Magnesium Bioabsorbable vs Titanium Screws in Hallux Valgus Surgery: A Prospective, Randomized Medium-term Trial.
Article in Foot & ankle orthopaedics, 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
Background: Metal implants, the gold standard for osteotomy fixation in foot surgery, do have inherent problems. A relatively high percentage of patients undergoing hallux valgus correction require secondary surgery for metal implant removal. Although available since the 1980s, bioabsorbable implant use in foot surgery has been limited because of concerns of osteolysis and inferior strength. Magnesium screws are bioabsorbable implants without the inherent risks associated with other bioabsorbable implants. We prospectively compared outcomes of MAGNESIX to metal implants in hallux valgus deformity correction. Methods: A prospective, randomized study comparing radiographic and clinical outcomes between hallux valgus corrections fixated with magnesium (24 feet) or titanium (25 feet) screws, with an average follow-up of 44 and 35 months, respectively. Clinical outcomes were assessed using the American Orthopaedic Foot & Ankle Society (AOFAS) forefoot score and radiographic parameters measured on weightbearing radiographs pre-operatively and at final follow-up. All complications were documented. Results: Both magnesium and titanium cohorts showed statistically significant improvements in radiographic parameters ( Conclusion: We found no difference between bioabsorbable magnesium screws and titanium screws for fixation in hallux valgus surgery, although small between-group differences may not have been detectable given the relatively small sample size. Magnesium screws appeared safe with no allergic reactions or wound complications and may offer added benefits of not interfering with advanced imaging, decreasing the need for hardware removal and likely easier revision surgery. Level of Evidence: Level II, randomized controlled trial.
