Medium- to Long-Term Survivorship Analysis Following Copeland Resurfacing Hemiarthroplasty.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 Copeland resurfacing hemiarthroplasty (CRHA) was developed as a bone-preserving alternative to stemmed hemiarthroplasty, offering advantages such as preservation of native anatomy and quicker recovery. However, there is limited evidence regarding its long-term survivorship. Objective The objective of this study is to determine the medium- to long-term survival outcomes and functional results of CRHA performed in a single-surgeon series. Methods A retrospective cohort study was conducted on patients who underwent CRHA between 2007 and 2013 at King's Mill Hospital, Mansfield, UK. There were no inclusion or exclusion criteria; all patients had significant morbidity and radiological evidence of glenoid arthropathy (Walch classification). The Oxford Shoulder Score (OSS) was collected pre- and postoperatively. Kaplan-Meier survival analysis was performed. Statistical analysis was carried out using IBM SPSS Statistics for Windows, Version 28 (Released 2021; IBM Corp., Armonk, New York, United States), with significance set at p<0.05. Results Eighty CRHAs were performed in 72 patients (eight bilateral procedures). The mean follow-up was 79 ± 18 months (range 50-122), corresponding to approximately 6.5 years. The primary indication was osteoarthritis (76.3%), followed by cuff tear arthropathy (CTA) (16.3%), rheumatoid arthritis (RA) (5%), and post-trauma (1.3%). The mean preoperative OSS was 16 ± 5, which doubled postoperatively to 32 ± 8 (p<0.05). Fifteen patients (18.8%) underwent revision surgery, with a mean time to revision of 49 ± 11 months. Projected survival at five, seven, and 10 years was 83%, 81%, and 79%, respectively. Conclusion CRHA improved pain and function in the medium term but demonstrated a higher revision rate compared with other arthroplasty options, particularly in patients with CTA and RA. These findings should guide patient selection and shared decision-making.
