Elbow hemiarthroplasty for unreconstructible distal humerus fractures: a case series.
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. 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
backgroundTo evaluate the outcomes of distal humerus hemiarthroplasty (DHH) in a series of eight consecutive patients with unreconstructible distal humeral fractures or failed open reduction and internal fixation (ORIF).
methodsRetrospective data including demographics, postoperative outcomes, and complications were extracted from electronic records at a level 1 trauma center. Surgeries were performed by a single fellowship-trained upper extremity surgeon. The indications for DHH were unreconstructible distal humerus fracture or failed ORIF. Eventually, as accepted by current literature, no weight restrictions were applied. Range of motion (ROM), functional scores, and pain levels were evaluated during follow-up appointments. Minimum follow-up time was 12 months.
resultsBetween 2014 and 2024, eight consecutive patients underwent DHH. The mean patient age at the time of surgery was 68.1 years, with an average follow-up of 46.6 months. Patients exhibited satisfactory ROM, with near-complete pronosupination and mean flexion and extension of 125° and 25°, respectively. Functional scores, including Quick Disabilities of the Arm, Shoulder and Hand score (35.2) and Mayo Elbow Performance Score (78.1), were good. Mean Numeric Pain Rating Scale was 3.9. Complications included two conversions to total elbow arthroplasty due to elbow instability and postoperative infection (staged conversion), one ligament reconstruction for postoperative elbow instability, two cases of ulnar periprosthetic fracture, and one case of ulnar nerve neuropathy.
conclusionsDHH for unreconstructible distal humerus fractures and failed ORIF allows for unrestricted postoperative lifting and yields satisfactory functional outcomes but does have a relatively high complication rate. Level of evidence: IV.
