关于客户
The customer in this case study is a 50-year-old woman who was diagnosed with a pseudotumor after Resurfacing Arthroplasty for osteoarthritis of the left hip joint. The revision failed after one year and she developed a pelvic discontinuity. Using conventional methods, the extreme bone loss would make it even more difficult to replace the prosthesis. The woman was able to carefully take her first steps completely pain free a few days after surgery. She is recovering extremely well, exceeding usual primary revalidation patterns.
挑战
The article discusses the challenges faced in hip replacement surgeries, particularly in cases where the patient has outlived the lifespan of the hip prosthesis, which is typically between 15 to 20 years. When a prosthesis fails, a revision surgery is carried out to replace the components. However, a significant challenge faced during implant revision surgery is that the pelvic bone stock is often significantly reduced. Ten-year failure rates of primary hip replacements are estimated at 11.4%. This number more than doubles to 25.6% in case of revisions. In over 58% of those revision failures, the acetabular component is involved. To deal with these challenges, a custom approach is most suitable.
解决方案
Mobelife, a Belgian high-tech company, has developed a completely customized approach based on Computed Tomography (CT) data by combining state-of-the-art image processing tools from Materialise and Abaqus FEA. The process begins with the creation of a 3D model of the patient’s pelvic bone based on CT images. Based on the CT-data, the bone is reconstructed automatically and the implant is designed in close collaboration with the surgeon for unique fit and functionality. The precise orientation of the newly created hip socket is anatomically analyzed. In cases of significant pelvic bone loss, the implant extends onto the major bones of the pelvis for fixation. A custom porous structure is used to fill the gap and a thin porous layer of titanium interfaces between the implant and the bone. Flexibility and compatibility are provided for either press-fit or cemented-liner integration.

Case Study
Hospital Inventory Management
The hospital supply chain team is responsible for ensuring that the right medical supplies are readily available to clinicians when and where needed, and to do so in the most efficient manner possible. However, many of the systems and processes in use at the cancer center for supply chain management were not best suited to support these goals. Barcoding technology, a commonly used method for inventory management of medical supplies, is labor intensive, time consuming, does not provide real-time visibility into inventory levels and can be prone to error. Consequently, the lack of accurate and real-time visibility into inventory levels across multiple supply rooms in multiple hospital facilities creates additional inefficiency in the system causing over-ordering, hoarding, and wasted supplies. Other sources of waste and cost were also identified as candidates for improvement. Existing systems and processes did not provide adequate security for high-cost inventory within the hospital, which was another driver of cost. A lack of visibility into expiration dates for supplies resulted in supplies being wasted due to past expiry dates. Storage of supplies was also a key consideration given the location of the cancer center’s facilities in a dense urban setting, where space is always at a premium. In order to address the challenges outlined above, the hospital sought a solution that would provide real-time inventory information with high levels of accuracy, reduce the level of manual effort required and enable data driven decision making to ensure that the right supplies were readily available to clinicians in the right location at the right time.

Driving Digital Transformations for Vitro Diagnostic Medical Devices
Diagnostic devices play a vital role in helping to improve healthcare delivery. In fact, an estimated 60 percent of the world’s medical decisions are made with support from in vitrodiagnostics (IVD) solutions, such as those provided by Roche Diagnostics, an industry leader. As the demand for medical diagnostic services grows rapidly in hospitals and clinics across China, so does the market for IVD solutions. In addition, the typically high cost of these diagnostic devices means that comprehensive post-sales services are needed. Wanteed to improve three portions of thr IVD:1. Remotely monitor and manage IVD devices as fixed assets.2. Optimizing device availability with predictive maintenance.3. Recommending the best IVD solution for a customer’s needs.

Harnessing real-time data to give a holistic picture of patient health
Every day, vast quantities of data are collected about patients as they pass through health service organizations—from operational data such as treatment history and medications to physiological data captured by medical devices. The insights hidden within this treasure trove of data can be used to support more personalized treatments, more accurate diagnosis and more advanced preparative care. But since the information is generated faster than most organizations can consume it, unlocking the power of this big data can be a struggle. This type of predictive approach not only improves patient care—it also helps to reduce costs, because in the healthcare industry, prevention is almost always more cost-effective than treatment. However, collecting, analyzing and presenting these data-streams in a way that clinicians can easily understand can pose a significant technical challenge.
