The impact of postoperative calcaneocuboid joint articular surface gap and step on long-term outcomes in surgically treated calcaneal fractures: a brief 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
backgroundCalcaneal fractures, the most common tarsal fractures, often result in significant long-term disability and impose substantial healthcare burdens. Surgical intervention aims to restore hindfoot anatomy, but the role of calcaneocuboid joint reduction quality in determining long-term outcomes remains unclear. This study evaluated the impact of calcaneocuboid joint reduction quality on functional outcomes and the need for reoperation in surgically treated patients with calcaneal fractures.
methodsThis retrospective cohort study included 42 adult patients who underwent surgical treatment for calcaneal fractures. Postoperative computed tomography (CT) scans were analyzed to assess calcaneocuboid joint parameters, specifically gap and step. Functional outcomes were measured using the Manchester Oxford Foot Questionnaire (MOXFQ), and patient interviews were conducted to document the need for reoperations during the follow-up period.
resultsThe median follow-up duration was 6.5 years. Neither the postoperative gap nor step of the calcaneocuboid joint significantly correlated with MOXFQ total scores (gap: Spearman's r = 0.15, P = 0.336; step: Spearman's r = 0.19, P = 0.239). Additionally, no significant differences in MOXFQ scores were observed between patients with anatomic and non-anatomic reductions (P = 0.548). However, non-anatomic calcaneocuboid joint reduction was significantly associated with a 4.44-fold increased hazard of reoperation in this cohort (hazard ratio: 4.44, 95% CI: 1.48 to 13.31, P = 0.008).
conclusionWhile calcaneocuboid joint reduction quality did not significantly affect functional outcomes, the observed association with an increased hazard of reoperation highlights the need for further research to validate these findings and explore potential clinical implications.
