Thoracic myelopathy secondary to epidural scarring with associated infection following spinal cord stimulation implantation.

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
Background: Spinal cord stimulation (SCS) is a well-established therapy for chronic pain refractory to conventional medical management. While lead migration, hardware failure, and infection are the most frequently reported complications, delayed epidural fibrosis resulting in spinal cord compression is rare. Case Description: A 38-year-old male underwent a thoracic paddle-lead SCS implantation at T10-T11 and subsequently developed progressive gait disturbance followed by paraparesis. Thoracic computed tomography demonstrated marked dorsal epidural fibrosis surrounding the electrode, causing severe spinal cord compression. Explanation of the SCS system resulted in transient neurological improvement. However, this was followed by renewed progression of pyramidal signs. The thoracic magnetic resonance revealed a 4-cm T2-hyperintense, partially calcified epidural mass at T9-T10, with suspected intradural extension and associated myelomalacia. Under neuromonitoring-assisted thoracic laminectomy with microsurgical decompression, the T9/10 lesion was partially removed. Histopathological and microbiological analyses demonstrated chronic inflammatory fibro-adipose tissue, with growth of Conclusion: Delayed epidural fibrosis attributed to chronic infection is a rare cause of delayed postoperative recurrent myelopathy secondary to fibrosis encountered following prior SCS implantation.
