Clinical Trial on Patient-Specific-Instrumentation Assisted Lapidus Fusion for Hallux Valgus

Design of PSI: DICOM files will be imported into the Model Intestinal Microflora in Computer Simulation (MIMICS 21.0) 3D image processing software (Materialize, Belgium) for 3D rendering. The segmented bone images will be used for design of the computer-aided modelling (CAM) surgical jigs. 3D printing of PSI jig. PSI-assisted Lapidus Surgery.

exposure of the 1TMTJ via a 3-5cm medial longitudinal skin incision and capsulotomy. Freehand creation of the fusion surface with fluoroscopic assistance. Fixation of the Lapidus arthrodesis will be performed with two 3.5mm headless compression screws
