Posterior Olecranon Fracture Dislocations in Adults: A Systematic Review.

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
Posterior olecranon fracture dislocations (POFDs) were considered posterior Monteggia lesions, which were less described in the literature. The purpose of this study was to provide a systematic review of the diagnosis, treatment, prognosis, and complications of POFDs in adults. A systematic review was performed to identify all relevant studies on the POFDs in the PubMed, Web of Science, Embase, and MEDLINE databases. The methodological quality of the studies was scored using the Methodological Index for Non-Randomized Studies (MINORS). A total of 117 patients were identified in the nine studies selected. The high-energy injuries accounted for 42.7% of the included studies. The rates of concomitant coronoid process, radial head fractures, and lateral collateral ligament injury were 84.6% (99/117), 87.2% (102/117), and 5% (6/117), respectively. The procedure was performed with a dorsal mid longitudinal approach to reconstruct all injury components. The postoperative clinical scores included the Broberg/Morrey rating, with a mean rating of excellent or good at 66%, the mean DASH score was 20.6, and the mean ASES score was 83. The flexion and extension arc and forearm rotation arcs were 100° and 134°, respectively. Complications included arthrosis in 28.2% (33/117) of cases, fracture nonunion or delayed union in 9.4% (11/117) of cases, heterotopic ossification in 7% (8/117) of cases, and the re-operation rate was 16% (19/117). There was nearly no postoperative ulnohumeral instability. The main characteristics of POFDs were disruptions of the trochlear notch, including the olecranon and coronoid processes, and severe radial head fractures, while the lateral collateral ligament was spared. Although the POFDs had a low frequency of instability, the prognosis was relatively poor. The POFDs should be considered independently.
