1 · What the graph read from 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.

2 · The registry

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

purposeThis study investigated clinical outcomes of posterior cervical foraminotomy (PCF) in patients who previously underwent cervical disc arthroplasty (CDA) at the same level. As CDA becomes more widely adopted and indications expand, a subset of patients will inevitably experience postoperative symptoms. PCF may provide symptomatic relief for persistent or recurrent radiculopathy without the need for revision arthroplasty or conversion to fusion.

methodsA multicenter retrospective chart review was conducted, identifying a consecutive series of patients (n = 17) who received same-level PCF after CDA. Improvements after PCF in arm pain, neck pain, and Neck Disability Index (NDI) were tested using paired Wilcoxon signed-rank tests. The percentage of patients who met MCID for each outcome measure was calculated.

resultsPCFs were performed at one (70.6%) or two (29.4%) levels. Average time from CDA to PCF was 87.4 weeks; average length of follow-up after PCF was 104.3 weeks. Arm and neck pain significantly improved respectively from an average of 5.1 and 4.9 preoperatively to 2.4 and 3.4 postoperatively (p = 0.008 and p = 0.011), with MCID respectively met by 75.0% and 68.8% of patients. NDI scores did not significantly change (p = 0.234). Post-operative instability was not encountered after PCF. Two patients (11.8%) underwent a reoperation after PCF involving removal of the artificial disc and conversion to anterior cervical fusion.

conclusionPCF was beneficial in the cohort overall without producing segmental instability or increasing complexity of necessary larger revision surgeries. PCF should be considered to address persistent or recurrent symptoms in patients with prior CDA.
