Innovative method for efficient placement of a working cannula in uniportal transarticular full-endoscopic lumbar interbody fusion: transarticular trephonic plasty (TTP).

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
purposeTo evaluate the safety and efficiency of a novel transarticular trephonic plasty (TTP) technique for establishing the working cannula in uniportal transarticular full-endoscopic lumbar interbody fusion (Endo-LIF).
methodsA total of 79 patients with single-level lumbar degenerative disease who underwent uniportal transarticular Endo-LIF were retrospectively divided into two groups: the traditional technique (TT) group and the TTP group. The TTP group underwent cannula placement using the new TTP approach, whereas the TT group used the conventional method. Operation time and fluoroscopy exposure during cannula placement, total surgical time, and early postoperative complications were recorded. Clinical outcomes were assessed using the visual analog scale (VAS) for back and leg pain and the Oswestry Disability Index (ODI) at 3 days, 3 months, and 12 months postoperatively.
resultsThe TTP group showed significantly shorter cannula placement time compared with the TT group (11.4 ± 5.1 min vs. 31.5 ± 9.4 min, p < 0.000). Total surgical time was also shorter in the TTP group (135.7 ± 16.3 min vs. 163.1 ± 23.3 min, p < 0.000). However, fluoroscopy exposure was lower in the TT group. Complication rates were low and did not differ significantly between groups (p > 0.05). Both groups exhibited significant improvements in VAS and ODI scores at all postoperative time points relative to preoperative baselines, with no significant differences observed between groups (p > 0.05).
conclusionThe TTP technique is a safe and efficient method for establishing the working cannula in uniportal transarticular Endo-LIF. It improves surgical efficiency without compromising safety and may help reduce the technical threshold for surgeons, thereby facilitating wider adoption of uniportal transarticular Endo-LIF as a minimally invasive treatment for lumbar degenerative disease.
