We are currently running a study with the orthopaedic team at Alder Hey concerning hip dysplasia. Dan Perry, NIHR Clinician Scientist, Senior Lecturer University of Liverpool and Consultant Orthopaedic Surgeon set the following question “Can 3D printing replace an arthrogram for hip imaging?” Hip deformity is one of the most common outcomes following many paediatric hip diseases. Reconstructive surgery is frequently employed to improve the congruency of the hip, to prolong or obviate the time-to-arthroplasty.
Surgical decisions regarding reconstructive surgery can be challenging. A variety of imaging modalities can be helpful in guiding surgical planning. However, most of these modalities are static images, therefore they are not readily representative of the movements within a hip. An arthrogram is the most dynamic investigation offering a ‘tactile’ insight into the anatomical variants, however only offers two-dimensional
