Ultrasound-guided radial nerve mapping during external fixation for elbow trauma: a case series of 13 patients.
Article in Journal of medical ultrasonics (2001), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
purposeExternal fixation is used in damage control surgeries for severe elbow trauma. However, complications such as pin-site fractures, pin-site infections, and radial nerve injury can occur. Preoperative ultrasound guidance facilitates radial nerve identification and may reduce the risk of nerve injury during surgical pin placement. We aimed to evaluate the clinical use of ultrasound-guided radial nerve mapping during external fixation for severe elbow trauma and assess the occurrence of postoperative radial nerve palsy.
methodsThis retrospective case series included 13 patients who underwent external fixation for severe elbow trauma between April 2015 and October 2023. Patients with active infections, hinged external fixators, external fixators used as definitive treatment, or nerve palsy after injury were excluded. The course of the radial nerve was marked using ultrasonography prior to pin insertion, and pins were inserted via a small skin incision. Complications related to external fixation were assessed.
resultsThe median patient age was 65 years (IQR, 47-72 years) and the median follow-up duration was 700 days (IQR, 475-742 days). None of the patients had radial nerve palsy or pin-site infection. One patient had a pin-site fracture. All patients successfully underwent secondary surgery within a median of 10 days (IQR, 7-13 days) after the external fixation.
conclusionThere were no cases of radial nerve palsy detected with ultrasound-guided radial nerve mapping after external fixation for severe elbow trauma.
