Residual bone mass after TLIF treated by TELD under local anesthesia: a case report.
Article in Frontiers in surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Purpose: This paper introduces a postoperative revision technique for transforaminal lumbar interbody fusion, namely, removing a free bone fragment under TELD (transforaminal endoscopic lumbar discectomy) under local anesthesia. It is used to treat the corresponding symptoms caused by the residual bone mass continuously compressing the nerve after transforaminal lumbar interbody fusion. Methods: Patient with a residual bone fragment after lumbar interbody fusion was treated by removing a free bone fragment under TELD under local anesthesia. Results: A case of a patient who underwent transforaminal lumbar interbody fusion (TLIF) and had a free bone fragment compressing the nerve roots after the operation was successfully treated by removing the free bone fragment under TELD under local anesthesia. After the removal, the patient's symptoms in the right lower limb improved significantly, and the pain and numbness were greatly reduced. During the subsequent four-month follow-up period, the symptoms continued to ease, and there were no other complications. Conclusion: The free bone fragment removal under TELD under local anesthesia used in this study is safe and effective, and it can be applied to the treatment of nerve compression caused by the free bone fragment after transforaminal lumbar interbody fusion. We have adopted the AOSpine abbreviation TELD (transforaminal endoscopic lumbar discectomy) and assigned the case to complexity grade IIb (prior surgery + foraminal pathology) per the 2025 two-dimensional classification.
