Efficacy analysis of small-incision in situ decompression under ultrasound combined with shear-wave elastography in the treatment of ulnar neuropathy at the elbow.
Article in International orthopaedics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundCurrently, the primary treatment for ulnar neuropathy at the elbow is open in-situ decompression surgery. The effectiveness of ultrasound localization therapy, especially small-incision surgery using ultrasound combined with SWE, remains unclear.
objectivesTo evaluate the effect of small-incision ulnar nerve release in treating ulnar neuropathy at the elbow by ultrasound combined with shear wave elastography (SWE).
methodsA retrospective analysis of 98 patients treated in our hospital for ulnar neuropathy at the elbow was conducted from June 2023 to March 2025. According to the treatment style, these patients were divided into a traditional open in-situ decompression surgery group (n = 51) and an ultrasound combined with SWE small-incision surgery group (n = 47). The maximum proximal Cross-sectional Area (CSA), Sensory Conduction Velocity (SCV), Motor Conduction Velocity (MCV), modified Bishop score, Quick-DASH score, and Visual Analogue Scale(VAS) score were compared between the two groups. Additionally, the amount of intraoperative blood loss, operation duration, hospital stay, patients' satisfaction with postoperative incision aesthetics, the postoperative complications of different operation methods, and the degree of damage to the medial cutaneous nerve of the forearm were studied.
resultsAll patients underwent surgical treatment, with preoperative ultrasonography confirming no ulnar nerve subluxation. No statistically significant differences in age, preoperative SCV, MCV, CSA, Quick-DASH score, or VAS score were found between the two groups. The postoperative and the last follow-up SCV, MCV, and CSA were similar in the two groups. In addition, the improved Bishop score, Quick-DASH score, VAS score, postoperative hematoma rate, elbow stiffness rate, and postoperative protection of the medial cutaneous nerve of the forearm in the ultrasound combined with SWE surgery group were better than those in the traditional open surgery group. What's more, compared with the traditional open surgery group, the ultrasound combined with SWE surgery reduced the amount of intraoperative blood loss, shortened the operation duration and hospital stay, and the patients were more satisfied with the scar of the incision.
conclusionsFor patients with ulnar neuropathy at the elbow who are amenable to in situ decompression, this study highlights the potential of preoperative ultrasound combined with SWE to guide a targeted, minimally invasive surgical approach.
