Refining the far-lateral pathway: ten-year outcomes of posterolateral transforaminal resection of spinal tumors.

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
objectiveThe posterolateral transforaminal approach, which has been used to treat foraminal and far-lateral disc herniations for a long time, has also become a reliable method for accessing spinal tumours. This method takes advantage of the neural foramen's natural anatomical pathway, which allows for the removal of the tumour with minimal damage to the surrounding osseoligamentous structures. This study examines 10 years of spinal tumours treated with this method by a single experienced neurosurgeon.
methodsA total of 40 patients who underwent 40 surgeries between 2008 and 2018 were reviewed. We examined the patients' demographics, the location of the tumour, the histopathological diagnosis, the extent of the resection, and the surgical outcomes. The lesions were located in the lumbar region, and the same posterolateral transforaminal technique was employed for all surgeries.
resultsThe cohort included 21 men and 19 women in the group, and the average age was 49.2 years (range: 14-75). Schwannomas (n = 27) and metastatic tumors (n = 9) were the most common histopathologies. In 38 cases, the whole tumor was removed, and in 2 cases, only part of it was removed. The method made it possible to safely and effectively reach the lateral and anterior spinal canal compartments, with few complications and good results after surgery.
conclusionThe posterolateral transforaminal approach represents a reliable, minimally invasive corridor for the surgical management of selected spinal tumours. Our decade-long, single-surgeon experience supports its utility in achieving adequate resection with minimal morbidity, especially in tumours localised to the far lateral and foraminal zones of the spine.
