Hyperextension-distraction fractures in ankylosing and spondylotic spines: injury profile and treatment results.
Article in International orthopaedics, 2022. 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
STUDY
designCase series study. PURPOSE: To describe demographic metrics, and clinical and radiographical outcomes of surgical treatment in patients with ankylosed spine (ASP) such as diffuse idiopathic skeletal hyperostosis (DISH) or ankylosing spondylitis (AS) and non-ankylosed spines (NAS) suffering from hyperextension-distraction spine fractures.
methodsPatients diagnosed with hyperextension-distraction fractures between 2012 and 2020 were identified. A retrospective analysis of clinical and surgical data was performed. Similarities between patients with ASP and NAS were evaluated by Fisher's exact test.
resultsOf the 22 patients, 13 had ASP (10 patients with DISH, 3 AS) and nine NAS. Most of these injuries involved the thoracolumbar spine (45.4%). All patients with NAS presented some sign of spondylosis: facet joint degeneration, intervertebral osteochondrosis, and anterolateral osteophytes. None of the patients with NAS and 30.7% with ASP suffered low-energy mechanisms (p = .11). All the patients with NAS and 61% of the patients with ASP had associated injuries (p = .04). On average, the instrumented levels were four (range, 2-6), achieving a fusion rate of 94.7% in all groups. Most of the ASP and NAS presented post-operative complications respectively (p = .65).
conclusionHyperextension-distraction spine fractures are not unique in ASP. In patients with spondylosis and high-energy accidents, we should suspect those fractures and rule out associated injuries, fractures in other vertebral segments, and acute spinal cord injury. The four-level instrumentation achieved an effective fusion rate in all patients.
