What is the risk of dislocation after hip arthroplasty for patients with neuromuscular disease: a systematic review and meta-analysis.
Synthesis in EFORT open reviews, 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
Purpose: Recent research has demonstrated excellent functional outcomes for patients with neuromuscular (NM) disease undergoing hip arthroplasty (HA). However, significant concerns persist regarding a potentially elevated risk of postoperative instability and dislocation in this specific cohort. Therefore, our objective was to synthesize the existing evidence through a systematic review and meta-analysis to evaluate the risks of dislocation in NM patients after HA. The purpose of this study was to answer the following question using a systematic review and meta-analysis: for patients undergoing HA (P), does the presence of a NM disease (I) increase the risk of postoperative dislocation (O) compared to patients without a NM disease (C)? Methods: A meta-analysis was conducted from inception to December 2024, utilizing multiple database searches (PubMed, Embase, Web of Science, and Cochrane Library). Two authors independently selected studies, assessed their quality, and extracted relevant data. Disagreements were resolved through discussion with a third author. A fixed-effects meta-analysis model was used to calculate pooled odds ratios (ORs) with 95% confidence intervals (CIs). Statistical heterogeneity was assessed using the I 2 statistic. Results: Six studies were included, involving 22,803 patients; 2,643 NM and 20,160 non-NM underwent HA. We found the risk of dislocation in the NM group is higher than that in the non-NM group (OR: 1.59; 95% CI: 1.24-2.03; I 2 = 0%); the NM group of elderly patients with combined femoral neck fractures also increases (OR: 1.63; 95% CI: 1.22-2.17; I 2 = 0%). Conclusion: In conclusion, the findings of this systematic review and meta-analysis provide robust evidence that patients with pre-existing NM disease face a substantially elevated risk of postoperative dislocation following HA. Our meta-analysis indicates that patients with NM diseases are at a heightened risk of dislocation following HA (OR: 1.59; 95% CI: 1.24-2.03, P < 0.001). This finding underscores the need for heightened preoperative counseling, meticulous surgical technique, and potentially the use of enhanced stability constructs in this vulnerable patient group.
