[Elbow hemiarthroplasty for coronal shear fractures of the distal humerus].
Article in Operative Orthopadie und Traumatologie, 2024. 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
objectiveThe aim of the operation is to replace the articular surface of the distal humerus in cases of nonreconstructible fractures of the distal humerus. INDICATIONS: Active patients with high functional requirements, in whom weight limitation of total elbow arthroplasty should be avoided. CONTRAINDICATIONS: Contraindications include fractures with irreconstructible epicondyles and/or irreconstructible collateral ligaments, as well as ulnohumeral, or radiohumeral osteoarthritis. SURGICAL TECHNIQUE: Following subcutaneous anterior transposition of the ulnar nerve, surgical dislocation of the elbow joint is achieved through a paratricipital approach with release of the soft tissue structures from the humerus. After resection of the trochlea, the intramedullary canal of the humerus is prepared using rasps in order to implant the hemiprosthesis with retrograde cementing. Finally, the medial and lateral collateral ligaments as well as the flexors and extensors are repaired. POSTOPERATIVE MANAGEMENT: Early functional rehabilitation in a hinged elbow orthosis while avoiding varus/valgus stress after wound healing is completed.
resultsBetween 2018 and 2022, 18 patients with coronal shear fractures were treated with elbow hemiarthroplasty. The mean Mayo Elbow Performance Score (MEPS) was 79 (70-95) after a mean follow-up of 12 months. The mean range of motion was 99° (70-130°) in extension-flexion and 162° (90-180°) in pronation-supination.
