Femoral nerve palsy following Girdlestone resection arthroplasty: An observational cadaveric study.
Article in World journal of orthopedics, 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
backgroundWhen patients with a failed hip arthroplasty are unsuitable for reimplantation, Girdlestone resection arthroplasty (GRA) is a viable treatment option. We report on a patient who was treated with a GRA due to a periprosthetic infection. We discovered partial paralysis of the quadriceps muscle in this patient. We investigated the femoral nerve anatomy, particularly the nerve entry points, to better understand this phenomenon.
aimTo reveal the femoral nerve anatomy with respect to severe proximal migration after GRA.
methodsEight cadaveric hemipelves were investigated. The branches of the femoral nerve were dissected and traced distally. The GRA was performed by the direct anterior approach. Axial stress to the lower extremity was applied, and the relative movement of the femur was recorded. The femoral nerve and its entry points were assessed.
resultsGRA led to a 3.8 cm shift of the femur in vertical direction, a 1.8 cm shift in the dorsal direction, and a 2.3 cm shift in the lateral direction. A 36.5° external shift was observed. This caused stress to the lateral division of the femoral nerve. We observed migration of the femoral nerve entry point at the following locations: (1) Vastus medialis (5.3 mm); (2) The medial part of the vastus intermedius (5.4 mm); (3) The lateral part of the vastus intermedius (16.3 mm); (4) Rectus femoris (23.1 mm); (5) Tensor vastus intermedius (30.8 mm); and (6) Vastus lateralis (28.8 mm).
conclusionMigration of the femur after GRA altered the anatomy of the femoral nerve. Stress occurred at the lateral nerve division leading to poor functional results.
