Midshaft tibial osteotomy and bone transport for tibiocalcaneal arthrodesis.
Article in Frontiers in surgery, 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
Background: Talar necrosis and infection present a significant challenge, frequently requiring talectomy, which transforms the tibiotalar joint into a tibiocalcaneal articulation. Key management uncertainties persist regarding the necessity of formal arthrodesis vs. the adequacy of a stable fibrous union, and the optimal method for concomitant limb length restoration. This study evaluates a technique combining minimally invasive midshaft tibial osteotomy with Ilizarov distraction osteogenesis to address tibiocalcaneal reconstruction and limb lengthening, seeking to inform these clinical decisions. Methods: Twelve patients who underwent TC arthrodesis at the 920th Hospital of the PLA between January 2014 and July 2019 were included. The cohort consisted of 7 cases of talar infection following open fractures and 5 cases of tuberculous talar infection, all with partial or complete necrosis. Outcomes assessed included bone elongation, fusion rates, AOFAS ankle-hindfoot scores, and postoperative complications. Results: All patients were followed up for 1.5 to 4.5 years. The external fixation frame was maintained for an average of (3.04 ± 0.32) months. Bone transport ranged from 4.3 to 7.0 cm, with a mean of (5.88 ± 1.00) cm. Tibial-calcaneal fusion was achieved in 7 cases, while 5 cases exhibited pseudarthrosis; however, their daily activities were unaffected, and pain levels were mild. The average AOFAS score was (75.92 ± 3.73) postoperatively ( Conclusion: This study highlights the role of minimally invasive midshaft tibial osteotomy in optimizing TC arthrodesis outcomes, achieving functional improvements even in cases of pseudarthrosis. Future research should focus on management protocols for pseudarthrosis to further enhance TC arthrodesis effectiveness.
