Impact of screw reinsertion on osteosynthesis stability in Schatzker IV tibial plateau fractures: a biomechanical study.

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
introductionThis biomechanical study evaluated the effect of screw reinsertion with a locking plate on fixation strength and the stability of osteosynthesis in medial tibial plateau fractures using porcine bone. MATERIALS AND
methodsThirty porcine tibiae were divided into three groups: group A (underwent biomechanical testing after medial tibial fixation with a large fragment T-shaped locking plate), group B (underwent plate fixation, followed by the removal of all screws and plates and refixation with the same screws and plates using the same holes before biomechanical testing), and group C (underwent biomechanical testing once after plate fixation, followed by the removal of all screws and plates, refixation with the same screws and plates using the same holes, and then biomechanical testing). The translation pattern of the constructs in each group was examined using cyclic loading tests. The changes in the joint gap and step-off after 2000 cycles were compared among the three groups.
resultsSignificant differences in displacement were observed at 10-100 cycles (group A: -0.01 ± 0.04 mm, group B: -0.02 ± 0.04 mm, group C: -0.13 ± 0.15 mm, P = 0.021). However, no significant differences were found in other displacement and translation measurements among the groups. Regarding the gap and step-off among groups, significant differences were observed in anterior and posterior gap changes. Despite the statistical significance, the absolute displacement values were small, suggesting minimal clinical relevance. These findings indicate that reinserting screws and plates into the same hole may not substantially compromise overall fixation strength.
conclusionScrew reinsertion in the same holes after removal did not significantly compromise the stability of osteosynthesis in this biomechanical model. These findings suggest that reinsertion may be a viable option in revision surgery.
