Minimally invasive solutions for ischiofemoral impingement: case analysis and evolving surgical strategies.
Review in Journal of hip preservation surgery, 2025. 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
Variations in the femoral version are increasingly recognized as a cause of coxalgia due to impingement or instability. The true prevalence of these variations remains unknown. The authors report a case of bilateral ischiofemoral impingement (IFI) caused by excessive femoral anteversion treated with a subtrochanteric femoral derotational osteotomy and long intramedullary nailing. We report the case of a 22-year-old female patient with deep left hip pain, consistent with IFI, refractory to conservative treatment. Imaging revealed an ischiofemoral space (IFS) of 16 mm and a femoral anteversion of 34°. A subtrochanteric femoral derotational osteotomy stabilized with a long intramedullary nail was performed. At 18 months, the same surgical procedure was performed due to similar symptoms on the right side, with an IFS of 14 mm and femoral anteversion of 35°. Joint mobility was restored bilaterally, and the symptoms were resolved. Lesser trochanter resection has been reported as a surgical option for IFI in small case series. While conventional subtrochanteric femoral derotational osteotomy with plate fixation shows good functional outcomes, pseudarthrosis remains a concern. The authors' minimally invasive technique using the backstroke technique for osteotomy site compression helps prevent this complication while preserving the iliopsoas insertion. In this case study, a subtrochanteric femoral derotational osteotomy effectively treated bilateral IFI associated with increased femoral anteversion. The patient achieved excellent clinical outcomes with complete symptom resolution following successful consolidation of both osteotomies, though subsequent implant removal was performed to facilitate potential future surgeries.
