Three-dimensional preoperative planning for adult acute plastic bowing of the ulna.
Article in Trauma case reports, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
caseWe report a case of adult acute plastic deformity of the ulna. Ulnar osteotomy was planned using 3-dimensional (3D) surface data from both injured and intact sides using surface registration technique. Opening wedge osteotomy was planned to correct the position of the ulnar fovea with respect to the proximal ulna. The position of the plate and direction of the screws were decided preoperatively. The operation was performed with reference to a 3D-printed, reduced model. The preoperatively limited pronation and supination of the patient were significantly improved as of 2 years postoperatively. Our preoperative method has several advantages. The risk of nonunion is low because the hinge-side bone cortex remains intact. The surgical procedure is simple, because plate position and direction of drilling are both decided preoperatively. In addition, correction of alignment can be achieved gradually by inserting screws through the plate and checking the range of motion of the forearm.
conclusionOur 3D preoperative simulation aimed to correct the rotational axis of the forearm. The surgical procedure was greatly facilitated using the 3D-printed, reduced model for reference.
