Lesser Trochanter Osteochondroma as an Etiology for Ischiofemoral Impingement: A Case Report.
Article in Journal of orthopaedic case reports, 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
Introduction: Ischiofemoral impingement (IFI) syndrome is a non-articular source of hip pain caused by compression of the quadratus femoris muscle in the space between the ischial tuberosity and the lesser trochanter of the femur. Among the rare structural causes of IFI, Osteochondroma (OC), a benign bone tumor, can present as a space-occupying lesion, reducing the ischiofemoral space and leading to soft tissue impingement. Case Report: We report a case of a 33-year-old male patient presenting with a six-month history of clicking and progressive left gluteal pain. Examination and Imaging studies revealed a narrowed ischiofemoral space associated with an OC arising from the medial aspect of the lesser trochanter. Surgical resection of the lesion led to complete resolution of the symptoms and restoration of hip function. Conclusion: This case highlights the need for a high index of suspicion for structural causes of IFI and underscores the importance of magnetic resonance imaging in the diagnosis. Early surgical intervention for OC -induced IFI can result in excellent clinical outcomes.
