Complication Rates of Hemiarthroplasty Conversion to Total Hip Arthroplasty Versus Primary Total Hip Arthroplasty.
Article in Orthopedic reviews, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled it.
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
backgroundOne of the most common surgical options for treatment of a femoral neck fracture is hemiarthroplasty (HA). However, progression of arthritis or pain can necessitate conversion to total hip arthroplasty (THA). While conversion to a THA is a viable option, it does carry multiple risks. The purpose of this study was to identify whether performing conversion from HA to THA carries an increased risk of post-operative joint complications when compared to elective THA.
methodsAn administrative claims database was queried to identify patients who underwent conversion from a HA to a THA. Incidences of prosthetic dislocation, prosthetic joint infection (PJI), periprosthetic fracture, aseptic loosening, and revision were collected and compared to elective primary THA with multivariable logistic regression.
resultsPatients undergoing conversion THA had significantly higher risks of all joint complications examined at both 1 and 2 years after surgery. These included prosthetic dislocation (1-year: OR 2.95; 2 years: OR 3.77), PJI (1-year: OR 1.38; 2 years: OR 2.13), periprosthetic fracture (1-year: OR 2.95; 2 years: OR 3.75), aseptic loosening (1-year: OR 6.86; 2 years: OR 7.70), and revision (1-year: OR 3.65; 2 years: OR 6.73).
conclusionPerforming conversion arthroplasty from HA to THA is associated with an increased risk of multiple joint complications in both the short and mid-term follow-up period. Surgeons should consider these complications when indicating HA for femoral neck fractures and elective conversion arthroplasty.
