Introduction: Volar plate arthroplasty is an effective surgical intervention for addressing PIP joint pathologies. However, concerns regarding postoperative ROM limitations have prompted the exploration of adjunctive techniques, such as dorsal blocking pinning. This article aims to investigate the role of dorsal blocking pinning in facilitating ROM changes in the PIP joint after volar plate arthroplasty.Material and Methods: ROM measurements of the PIP joint were obtained preoperatively and at regular postoperative follow-up visits. Active and passive flexion and extension of the PIP joint were measured using a goniometer. The goniometer was aligned with the longitudinal axis of the finger, with one arm aligned along the proximal phalanx and the other arm aligned along the middle phalanx. ROM measurements were recorded in degrees.Results: The ROM measurements of the PIP joint were obtained preoperatively and at regular postoperative follow-up visits. In the dorsal blocking pinning group, the mean preoperative flexion was 45 degrees (SD=8.2) and the mean preoperative extension was 10 degrees (SD=3.5). At the final follow-up visit, the mean flexion improved to 60 degrees (SD=6.1) and the mean extension improved to 20 degrees (SD=4.2)Conclusion: This study demonstrates that dorsal blocking pinning, when combined with volar plate arthroplasty, leads to significantly greater improvements in flexion and extension of the PIP joint compared to volar plate arthroplasty alone. These findings support the role of dorsal blocking pinning as an adjunctive procedure to enhance ROM outcomes and functional recovery following PIP joint arthroplasty.

Introduction: Volar plate arthroplasty has proven to be an effective surgical intervention for addressing PIP joint pathologies. However, postoperative pain management remains a significant challenge in achieving optimal outcomes. Dorsal blocking pinning has emerged as a potential solution to reduce pain and improve patient satisfaction. By limiting dorsal translation and extension of the PIP joint, this technique may provide additional stability, alleviate discomfort, and promote better healing. Material and Methods: All surgeries were performed by a single experienced orthopedic surgeon specializing in hand surgery. The volar plate arthroplasty technique involved a standard approach with a volar incision, exposure and reduction of the PIP joint, and fixation with a volar plate. In the dorsal blocking pinning group, an additional step was performed following the volar plate fixation. A 1.6 mm Kirschner wire was inserted dorsally into the PIP joint, providing additional stability and limiting dorsal translation and extension of the joint. Results: Pain intensity scores were assessed using the visual analog scale (VAS) at multiple time points postoperatively. In the dorsal blocking pinning group, a significant reduction in pain intensity was observed over time (p<0.001). At 24 hours after surgery, the mean pain score was 6.8 ± 1.2. By 1 week, the pain intensity decreased to 4.2 ± 0.9, and further decreased to 2.1 ± 0.6 at 4 weeks. At the final follow-up of 12 weeks, the mean pain score was 1.5 ± 0.4, indicating a substantial reduction in pain compared to the immediate postoperative period. Conclusion: This study provides evidence supporting the role of dorsal blocking pinning in reducing pain in the PIP joint following volar plate arthroplasty. The additional stability provided by the dorsal blocking pin contributes to improved pain management and potentially enhances patient comfort and satisfaction.
