About complex hip surgery

A free educational resource for surgeons, patients and technologists.

During the past decade ComplexHipSurgery.com has evolved out of our experiences of working practice, into a comprehensive educational resource for surgeons, patients and technologists.

It began as a face-to-face international surgical course run by professor Alister Hart and Johann Henckel. Professor Hart has been a consultant orthopaedic hip surgeon since 2006 and in 2009 was nicknamed the “hip detective” by the BBC for his work on treating painful hip replacements. This website is a collection of cases involving Professor Hart’s patients with hip problems. 90% of his NHS referrals are from other consultant orthopaedic surgeons to him at the Royal National Orthopaedic Hospital NHS Trust. He also receives private referrals from GPs, physios and other surgeons to him at Cleveland Clinic London.

Over the years a whole range of new technologies have been incorporated into the care complex hip problems. Today, Professor Hart uses 3-D imaging to plan every operation. By doing this homework before the operation he is able to take on more complex cases with greater certainty of an excellent outcome. He uses 3-D printed models to assess the complexity before the operation, 3-D printed Guides to position the implants optimally and 3-D printed implants when the shapes are complex and he wants to minimise removal of bone.

We hope this resource will help you better understand the causes, treatment options and technology used to treat complex hip problems and return patients to active and happy lives.

Prof. Alister Hart

Alister is the UCL chair of orthopaedics and a consultant hip surgeon. He leads a research team of surgical technologists, based at the UCL Stanmore Campus & RNOH NHS Trust, focused on Implant Science and Surgical Imaging Technology, with Running for Science being a key project.

Alister has pioneered the use of 3D printing for hip surgery, robotic surgery and the analysis of orthopaedic implants. His research on implant science has led to changes to international health policy; development of clinical guidance in the UK and abroad; changes to clinical practice and subsequent cost savings.

Alister trained at Caius College, Cambridge, then Guy's and St Thomas' and the RNOH. He has published his work in more than 180 papers (first or last author on >100) with 200 co-authors, including the journal Nature. These papers have had >4000 citations and an h index of 37. He has been Principal Investigator on 26 grant awards since 2006 with total funding of more than £7 million from research councils (EPSRC and MRC), Innovate UK, Technology Strategy Board, NIHR, charities and industry.

Alister Hart supervises PhD and iBSc students and is leader for clinical modules at UCL musculoskeletal science and physical rehabilitation courses. He has convened, organised and financed seven international meetings held at the Wellcome, The Royal College of surgeons and the Royal Society of Medicine.

Mr. Johann Henckel

Johann is an orthopaedic surgeon with research interests in developing imaging software solutions to aid the understanding of the biomechanics of the lower limb musculoskeletal system. His research includes surgical technology applied to hip and knee joint replacement with expertise in the field of robotics and computer assisted surgery. 

Dr. Anna Di Laura

Dr. Anna Di Laura is an orthopaedic engineer with a background in biomedical engineering (BEng, MSc, PhD). She is the RNOH Implant Imaging Fellow and honorary Associate Professor at UCL. Her current research is aimed at a better understanding, through medical image computing, surgical planning and assessment of outcome, of how to improve hip function in humans; in patients with hip problems and also those with hip replacements.

Dr. Martin Belzunce

Dr. Martin Belzunce is an engineer with a PhD in image processing. His research interests are the basic science and translation of novel medical image processing methods into medical applications. In recent years, he has focused on image processing for musculoskeletal applications, where he has developed novel tools to automate and enhance the quantitative analysis of muscle health from MRI.
