Outcomes of Tendon Graft Versus Dorsal Capsulodesis Techniques for Chronic Scapholunate Ligament Injury in Adults: A Systematic Review.
Article in Journal of hand surgery global online, 2027. 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
Purpose: Chronic scapholunate interosseous ligament injuries contribute significantly to wrist instability. Surgical management remains challenging, with tendon graft-based reconstruction and dorsal capsulodesis being the most common techniques. This systematic review aimed to compare the clinical and radiographic outcomes of capsulodesis-based versus tendon graft techniques for chronic scapholunate ligament injuries. Methods: This systematic review was conducted per Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A comprehensive search of PubMed, Web of Science, Scopus, and Cochrane Library identified eligible comparative studies. Studies comparing tendon graft techniques and dorsal capsulodesis for chronic scapholunate interosseous ligament injuries in adults were included. The Risk Of Bias In Non-randomized Studies - of Interventions (ROBINS-I) tool was used for quality assessment. Because of data heterogeneity and lack of consistent quantitative metrics (eg, means and standard deviations), a narrative synthesis of results was performed. Results: Across six included studies encompassing 298 patients, tendon graft and tenodesis techniques demonstrated variable postoperative outcomes. Notable heterogeneity existed within the tendon graft/tenodesis category itself: modified Brunelli tenodesis outperformed the four-bone weave in pain relief (visual analog scale reduction 4.8 cm vs 3.2 cm), grip strength, range of motion (ROM) preservation (86% vs 60%), and Disabilities of the Arm, Shoulder, and Hand (DASH) score improvement (31.5 vs 14.2 points). Scapholunate intercarpal ligament similarly outperformed three-ligament tenodesis across grip strength, ROM (113° vs 82°), and patient-reported outcomes. Dorsal capsulodesis provided consistent pain relief, adequate ROM preservation, and lower surgical failure rates in most series, with no statistically significant differences in patient-reported outcome measures compared to tenodesis groups. Radiographic deterioration was observed across all surgical techniques over long-term follow-up without consistent correlation with clinical symptoms. Overall certainty of evidence was very low per Grading of Recommendations Assessment, Development and Evaluation (GRADE) assessment. Conclusions: Neither tendon graft nor capsulodesis techniques demonstrated consistent superiority; outcome differences were more pronounced within technique subcategories than between groups, highlighting the need for standardized, high-quality prospective trials. Clinical relevance: Tendon graft reconstruction and dorsal capsulodesis show comparable outcomes for chronic scapholunate ligament injury. Surgical choice should be individualized based on patient factors, injury characteristics, and surgeon expertise. Given the very low certainty of current evidence, standardized outcome reporting and further high-quality prospective studies are needed.
