to the fracture site. At one-year follow-up the patient showed excellent recovery with an active range of motion of the ring finger of 290° (93% of the other side), strong total grip (48 kg) and a quick DASH score of 11. X-ray images showed perfect re-building of the palmar lip of the base of the middle phalanx with no signs of arthritis. Other options for the treatment of acute and chronic PIP joint fracture dislocations are discussed.
