Hand Surgery

Relating to my clinical sub specialty in hand surgery, I have research focus on reconstruction and replacement in general.

JOINTS/BONES/LIGAMENTS: I have established local clinical databases for trapeiometacarpal joint total joint arthroplasty (N>1000) and wrist arthroplasty (N>50) joint replacement for assessment of implant fixation, function, survival and patient related outcomes. I have implemented new minimally invasive arthroscopic guided procedures for partiel wrist fusion and follow cases for safety assessment as well as research purpose. I have appled functional wrist kinematic assessment (dynamic RSA) as well as malunion visualization/grading (model mirroring) of radius and ulna maluion to be able to calculate precisely the needed reconstruction to recover normalized function. Patients are follow cases for safety assessment and research. Years of research in kinematics of the distal radioulnar joint and triangular-fibrocartilage (TFCC) lesions is the basis of this clinical-scientific research expansion.

Furthermore, I have helped initiate a national study to clarify the results of different surgical methods to treat scapholunate-ligament lesion.

AMPUTATIONS/NERVES: New products and new clinical recommendations in repair, reconstruction and rescue after nerve injury stress the importance of systematic patient follow-up and scientific sharing of results, which I have facilitated with establishment of local clinical databases. Following international visits, I have applied to both upper and lower extremities new clinical treatments for muscle reeinnervations and/or neuropathic pain for amputees and after iatrogenic or traumatic nerve lesions in terms of targeted muscle reinnervation (TMR) and regenerative peripheral nerve interface (RPNI). Likewise, results after arm prosthesis – osseointegrated and socket prostheses - are followed closely and data ensured in a database.


Musculoskeletal Imaging

My research expertise in muscoluskeletal imaging is broad and interdisciplinary and include experimental and clinical research targeting improvements in tribology, survival and function of joint prostheses including investigations of implant design, implant coatings, bone cements, polyethylene wear, pseudotumors, bone quality, and rehabilitation. Quantitative imaging modalities is the fulcrum of my applied methodologies and take in radiostereometry (RSA), dual-energy x-ray absorptiometry (DXA), computed tomography (CT), microCT (μCT), finite element analysis (FE), and motion capture. I use measures of periprosthetic bone density, bone histology, and bone metabolism (blood samples) including bone turnover markers to investigate bone quality in relation to implant migration and survival, and to evaluate treatment effects of bone anti-resorptive pharmaceuticals. Artificial Intelligence become more and more important in the analyses of the big data sets generated.


Activity, function and health economics

Patient function before/after conservative treatment and surgical intervention is assessed by activity (accelerometry) and gait/motion analysis (inertia measurement unit, motion capture) and patient reported outcome measures. I have worked with establishment of clinical patient pathways and and health economic evaluations in relation to change of treatment regimes.


Microdialysis, pharmakokinetics, population pharmacokinetic modelleing

Microdialysis is the instrument used for evaluation of pharmacokinetic concetration profiles as well as ischaemia and inflammation in different tissue compartments. In several experimental (laboratory and animal models) and clinical studies my research group have evaluated antibiotics and chemotherapeutics in relation to differet administration routes and drug dose.

We have established the optimal time for administration and re-administration of cefuroxime in relation to infection prophylaxis in hand surgery, foot surgery and spine surgery. In cooperation with KU we also work with an infected pig model.

Through international collaborators we establish population pharmacokinetic models, which can simulate changes in treatment regimes e.g. effect on tissue concentration with increasing pharmaceutical dose.



I conduct research at international level and have published several level 1 state-of-the-art randomized clinical studies. I have published >160 papers in an 15-year publication carreer with 28 publications in 2022 and currently 15 publications in 2020. The publication list is mainly first and last authorships, which reflects a high degree of involvement in all studies. I expect my publication commitment to stay constant in the next 5 years based on my research plan.



I am the head of two productive, well-established research groups that are well-known internationally for high-quality research and we have multiple international collaborators at top research intsitutions. Furthermore, I am responsible for continuing and reshaping a resilient orthopaedic research laboratory at Aarhus University Hospital towards new research areas aod focus.


The AutoRSA Research Group is an interdisciplinary research group formed and directed by me since 2014 with impetus in a big scale technology research project based at Aarhus Universit Hospital. I was chairman of the project steerings committee and project leader for development of dynamic RSA. I followed the Harvard Business School and Innovation Foundation Pasteur Program in a 1 year project leader education. The research group successfully developed an image-diagnostic platform for biomechanical evaluation of fixation and function of orthopaedic joint replacements based on dynamic RSA.

Furthermore the largest database in the world with clinical radiostereometry of hip and knee arthroplasty was established and continue to form the basis of new studies including predictions of implant survival and patient reported outcomes in relation to hip and knee arthroplasty surgery.


The research group currently consist of 1 professor (me), 6 clinical physicians in different sub-specialties (hip, knee, shoulder/elbow, hand, paediatrics, reconstruction), 3, 3 phd students, 3 research year student (2 post research year/1 application), 1 medical students and 1 project coordinator.


The activity in the group is high and focus is on software development, validation research and clinical research. Artificial intelligence is applied for for analyses of the big data.


The Microdialysis Research Group is an interdisciplinary research group formed in 2014. I have directed the group since 2017. The research group use microdialysis for assessment of drug pharmacokinematics with a specific focus on contentrations of antimicrobials in bone such as for surgical infection prophylaxis and treatment of bone infection. We have studied many diffent antimicrobial drugs as well as the effect of dose and way of administration in experimental pig models as well as clinical studies. The group also work on optimization of antineoplastic treatment with measurement of chemotherapeutics in target sites and healthy tissues such as for bone cancers (sarcoma) and peritoneal carconomatosis (gynecholocal cancers). We have a current focus for evaluation of local treatment application and on establishing pharmacokinetic models to simulate changes in treatment regimes.


The research group currently consist of 1 professor (me), 1 associate professor, 1 assistant professor, 10+ clinical physicians in different orthopaedic subspecialties (hand, hip, knee, shoulder/elbow, spine, tumor) and other specialties (infection, plastic surgery, microbiology, oncology, veterinary), 4 phd students (and 1 in application), 5 active research year students (2 official/3 post research year), and 1 laboratory technician.


The activity in the group is great with a strong drive for high-quality experimental and clinical studies and publications.
