Indications and outcomes of the Coonrad-Morrey total elbow arthroplasty: a systematic review.
Synthesis in Archives of orthopaedic and trauma surgery, 2024. 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
backgroundThe Coonrad-Morrey prosthesis (CMP) is a widely applied semi-constrained implant that effectively counteracts compression and thrust on the hinge. The aim of this systematic review was to evaluate the indications and outcomes of CMP across different aetiologies for which it was implanted. MATERIALS AND
methodsSelected articles were reviewed to extract: population data, surgical indications, preoperative and postoperative clinical outcomes, survival rate, and complications.
resultsA total of 873 TEAs were analysed. The majority of implants (74.8%) were in female, with a mean age of 62.8 years. Rheumatoid arthritis (RA) was the most common indication (69.9%), followed by post-traumatic sequelae (PTS) (12.1%) and acute fractures (FR) (12.1%). Improvement in functional scores were registered with a mean postoperative flexion-extension of 99.0° and a mean pronation-supination of 137.7°. A mean rate of 29.5% (range, 13.3%-71.4%) complications occurred, mechanical failure (9.04%) being the most frequent.
conclusionCMP showed favourable medium- to long-term clinical outcomes for patients with RA and FR, especially when osteosynthesis is not deemed feasible in elderly patients with low joint workload. Although CMP offered restored range of motion and functional improvements, the implant's low overall survival rate and high complication rate require careful consideration, especially in assessing individual patient factors which are then necessary to determine the suitability of CMP as a therapeutic option.
