The objectives of this study are to evaluate the impact of the CoVID-19 pandemic on the development of relevant emerging digital healthcare trends and to explore which digital healthcare trend does the health industry need most to support HCPs. A web survey using 39 questions facilitating Five-Point Likert scales was performed from 1.8.2020 – 31.10.2020. Of 260 participants invited, 90 participants answered the questionnaire. The participants were located in the Hospital/HCP sector in 11.9%, in other healthcare sectors in 22.2%, in the pharmaceutical sector in 11.1%, in the medical device and equipment industry in 43.3%. The Five-Point Likert scales were in all cases fashioned as from 1 (strongly disagree) to 5 (strongly agree). As the top 3 most impacted digital health care trends strongly impacted by CoVID-19, respondents named: - remote management of patients by telemedicine, mean answer 4.44 - shared data governance under patient control, mean answer 3.80 - new virtual interaction between HCP´s and medical industry, mean answer 3.76 Respondents were asked which level of readiness of the healthcare system currently possess to cope with the current trend impacted by CoVID-19. - Digital and efficient healthcare logistics, mean answer 1.54 - Integrated health care, mean answer 1.73 - Use of big data and artificial intelligence, mean answer 2.03 Asked if collaborative research in the form of digital data platforms for research data sharing and increasing collaboration with multi-centric consortia would have a positive impact on the healthcare sector, the agreement was high with a value of mean 4.10 on the scale. We can conclude that the impact of COVID-19 appears to be a high agreement of necessary advances in digitalization in the health care sector and in the collaboration of HCPs with the health care industry. Health care professional are unsure, in how far the national health care sector is capable of transformation in healthcare logistics and integrated health care.
This work features a new approach to overcome drawbacks of commercial calcium phosphate cements in terms of application by on-site preparation and bone ingrowth by introduction of macropores in the material using a hydrofluoroalkane based aerosol foam. The application of calcium phosphate bone cements (CPCs) into a void for example of an osteoporotic bone is very difficult as the cement paste is made outside the application site and subsequently applied into the damaged bone. A common drawback of especially apatitic cements is a very low resorption rate due to small pore size Therefore different approaches have been described to add macropores into the cement2, leading to bone ingrowth and tissue penetration. The aim of this project is the use of two separate formulations in pressurised systems – a suspension and an emulsion – which can be mixed in a specially developed device and can be applied easily and efficiently into a bone directly during surgery leading to a self-hardening macro porous CPC foam. The intention is to fill voids in osteoporotic bones to ensure stability for implants like e.g. screws for femur neck fractures. An increased stability for implants can allow the possibility of a less invasive femur neck preserving therapy in contrast to a femur neck replacement. Other indications for such foam (i.e. kyphoplasty) are under evaluation.Summary Statement
Introduction
Osteochondral injuries, if not treated adequately, often lead
to severe osteoarthritis. Possible treatment options include refixation
of the fragment or replacement therapies such as Pridie drilling,
microfracture or osteochondral grafts, all of which have certain
disadvantages. Only refixation of the fragment can produce a smooth
and resilient joint surface. The aim of this study was the evaluation
of an ultrasound-activated bioresorbable pin for the refixation of
osteochondral fragments under physiological conditions. In 16 Merino sheep, specific osteochondral fragments of the medial
femoral condyle were produced and refixed with one of conventional
bioresorbable pins, titanium screws or ultrasound-activated pins.
Macro- and microscopic scoring was undertaken after three months. Objectives
Methods
Bone shape variability within a specific population has been seldom investigated and used to optimize implant design. There is insufficient anatomical fitting of the existing prebend periarticular plates for the distal fibula. We developed a methodology for design of orthopaedic implants that fit a maximum percentage of the target population, both in terms of geometry and biomechanical stability. In co-operation with an implant manufacturer and different academic institutions, a virtual bone database has been developed that contains anatomical data of more than 1000 CT datasets with the implemented possibility to generate idealized implant fits for different anatomical sites. This program (Stryker Virtual Bone Database (VBD) is able to generate statistical anatomical shapes for different populations like age groups or ethnical groups. Based on this, an implant for the distal fibula has been developed (VariAx Distal Lateral Fibula Locking Plate) for distal fibula fracture treatment. Aim of this study was to develop and validate an implant that is optimized for the specific anatomical area. It should be precontoured and still fit to the majority of patients sustaining a distal fibular fracture. Another objective was to create a distally tapered design as there is less soft tissue cover in that anatomic area. ProE CAD system was used in combination with the Bone Database (VBDB) to evaluate the bone shape of the target population plate shape. Several bones (from CT scans) have been used in a first validation process in comparison with an implant already available on the market (SPS Fibula Plate). Additionally, the results have been verified with a bone fitting study which was conducted in collaboration with the Maurice E. Müller Institute (MEM) in Bern/Switzerland. In a second step, the finished implant design was validated against statistical bone shapes of populations of different ethical origin. The comparison of the new Plate's shape with real bone data confirmed that the neutral form does cope with the anatomic situation laterally which means that no systematic pre-bending of the plate is required. Comparing with a conventional implant, the new implant could have been implanted unbend in 6 of 7 cases of virtual matching with real patient datasets compared to none with the conventional implant. The validation of statistical datasets of different ethnical origin (Caucasian, Asian) showed no statistical difference of implant mismatch.Materials & Methods
