Stepping into clarity: high-resolution ultrasound unveils the hidden spectrum of ankle and foot pain.
Article in Journal of ultrasound, 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
purposeHigh-resolution ultrasonography (HRUS) has emerged as an accessible imaging modality for evaluating ankle and foot pain. This study aimed to describe the spectrum of HRUS findings in patients presenting with ankle or foot pain and document the range of pathologies identifiable with this technique.
methodsA prospective descriptive study was conducted over 12 months involving systematic HRUS examination of 40 adult patients presenting with ankle or foot pain. All relevant compartments of the ankle (anterior, posterior, medial, and lateral) and the foot (plantar and dorsal) were evaluated using a standardized protocol. Vascularity was assessed using color and power Doppler imaging. Plain radiographs were obtained in all cases, and MRI or surgical correlation was available in selected cases.
resultsHRUS found 50 pathologies in 40 patients. There were 31 patients with a single pathology, 8 with dual pathologies, and 1 with three pathologies. Ligamentous injuries were most common (21 cases, 36%), followed by tendon abnormalities (14 cases, 28%). Other findings were plantar fasciitis (4 cases, 8%), soft tissue collections with bony irregularities suggestive of tuberculosis (4 cases, 8%), joint effusion with internal echoes (2 cases, 4%), ganglion cysts (2 cases, 4%), and vascular malformations (2 cases, 4%). There was one case each of synovial osteochondromatosis, retrocalcaneal bursitis, synovial sarcoma, and plexiform neurofibroma.
conclusionHRUS identified multiple ankle and foot pathologies, proving especially effective for superficial soft tissues. Its high spatial resolution, dynamic assessment, accessibility, and lack of ionizing radiation support its use as a first-line imaging tool. A planned sensitivity-specificity comparison with MRI, aiming for at least 90% agreement, may validate HRUS and foster research funding. However, limitations such as small sample size, operator bias, and limited MRI correlation warrant cautious interpretation and highlight the need for further research.
