Impact of immobilization period and anterior capsular injury on flexion contracture in distal humerus coronal shear fractures.
Article in Clinics in shoulder and elbow, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundSimple elbow dislocations exhibit residual flexion contracture after long-term immobilization. However, the factors affecting flexion contracture after fixation of distal humerus coronal shear (DHCS) fracture remain unclear.
methodsThis study enrolled 21 elbows in DHCS fracture (group A) from 2007 to 2017 and 30 elbows in elbow dislocation (group B) in 2020, all of whom attended a single trauma center. Group A was divided by immobilization period into less than 3 weeks (A1) and more than 3 weeks (A2). Injury patterns of the anterior capsule were divided into proximal stripping, middle displaced, and distal avulsion on magnetic resonance imaging (MRI) scans. Range of motion and functional outcomes were compared between groups A1 and A2.
resultsAll patients in group A exhibited proximal stripping of the anterior capsule, while group B showed middle displaced (37%) and distal avulsion (63%) injuries (P<0.001). The mean flexion contracture was 2° in A1 and 8° in A2 (P=0.139), demonstrating no significant difference by immobilization duration. Similarly, the groups had no significant differences in Mayo Elbow Performance Score (MEPS) or Disabilities of the Arm, Shoulder and Hand (DASH) scores.
conclusionsFlexion contracture following elbow trauma appears to be more closely related to the pattern of anterior capsule injury than the duration of immobilization. Early identification of anterior capsule injury patterns via MRI could inform treatment decisions, particularly in cases where stable surgical fixation is challenging. Prolonged immobilization may be a viable adjuvant treatment option in such cases. Level of evidence: III.
