Orthopaedic surgery is becoming increasingly common due to recent significant improvements in medical imaging, biomechanical modelling, and additive manufacturing. For the pelvis, surgical reconstruction using metal implants remains challenging due to the involvement of complex anatomical structures. In Kazakhstan, these operations are performed using typical implants. The purpose of the present work is to develop a spersonalised implant and its real application to work out the procedure and master the technology. This article describes all the relevant stages, from medical imaging to an accurate three-dimensional anatomical model of the implant. This described procedure can also be fundamental for virtual preoperative planning and the development of patient-specific incision guides.
