L5 Pedicle Fracture Following Single-Level L4-5 Posterior Lumbar Interbody Fusion: Successful Outcomes With Conservative Treatment in Two 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
This report describes two cases of bilateral L5 pedicle fractures following L4-5 posterior lumbar interbody fusion (PLIF) for L4 degenerative spondylolisthesis in female patients (68 and 72 years old). While this rare complication typically requires revision surgery with the extension of fixation to the sacrum or ilium, both patients achieved successful healing through conservative treatment consisting of bed rest (4-6 weeks) combined with daily teriparatide therapy (20 µg). The fractures occurred early postoperatively (5 and 36 days) and were detected through CT imaging. Both patients presented with high preoperative L4 sagittal vertical axis values (68 mm and 64 mm). At the final follow-up (36 and 18 months, respectively), both patients were free from neurological deficits with confirmed bone union. These cases represent the first report of successful conservative management of this complication. Early detection through careful monitoring in the postoperative period, particularly in cases with poor sagittal alignment of the lower lumbar spine, may lead to successful conservative treatment and help avoid revision surgery.
