This year, our office in Japan opened a brand-new medical 3D printing facility in order to provide our customers in Japan with localized service for patient-specific surgical guides and anatomical models for orthopaedic and cranio-maxillofacial surgeries. But what does it take to set up a new production facility for highly regulated medical devices? We talked to our colleagues at the Japan office to find out.
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.
In a recent study in the Netherlands, all 12 patients who underwent an acetabular reconstruction of large Paprosky type 3 defects using the Materialise aMace custom acetabular cup, were recorded as being satisfied with the results of their procedure. The study, by Marieke Baauw, MD, Gijs Gerard van Hellemondt, MD and Maarten Spruit, MD, PhD from the Department of Orthopaedic Surgery at Sint-Maartenskliniek in Nijmegen, the Netherlands reported on their use of the aMace as part of an integral approach which included “a detailed approach to defect analysis, including measurement of bone deficiency and bone quality”. As reported in Helio Orthopaedics, the study presents positive results from a follow up of the 12 patients at least 18 months after surgery.
A five-year-old boy named Jojo from a village near Munich was diagnosed with a rare malignant tumor called Ewing`s Sarcoma. Usually found in the diaphysis (middle part) of long bones Jojo`s tumor was located in the distal part of his left femur and very close to the growth plate. Since tumor-endoprostheses are not available for such young children due to their small anatomical dimensions, an amputation or rotation plasty has to be performed in these cases.
Both high tibial osteotomy (HTO) and distal femoral osteotomy (DFO) procedures aren’t always straightforward and may require an alternative method to be adopted when planning for surgery. Innovative software and services are available to simplify the planning process and increase predictability of the surgical outcome.
RS Print recently took the leap and opened up a new office in Detroit, Michigan, for their subsidiary Phits. The result of a joint venture between Materialise and RS Scan, Phits specializes in 3D-printed, orthotic shoe insoles.
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.
The shoulder is a truly extraordinary joint, as it allows a full 180-degree range of vertical and horizontal motion. Unfortunately, the downside of this flexibility is that the more a joint can do, the more that can go wrong. The shoulder joint can wear out due to age, infection or trauma, leading to pain and a loss of function. When it comes to researching solutions to these problems, the shoulder surgeons at the Florida Orthopaedic Institute (FOI) and the researchers at the Foundation for Orthopaedic Research & Education (FORE) in Tampa, Florida, lead the way as one of the most reputable shoulder research collaborations in the world.
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.
American surgical device company DJO was having challenges prior to the launch of their new implant, the TaperFill™ Hip Stem, a shorter femur stem designed to be inserted through a direct anterior approach hereby sparing the critical posterior soft tissue. The design of the implant proved to be very tricky as it needed to fit closely in the cortical bone to ensure stability. As there was not much room for error, it was difficult to create a design that fit a maximum amount of patients, since every anatomy differs slightly from person to person. DJO optimized the hip with the help of image-based population analysis.
