MYHIP WORKFLOW PRECISION ON DEMAND 1. Medacta receives the CT images of the patient‘s leg. 2. MyHip preoperative planning commences with the 3D reconstruction of the joint following the surgeon’s preferences. 3. Virtual positioning of the implant is proposed to the surgeon, who can modify this planning, if required. 4. Once the planning has been validated by the surgeon, the 3D printing in-house manufacturing process starts.

Challenges in Total Hip Replacement (THR) include: • TO ASSIST THE SURGEON WITH IMPLANT SELECTION AND POSITIONING through a COMPLETE 3D PREOPERATIVE PLANNING and 3D PRINTED PATIENT-SPECIFIC GUIDES. • Dislocation prevention[1,2] • Leg length discrepancy assessment[3,4] • Femoral offset restoration[5] • Cup positioning to avoid edge loading[6] • Impingement analysis[7] • Range of Motion assessment[7] The MyHip system has been designed to assist the surgeon with implant selection and positioning[8] , addressing these challenges and streamlining the pathway to a carefully planned procedure,...
