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

background and importanceThoracolumbar corpectomy is an essential tool for restoration of anterior and middle column support. However, subsidence remains a problematic complication. This may be partly mitigated by using wide footprint rectangular endcaps that rest on the peripheral and stronger bone of the vertebral endplate. CLINICAL PRESENTATION: In this study, we describe a new technique, named the "buttress technique" that may further reduce subsidence. A 75-year-old woman presented to the emergency department with 2 weeks of falls and severe back pain. She was dependent on a walker, and was found to have a T11 burst fracture with retropulsion and cord compression. An all-posterior transpedicular corpectomy was performed using an expandable cage with large-footprint rectangular endcaps. The buttress technique was used. First, fenestrated pedicle screws above the corpectomy cage are angled caudally such that the tips of the screws are just deep to the surface of the endplate in contact with the corpectomy cage. The pedicle screws below the cage are similarly angled cranially. Second, cement augmentation of the fenestrated screws helps create a more solid endplate and further reduces the chance of subsidence. A case is presented with imaging and no subsidence at 10-month follow-up. A case series of 21 patients is reported with average follow-up of 19 months (range 8-41 months, 1 deceased at 5 months from cancer-related causes) in which all patients demonstrated grade zero subsidence, with average change in defect height of 5.5%.

conclusionThe buttress technique may reduce subsidence after thoracolumbar corpectomy.
