A Functional Outcome of Closed Intra-articular Fracture of Proximal Interphalangeal Joint of Hand Managed By Suzuki Frame - A Longitudinal Study.
Article in Journal of orthopaedic case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Closed intra-articular fractures of the proximal interphalangeal (PIP) joint are difficult to manage because of the small articular surface, joint instability, and risk of post-operative stiffness. Dynamic external fixation using the Suzuki frame aims to restore joint congruity while permitting early mobilization and functional recovery. Aim: This study aims to evaluate the functional outcomes of closed intra-articular PIP joint fractures of the hand managed with Suzuki frame fixation. Materials and Methods: This prospective study included 32 patients with closed intra-articular PIP joint fractures treated using the Suzuki dynamic external fixation frame. One patient was lost to follow-up; therefore, 31 patients were included in the functional outcome analysis. Patients were followed for 12 weeks. Functional outcomes were assessed using PIP joint range of motion (ROM), quick disabilities of the arm, shoulder, and hand (QuickDASH) score, and post-operative complications. Results: The majority of patients were male (78.1%) aged 17-30 years (56.3%). Slip and fall (43.8%) was the most common mechanism of injury. Mean ROM improved significantly from 42.5° ± 8.3° at 6 weeks to 110.6° ± 9.2° at 12 weeks (P < 0.001). The mean QuickDASH score improved from 99.0 ± 0.0 at 6 weeks to 14.9 ± 4.5 at 12 weeks (P < 0.001). Most patients (81.3%) had no post-operative complications, with only one case each of extensor lag and non-union, and no pin-tract infection or joint instability. Conclusion: Suzuki frame fixation provides excellent short-term functional recovery in closed intra-articular PIP joint fractures by allowing early mobilization, restoring joint motion, and maintaining low complication rates. It is a safe, minimally invasive, and effective treatment option for unstable PIP joint fractures.
