A case of dorsal fracture–dislocation of the proximal interphalangeal joint in which the volar plate had been pulled from its distal attachment without bony or cartilaginous attachments and the lip of the volar plate had also been detached separately and was obstructing full flexion of the joint is presented. A tentative mechanism of causation of this unusual variant of a common injury is suggested.

AbstractProximal interphalangeal joint (PIPJ) fractures and fracture-dislocations are common hand injuries and recognition of this injury pattern is essential in the management of these fractures. Although a variety of treatment options have been reported in the literature, the optimal treatment remains controversial. MEDLINE, EMBASE, and The Cochrane Library Database were screened for treatment strategies of PIPJ fracture and fracture-dislocation. Demographic data and outcome data were collected and recorded. A total of 37 studies including 471 patients and 480 fingers were reviewed. PIPJ range of motion (ROM) was greatest postoperatively in patients who underwent volar plate arthroplasty at 90.6 degrees. Dynamic external fixation resulted in the lowest PIP joint ROM with an average of 79.7 degrees. Recurrent pain and osteoarthritis were most often reported in extension block pinning at 38.5 and 46.2%, respectively. Open reduction and internal fixation had the highest rate of revision at 19.7%. Overall, the outcomes of PIP fractures and fracture-dislocations are based on the severity of injury, and the necessary treatment required. Closed reduction with percutaneous pinning and volar plate arthroplasty had good clinical and functional outcomes, with the lowest complication rates. Hemi-hamate arthroplasty and dynamic external fixation were utilized in more complex injuries and resulted in the lowest PIPJ ROM. This is a therapeutic, Level III study.

Background: Proximal interphalangeal joint (PIPJ) dorsal fracture dislocations (DFD) are challenging injuries. Treatment aims to achieve stability of the PIPJ after reduction so that early motion can be initiated. We studied how increasing articular destruction would affect post reduction stability and investigate the amount of traction and PIPJ flexion needed to maintain the reduction. Methods: Increasing amounts (20%, 40% and 60%) of damage to the volar lip of the middle phalanx in cadaveric specimens were created to represent PIPJ DFD that were stable, of tenuous stability and frankly unstable. Traction forces and PIPJ flexion needed to maintain the reduction were then measured. Results: The PIPJ DFD with 20% damage were stable and did not subluxe while the one with 40% articular involvement was stable after reduction. For unstable the PIPJ with 60% involvement, the more the PIPJ was flexed, the less traction force was needed to hold the joint in reduction. For PIPJ flexion of 20 degrees, a minimum 4.4N of force is needed to maintain reduction while PIPJ flexion of 10 degrees required a minimum 5.0N of force. No amount of force could maintain PIPJ reduction if traction was performed in full extension. Conclusions: In our model, PIPJ DFD with less than 30% articular damage are stable while those with 30% to 50% of involvement have tenuous stability. For the unstable PIPJ DFD, traction obviates the need for excessive flexion of the PIPJ to maintain joint reduction. This information should be considered in treatment modalities for PIPJ DFD, as well in the design of external traction devices for the treatment of PIPJ DFD.

We reviewed 20 cases of chronic dorsal fracture-dislocation of the proximal interphalangeal joint, with a mean follow-up period of 74 months. In patients without comminuted palmar fragments, open reduction and internal fixation or osteotomy of the malunited fragment provided good results. In treating patients with damaged articular cartilage or with comminuted palmar fragments by palmar plate arthroplasty, poor results were obtained because of secondary osteoarthritic changes.
