Assessment of trochanteric vascularity using quantitative magnetic resonance imaging in a cadaveric model.
Article in Journal of experimental orthopaedics, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Purpose: Few studies have assessed trochanteric vascularity despite its implications for bone healing and surgical approaches. This study aimed to assess the regional arterial contributions of the medial femoral circumflex artery (MFCA) versus the lateral femoral circumflex artery (LFCA) to trochanteric vascularity. Methods: Ten adult human cadaveric pelvises to mid-femur specimens were obtained. One hip was randomly assigned experimental (either MFCA or LFCA MRI-contrast infusion) and contralateral as control (MFCA and LFCA magnetic resonance imaging [MRI]-contrast infusion). Vascular dissection was performed for MFCA and LFCA cannulation. Pre- and post-contrast 3T MRI was completed, and intra-osseous contributions were quantified by region: greater trochanter (GT), intertrochanteric (IT), lesser trochanter (LT) and subtrochanteric (ST). A polyurethane compound mixed with barium sulfate was injected into the LFCA cannula, and into the MFCA cannula for the contralateral hip. Computed tomography (CT) imaging was completed to assess terminal branch locations. Results: MFCA provided the majority of arterial contributions to the full trochanteric region (68.5% MFCA, 31.5% LFCA; standard deviation [SD]: 10.7%, Conclusions: MFCA provided the dominant trochanteric arterial supply, which highlights MFCA's importance to overall hip vascularity. LFCA's trochanteric contribution was smaller but still provided trochanteric contributions, especially the GT region. Knowledge of trochanteric arterial contributions can be beneficial for optimizing surgical approaches and fixation to protect terminal branches during trochanteric fracture, nonunion treatment and trochanteric osteotomies. Level of Evidence: Not applicable.
