Palmar fracture dislocation of the proximal interphalangeal joint.
Palmar fracture dislocation of the proximal interphalangeal joint is uncommon. Thirteen patients treated for this injury were retrospectively reviewed. There were 9 acute injuries. Seven were treated by closed reduction and percutaneous pin fixation and 2 were treated by open reduction and internal fixation. The 4 chronic injuries (more than 1 month after injury) were treated with open reduction and soft tissue reconstruction. The length of follow-up averaged 55 months. Eight patients were free from pain. Postoperative proximal interphalangeal motion averaged 91 for the acute injuries and 70 degrees for the chronic injuries. Follow-up radiographic findings were notable for an increased height of the middle phalangeal base in 6 patients, articular irregularity in 4, and residual subluxation in 2; however, these changes did not correlate with the clinical results. Complications included loss of reduction in 1 patient, progressive swan neck deformity in 1, and development of an average 25 degrees extension lag of the distal interphalangeal joint in 5.
