A 3D-printed screw mechanism as an alternative method to prevent wire migration in nonpalpable breast lesion localization.

ABSTRACT: Wire localization for nonpalpable breast lesions and pre-neoadjuvant chemotherapy (NAC) clips can lead to complications including wire migration, pneumothorax, and organ injury. This study evaluates the clinical efficacy and safety of a novel 3D-printed screw mechanism designed to prevent wire migration. This retrospective descriptive study included 104 patients with nonpalpable breast lesions and pre-NAC clips who underwent wire localization between March 2023 and August 2024. A screw mechanism was designed and manufactured using 3D printing technology with polylactic acid (PLA) material (4 g per device). The device features a 21.7 mm base diameter and elliptical wire hole (2.5 × 4 mm). Wire stability and complications were assessed through imaging and clinical follow-up. The median age w
