Femoral neck fractures in patients with prior lower-limb amputation: a two-case series and narrative review of surgical decision-making.
Article in Frontiers in surgery, 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
Background: Femoral neck fractures in patients with pre-existing lower-limb amputation are rare clinical conditions that pose unique technical challenges and surgical decision-making dilemmas for orthopedic surgeons. Altered hip biomechanics, reduced bone mineral density, and dependence on prosthetic ambulation complicate preoperative planning and postoperative rehabilitation, and no unified therapeutic consensus has been established in clinical practice ( 1- 5). Case presentation: We report two distinct clinical cases of femoral neck fractures in amputees managed with different surgical strategies. The first patient was a 55-year-old male with ipsilateral transfemoral amputation who sustained a minimally-displaced Garden II femoral neck fracture and underwent closed reduction combined with cannulated compression screw (CCS) internal fixation. The second patient was a 70-year-old male who experienced left transtibial amputation in a mining accident in 1984; he sustained a fully-displaced Garden IV femoral neck fracture and received primary total hip arthroplasty (THA).Total follow-up was 12 months for Case 1 and 6 months for Case 2. Both patients achieved satisfactory short-term functional recovery, with validated functional scores recorded at final follow-up, and no major perioperative complications occurred. Conclusions: This two-case series combined with a narrative review highlights the need for individualized surgical strategies for amputees with femoral neck fractures. Based on our limited clinical observations, internal fixation may be suitable for younger patients with minimally-displaced fractures and preserved pre-injury hip function, whereas THA may yield favorable functional outcomes in elderly patients with completely-displaced fractures. The proposed treatment algorithm should be regarded only as experience-based guidance rather than universal clinical recommendations.
