Biomechanical changes in lumbar intervertebral discs after percutaneous endoscopic transforaminal discectomy surgery at different Body Mass Index (BMI) categories.
Article in Journal of orthopaedic surgery and research, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
objectivePercutaneous Endoscopic Transforaminal Discectomy (PETD) is recognized as the leading surgical intervention for lumbar disc herniation (LDH). Moreover, Body Mass Index (BMI) has been established as an independent risk factor for disc reherniation post-PETD. Furthermore, there is a lack of studies investigating the biomechanical changes in the disc post-PETD in relation to diverse BMI levels.
methodsA three-dimensional nonlinear finite element model was developed to simulate the L3-S1 lumbar spine, and a surgical model of the lumbar 4/5 right PETD was also constructed. Forces of 392 N (BMI 20.76 kg/m
resultsWe established normal and PETD surgery model with different BMIs, contributes to understand the equivalent von Mises stresses and maximum deformation of the L4/5 nucleus pulposus with different BMI. The results indicated that the rise in BMI correlates with heightened equivalent von Mises stresses and maximum deformation within the L4/5 nucleus pulposus in both in normal group and PETD surgery group. Besides, the von Mises stress and maximum deformation of the NP in flexion loading are significantly higher than in other loading conditions under the same BMI condition. These values, alongside the occurrence of high-stress areas, display fluctuations across distinct postures, under the influence of BMI. Furthermore, a discernible accumulation of stress was noted within the compromised regions of the nucleus pulposus.
conclusionThe study suggested that patients who undergone PETD surgery should refrain from engaging in strenuous activities especially flexion during early rehabilitation through finite element analysis. For patients with a high BMI, it is advisable to scientifically reduce weight before and after the surgery in order to maintain appropriate stress on the intervertebral disc.
