Modified tibiofibular synostosis vs. Burgess stump in a bilateral amputee: a case report.
Article in BMC musculoskeletal disorders, 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
Despite trans-tibial amputation being the most common major amputation, consensus on optimal stump management remains limited. Cohort studies comparing Ertl-tibiofibular synostosis (TFS) and Burgess-type stumps (BTS) have yielded conflicting results. We present the case of a bilateral trans-tibial amputee with a modified TFS on the right and a conventional BTS on the left. Instead of traditional myodesis, a myoplastic sling was created attaching residual tendons distal to the bone bridge to improve tendon sliding and perceptive feedback. Outcomes were assessed via load distribution, temporospatial gait analysis, adaptability tests, postural control studies, the Four Square Step Test (FSST), stair ascent, functional MRI, and tractography. The TFS stump appeared to show greater ambulation efficiency and was preferred during prolonged standing. FSST and circular gait tests revealed unsteadiness on the BTS side. No activated voxels appeared in the left postcentral gyrus during BTS loading. Movement of the TFS stump activated larger clusters in the contralateral precentral gyrus, while BTS movement activated the supplementary motor area. Fiber connections to the cerebellum via the superior cerebellar peduncle yielded more extensive streamline reconstructions during BTS movement. These unique trial conditions highlight subtle functional differences that are often missed in cohort studies but may significantly impact individual patient needs.
