Patient-specific Anatomical Models


Patient-specific 3D anatomical models are created from patients’ radiological examination (computed tomography and magnetic resonance tomography) images using special certified software. Anatomical models can be used in two forms: virtual anatomical models (for example, virtual models used in in pre-surgical planning software), or actual anatomical models which are materialized using additive manufacturing technologies.

Use of patient-specific anatomical models in clinical practice

  • Patient-specific anatomical models are used as a base for designing patient-specific implants and patient-specific surgical guides. They are used as a surgeon-manufacturer communication tool during pre-surgical planning, when the surgeon defines requirements for the design of a patient-specific implant and proceed to the validation of the design. More detailed information about the design of patient-specific implants and pre-surgical planning here.
  • Patient-specific anatomical models are also used as an assistive device when planning surgeries during which an implant is not applied. They allow assessing the topology of anatomical surfaces, the location and the ratio of pathological structures compared with healthy tissues. Using these models, surgeons plan intervention procedures, identify the potential challenges and anticipate their solutions.
  • When sterilized, patient-specific anatomical models are used during surgeries for the visualization of the surgical plan, as well as for training purposes. The use of patient-specific anatomical models as a tool for visualization of the surgical plan, decreases the duration of surgery and its invasiveness, which in turn decreases the risk of complications and the treatment as well.
  • Patient-specific anatomical models are widely used in medical universities to introduce residents rare clinical conditions and severe pathologies.
  • Patient-specific anatomical models are a mean for communication between surgeon and patient; surgeon presents the patient his/her pathology, explains the prepared treatment and obtains patient’s approval for it. Patients who have an opportunity to physically touch and see their own anatomical structure model from every angle possible, get better understanding of their pathology, the purpose of planned surgical procedures and chosen treatment plan.

Manufacturing and materials of Ortho Baltic patient-specific anatomical models

Ortho Baltic may present patient-specific anatomical models in three realizations:

    • In virtual form (in 3D pdf file format or as programme files: .STL, .PLY, .IGS, .OBJ, .CLY formats that can be uploaded to pre-surgical planning software). Virtual models are usually used for pre-surgical planning using specialized software;
    • Manufactured, using biocompatible material Nylon-12 (PA 2200) and additive manufacturing technology SLS. Such models may be used not only in pre-surgical planning, but also during surgery. In this case, they are delivered to the healthcare institution clean and packaged, prepared for sterilization in the autoclave.
    • Manufactured using plaster and additive manufacturing technology Ink-Jet. Thanks to the Ink-Jet technology, such models are made multi-coloured in order to obtain more detailed visualization of the anatomical model. However, the plaster is not biocompatible and the models made from it cannot be used in the operating theatre. They are usually used for educational purposes only.
