Transforaminal Endoscopic Lumbar Discectomy Under Local Anesthesia for Small-Sized Lumbar Disc Herniation in Elite Athletes.
Article in International journal of spine surgery, 2026. 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
backgroundSymptomatic small-sized lumbar disc herniation (small LDH) presents a significant challenge in elite athletes, where rapid return to competition is paramount. This study aimed to characterize the clinical and imaging features of small LDH in this population and to evaluate the efficacy of transforaminal endoscopic lumbar discectomy (TELD) under local anesthesia.
methodsWe retrospectively reviewed the medical records of 11 elite athletes (12 discs) who underwent TELD for small LDH, defined as a herniation not exceeding 25% of the spinal canal's anteroposterior diameter on magnetic resonance imaging. Preoperative assessments included neurological status and magnetic resonance imaging findings, focusing on T2 hyperintensity within or posterior to the posterior longitudinal ligament (PLL). Outcomes were time to return to sport, recurrence, and patient-reported outcomes by modified MacNab criteria at final follow-up.
resultsAll athletes presented with function-limiting radiculopathy despite radiographically small herniations (mean anteroposterior diameter, 3.3 ± 1.0 mm; mean canal occupancy ratio, 16.7% ± 6.6%). T2 hyperintensity in or behind the PLL was present in all 12 discs. Following TELD, all athletes returned to unrestricted competition at a median of 2.0 months (range, 1.5-5.0). At a median final follow-up of 26.0 months, modified MacNab outcomes were excellent in 63.6% and good in 36.4%. No recurrences requiring reoperation occurred.
conclusionsSymptomatic small LDH with associated T2 hyperintensity in the PLL is a distinct clinical entity in elite athletes. TELD under local anesthesia is a safe and effective intervention that facilitates a rapid and reliable return to sport with favorable mid-term outcomes. CLINICAL RELEVANCE: This study provides evidence that TELD under local anesthesia is an effective treatment for elite athletes with symptomatic small LDH, facilitating a predictable and rapid return to high-level competition. The identification of T2 hyperintensity in the PLL as a key imaging marker may help guide surgical decision-making in this specific patient population. LEVEL OF EVIDENCE: 4:
