Long-term survival of CLS Spotorno femoral stem: a systematic review of literature.
Synthesis in Archives of orthopaedic and trauma surgery, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
backgroundCLS Spotorno is a time-tested femoral stem design with excellent early results; the present review was designed to assess the published evidence on CLS Spotorno stem in the literature to evaluate its long-term outcomes and compare it to two other popular stem designs the uncemented Corail™ and the cemented Exeter™ stems. RESEARCH QUESTION: Do CLS Spotorno stems provide adequate long-term rates of survival in terms of revisions and functional outcomes? METHODOLOGY: Medline, EMBASE and SCOPUS databases were searched for relevant articles and a total number of 670 hits were obtained, out of which 14 relevant studies were included in this review. Pooled analysis of revisions rates, subsidence and Harris Hip scores (HHS) were done.
resultsAll the 14 studies were retrospective in design but had sufficiently large follow-up periods (12.3-27 years, mean 17.1 years). Of the 2459 hips reviewed, the documented revision rate was only 6.2%, with aseptic loosening reported in 3.1% and subsidence > 2 mm in 2.6% cases. The overall survival was similar to reported smaller cohorts of Corail (95% at 12 years) and Exeter stems (100% at 17 years). Varus malposition was seen in 10.6% cases, but it did not show any influence on implant survival or revision rates. Distal pedestal formation was seen in 172 of 805 hips across seven studies, while distal cortical hypertrophy was seen in 70 cases out of 398 hips; these were not related with stem malposition. The overall functional outcome was good, with mean HHS of 88.65 (95% CI = 86.08-91.23, p < 0.01). The improvement in scores from preoperative values (of 43.9 points) were comparable to Corail (43.8) and Exeter (45) stems. Thigh pain was seen in only 41 cases out of 1097 hips.
conclusionDespite the limitations due to high heterogeneity of the cumulative data, the review suggests that CLS Spotorno femoral stems provides excellent long-term survival and good hip function. These outcomes are comparable to other commonly utilized femoral stems like the Corail and Exeter. LEVEL OF EVIDENCE: IV.
