The advantages offered by surgical planning tools and personalized guides and implants are applicable to a vast variety of surgical treatments. Some of these benefits have already been raised by the Getting It Right First Time (GIRFT) program in the UK.
Surgeons would need to make 50% fewer changes to AI-based pre-operative plans compared to current ones. This is according to a research project we conducted here at Materialise with Dr. Raf De Vloo, an orthopedic surgeon at AZ Klina in Belgium, in which we applied AI-based planning to 193 cases. This technology learns an individual doctor’s preferences for surgical approaches and, based on those, provides higher-quality pre-operative plans.
Dr. Ola Wiig, an experienced pediatric orthopaedic surgeon, was confronted with a very challenging deformity in a young teenager. Dr Wiig’s patient was suffering from severely reduced mobility as a result of an epiphysiolysis in her proximal femur, which caused her leg to be severely rotated outwards. This wasn’t just causing the patient pain, it was stopping her from being a normal teenager.
From x-ray-based pre-operative planning and templating software to patient-specific solutions which employ 3D technologies, orthopaedic surgeons have access to an array of software and services to assist them when planning for successful surgical outcomes.
30-year-old Partiban from Malaysia was an avid futsal player until he started noticing pain in his left knee throughout one year. The pain worsened until he had difficulties squatting and running; it eventually caused him to stop playing futsal. The patient was referred to Prof. Dr. Azhar M. Merican, who deduced that the underlying cause for the pain was a deformity of the patient’s left upper tibia. The deformity was due to the malunion of a fracture sustained in a motor vehicle accident when the patient was 14 years old. At the time, the fracture had been treated with a plaster cast.
German patient Inge W. had been afflicted with a hip malformation since her birth. Due to an extensive number of intense surgeries and revisions throughout her life, there was very little bone left in her pelvic region, leaving a large hole in the bone and making it very difficult to attach a standard hip implant. As her condition grew worse, it seemed that Inge had no other choice but to be confined to a wheelchair for the rest of her life. Fortunately, she was able to walk again with the help of a patient-specific 3D-printed hip implant.
Temporomandibular joint ankylosis, or the fusion of the jawbone, is most often the result of an injury or infection, and it prevents the patient from opening their mouth properly. It can only be treated with surgery, but due to the complex nature of the operation which presents a lot of risks for the patient, surgeons are often too careful to really perform an effective surgery. This means that the problem isn’t solved properly and is in danger of recurring.
Both surgical planning and medical 3D Printing are providing surgeons with more options for the surgical treatment of hip patients. With complex hip revision surgery in mind, we recently organized a webinar to present the range of planning and patient-specific surgical solutions offered by Materialise. These include X-ray based planning, 3D-printed anatomical models, and patient-specific surgical guides and implants. We also refer to this as the Materialise Hip Continuum.
