Total elbow arthroplasty for unreconstructible distal humerus fracture sequelae in patients less than 40 year old. Long-term outcomes.

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
Background: Total elbow arthroplasty (TEA) is rarely recommended in young patients because of a high risk of early failure. This study analyzes the long-term outcomes of a cohort of post-traumatic TEA patients under 40 years of age who received a linked semiconstrained implant to manage the sequelae of an unreconstructible distal humerus fracture. Material and methods: A review of the patients who received a Coonrad-Morrey prosthesis between 1993 and 2013 to manage the sequelae of a distal humerus fracture identified 16 individuals with a minimum follow-up of 10 years who at the time of surgery were aged 40 years or less. A further patient required multiple implant revisions due to a deep elbow infection that ultimately prevented reimplantation and did not reach the minimum follow-up period. We excluded patients with inflammatory or rheumatoid arthritis. Clinical follow-up included the Mayo Elbow Performance Score, the Quick Disabilities of the Arm, Shoulder and Hand score, and triceps function. Overall satisfaction was also investigated. Radiographs were analyzed for component loosening, bushing wear, and periarticular ossifications. Results: The mean follow-up was 151 (range, 125-225) months. After TEA, mean flexion-extension was 99°; mean pronation-supination was 103°; the mean Mayo Elbow Performance Score was 82, and the mean Quick Disabilities of the Arm, Shoulder and Hand score was 12. At the last follow-up, 10 of 16 patients (62%) required revision surgery, 5 for component loosening, 4 for isolated bushing exchange, and 1 for bushing exchange with triceps reconstruction. Nonetheless, 14 (87%) were satisfied with the procedure. Conclusion: Semiconstrained TEA should be considered as a salvage procedure in young post-traumatic patients with unreconstructible distal humerus fractures. In our experience, TEA can achieve satisfactory outcomes in terms of pain relief, stability, and range of movement. However, at a mean follow-up of 151 months, the long-term complication rate was high (62%). Further studies with larger cohorts are required to validate these findings.
