Evaluation of sparing the pronator quadratus for volar plating of distal radius fractures: a retrospective clinical study.

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
backgroundThe most commonly used approach for distal radius fractures is the traditional Henry approach. However, it requires an intraoperative incision of the pronator quadratus (PQ) muscle, which results in a series of complications if the repair of the PQ fails.
aimThe objective of this study was to investigate the efficacy of sparing the pronator quadratus for volar plating of the distal radius fractures.
methodsSeventy-six patients who suffered from distal radius fractures of types 23-B, 23-C1, and 23-C2 as per the AO Foundation and Orthopaedic Trauma Association (AO/OTA) classification were treated with volar locking plate fixation using either the PQ muscle incision and repair (group A, n = 39) or the PQ muscle preservation approach (group B, n = 37). Intraoperative index, postoperative efficacy and complications of patients were recorded and evaluated.
resultsAll patients were followed up for more than one year after surgery. All fractures achieved union. There were significant differences in mean operative time, mean intraoperative blood loss, and mean fracture healing time between the two groups. Still, there were no significant differences in limb function scores between the two groups at the 12-month postoperative follow-up. Outcomes assessed at 1 week, 1 month, and 3 months after surgery demonstrated significant differences in the mean range of motion and pain-related visual analog scale (VAS) between the two groups. As the range of motion and grip strength increased, the VAS scores decreased, and there was no significant difference between the two groups at 12 months postoperatively. Although tendon irritation and delayed carpal tunnel syndrome were more common in group A than in group B (7.6% vs. 0% and 5.1% vs. 0%, respectively), the differences were not statistically significant.
conclusionThe modified Henry approach with sparing pronator quadratus muscle has no significant advantage in the range of wrist motion and upper limb function in the late stage. Nevertheless, the intraoperative placement of the plate under the pronator quadratus muscle can shorten the operation time, reduce intraoperative bleeding, reduce early postoperative pain, promote early activity, and improve the patient's quality of life. It is recommended that the pronator be preserved at the time of surgery.
