Impact of operative timing for proximal humerus fracture dislocations on development of neurologic injury.

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
purposeOperative management of proximal humerus fractures with glenohumeral dislocation is often delayed until a shoulder specialist is available. This study aims to assess whether time from presentation to operative intervention impacts incidence of neurologic injury in the preoperative waiting period.
methodsRetrospective review was performed for patients undergoing operative management of a proximal humerus fracture dislocation at a level 1 trauma center. Patient charts were reviewed for patient factors, injury characteristics, neurologic status, and postoperative complications. Statistical analysis comparing patients undergoing operative intervention ≤ 5 and > 5 days from injury was performed (α ≤ 0.05).
resultsOf 52 proximal humerus fracture dislocations, 14% had a neurologic deficit at presentation, and 1.9% had a change in neurologic status prior to operative intervention. 32 injuries (61.5%) underwent operative intervention ≤ 5 days from presentation and 20 (38.5%) > 5 days. There was no difference in neurologic deficit at time of presentation (18.8% vs. 10.0%, p =.077), incidence of preoperative neurologic exam change (0% vs. 5.0%, p =.38), or residual neurologic deficit at final follow-up (9.4% vs. 5.0%, p = 1.0) for the ≤ 5 or > 5 day cohorts, respectively.
conclusionThrough this exploratory retrospective study, no differences were identified for rates of neurologic injury development in the preoperative waiting period between patients undergoing operative intervention ≤ 5 days or > 5 days from presentation for proximal humerus fractures with glenohumeral dislocation, however, this is limited by only 1 patient experiencing a preoperative neurologic change in the > 5 days group. Given the rarity of neurologic injury in the preoperative waiting period and low power of this study, future larger prospective studies are needed to better define the impact of waiting for operative intervention for these injuries. LEVEL OF EVIDENCE: Level IV Case Series.
