Complications of orthopedic implants are serious. There are as many as 20 million cases of bone trauma in China each year, 79.35% of which require surgical treatment, and more than 2.89 million operations are performed. Most of them are empirical planning and manual techniques, which may cause up to 21% of the implant positioning inaccurate surgery. The main reasons for the failure of the operation are: local bone density and implant strength cannot be confirmed before the operation; osteoporosis causes the implant to loosen easily; low bone strength increases the internal fixation segment, causing complications and high surgical costs; orthopedics The internal plant does not match the bone strength. The clinical lack of personalized treatment system for the elderly society. Elderly bone fracture takes a huge personal toll and social burden, but the current prevention method of osteoporotic fracture, as a golden diagnosis method, dual-energy x-ray absorptiometry (DXA) fails to effectively assess bone fracture risk, the clinical cinerary rate is less than 5.5% and the proportion of fractures attributable to osteoporosis (based on a standard definition of osteoporosis) is modest, ranging from 10% to 44% based on the most commonly used definition of osteoporosis (BMD T-score < -2.5). 

To deal with this issue, based on our more than 20-years research experience in the area of osteoporosis mechanisms, we have a series of research and experimental findings in pathology, medical imaging, and biomechanics of osteoporosis and osteoporotic fracture. Therefore, we are developing a systematic clinical approach to assess elderly osteoporotic bone fracture risk. With a multidisciplinary team of experienced computer vision and image processing scientists, biomedical engineers, mechanics scientists and clinicians with a good track record of deep collaboration, the objectives are:
1. Develop a software for clinical practice on precise bone radiomics and biomechanical analysis of osteoporotic fracture risk by machine learning and image processing techniques;
2. Invent a novel patentable BMD phantom-less method for osteoporotic fracture risk evaluation by Localized BMD and radiomics biomarker analysis, and further improve the accuracy and sensitivity of the system.

We prefer the candidates who have the background on: 
1. Research background:Computer/ electronic information engineering /mathematics , master degree or above
2. Familiar with C++/Python.
3.Software libraries: Familiar with OpenCV ITK, VTK, Scikit-learn
4.Publish journal papers/conference articles ( CVPR/ICCV/ECCV/SIGGRAPH/NIPS/ICML) (Prefer).

Professor WWJ Lu, Department of Orthopaedics and Traumatology

William W Lu, PhD, is Professor and Chairman of Departmental Research Postgraduate Committee of Department of Orthopedics and Traumatology, The University of Hong Kong. In 1995, he founded the Orthopaedic Research Centre, and has been honoured as one of the top 1% of scholars in medical engineering from 2009-2018 by ISI’s essential science indicators. In 2013, he was selected as Ng Chun-Man Professor in Orthopaedic Bioengineering. Prof Lu is also the Chief Scientist at Chinese Academy of Sciences and Honorary Professor of Faculty of Engineering, The University of Hong Kong.

His research interests are digital orthopaedics, biomechanics, biomaterials and the application of biomaterials for musculoskeletal degenerative diseases. He has been invited as visiting professor and speaker on multiple occasions to international meetings to lecture on these topics, and he has published more than 200 papers in top scientific journals with H-index = 53. Prof Lu sits on the editorial board of some top orthopaedic research journals such as JBMR. He is the past Chairman of BME Division, The Hong Kong Institution of Engineers. He is member of the Biology and Medicine Panel of the Research Grants Council of Hong Kong to October 2021. Professor Lu has consistently secured significant funding for innovative research, including more than HK$47 million in Hong Kong and $RMB20 million in PR China from a number of major funding bodies, such as National Key R&D Program of China, National Natural Science Foundation of China.
