Failure of the linkage mechanism in a semi-constrained total elbow arthroplasty is a rare and unpredictable event: a review of seven cases.

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
purposeLinked component of total elbow arthroplasty (TEA) consisted of bushing and locking pins. Failure of linked components is a rare complication of TEA. This study aims to investigate the mechanism and consequence of failure of the linkage mechanism in TEA surgeries.
methodsBetween 2010 and 2021, five patients received revision operation due to linked component failure. Besides, two patients underwent primary operation at another institute were also analyzed due to failure of the linkage mechanism.
resultsAll seven patients underwent primary TEA and mean age for primary TEA was 48 (range, 27-62). Two patients had TEA for post-traumatic arthritis, three patients for rheumatoid arthritis, and two patients for comminuted distal humerus fracture. The average time between primary TEA and revision TEA for linked component failure was 13.6 years. Three bushing wear and four locking pin dissociation were diagnosed according to pre-operative radiography. Elbow pain and swelling are the most common clinical symptoms. Severe osteolysis, periprosthetic fracture, and stem loosening were noted in three bushing wear cases. In four dissociation of locking pin cases, breakage of male locking pin phalanges was demonstrated in two patients. For revision procedures, both the locking pins and bushings were replaced. No patients in the study required additional surgery after the revision operation for linked component failure.
conclusionOsteolysis, component loosening, periprosthetic fracture may be expected after linked component failure. Patients should be regularly followed up from short-term to long-term with radiography. Early diagnosis and intervention with linked component exchange can prevent extensive revision surgery.
