Introducing Alfonso™ Cloud: A New Frontier in Convenience and Speed for Orthopaedic and Spinal Implant Testing

Alfonso™ Cloud is a self-service particle-based SaaS simulation platform for the orthopaedic and spinal implant industry. It dramatically reduces the time and cost of the implant testing process, setting a new “gold standard” for bringing new implants to market.

May 10th, 2023 – Today Lifespans, Ltd. ( announced the launch of Alfonso™ Cloud (, a self-service particle-based SaaS simulation platform for the orthopaedic and spinal implant industry.

Introducing Alfonso™ Cloud A New Frontier in Convenience and Speed for Orthopaedic and Spinal Implant Testing

The first of its kind in the industry, Alfonso™ Cloud is an online simulation portal that provides implant manufacturers with 24-hour access to its revolutionary Alfonso™ particle-based simulation technology. Since its introduction at AAOS in Q4 2021, Alfonso™ has rapidly grown in popularity, becoming trusted by R&D teams at five of the top-10 implant manufacturers by global revenue.

Going far beyond conventional computer modeling methods like FEA, Alfonso™ can provide extremely accurate models of material damage, such as during the loading of porous 3D-printed devices or implant subsidence in bone and foam.

Alfonso™ Cloud opens access to these powerful models to engineers at any company through a secure, dedicated online portal, allowing them to select from a growing library of standard ASTM tests – all backed by rigorous validation based on V&V 40.

Alfonso™ Cloud fully supports secure file upload along with the convenience of online credit card payment options. Engineers can view in real time the status of their simulation order with downloadable results available in 1-2 days rather than weeks or even months as with traditional testing methods.

The CEO of Lifespans, Sloan Kulper, Ph.D., said: “We focus on building software, but first and foremost we’re a team of biomedical engineers. We designed Alfonso™ Cloud to be exactly the tool that we would want when designing new implants: fast test results, affordable pricing, and a ton of validation data to support the models. Some of the best companies in the world use Alfonso™, and I’m thrilled to bring its benefits to a broader cross section of our industry with this unique online platform.”

About Alfonso™

Introduced in at AAOS’s annual congress in 2021 and already in use by many leading orthopaedic and spine implant manufacturers, Alfonso incorporates a ground-breaking “particle-based” computer model of bone tissue and bonelike materials, invented by its team of MIT engineers and world-leading orthopaedic surgeons from the University of Hong Kong. With findings published in the Journal of Orthopaedic Research, it is the world’s first simulation system capable of simulating the cracking and crushing of realistic trabecular bone structures – a key missing feature in conventional simulation that has been sought after for decades.

Through its new secure online portal,Alfonso™can complete same-day testing of joint recon, trauma, and spinal implants and rank their performance against predicates using validated industry-standard ASTM tests (F543, F1264, F2077, F2267, and more). Alfonso also understands the mechanics of cadaveric bone tissue and can easily test implant migration and cut-out in a wide range of validated osteoporotic and healthy adult bone fracture models.

After creating a free account, customers simply upload a 3D model of their device to our secure confidential Alfonso™ Cloud system, select which ASTM or cadaveric testing models to run, and Alfonso™does the rest. No prototyping or testing machine booking time needed!

“As an orthopaedic trauma surgeon, using computer simulated bone models is a great shortcut for me to test out my new implant design ideas quickly”, said Associate Prof. Christian Fang, FRCS, from the University of Hong Kong Faculty of Medicine (Dept. of Orthopaedics & Traumatology). “No more hassle is needed setting up lengthy hydraulic tests. Now it doesn’t matter that the biomechanics tester in the lab is occupied or out of service, now I can comfortably perform my tests from home.”

Paul Higham PhD., Senior Advisor to Lifespans Ltd. also said, “with four major implant manufacturers already using Lifespans’ technology in their implant development, Alfonso is on track to become the new standard for pre-clinical testing in the orthopaedic devices industry.”
