Mr Daniel Perry

Daniel PerrySubspecialty: Hip surgery

Dan Perry leads research within the orthopaedic team and holds national grants and awards. He completed a fellowship at the Toronto Hospital for Sick Kids.

Mr Perry joined Alder Hey with a prestigious NIHR Clinician Scientist award, enabling him to develop research both within Liverpool and nationally. He is employed by the University of Liverpool as a Senior Lecturer, and is is part of the Institute of Translational Medicine, which has musculoskeletal disease as a core focus. He has a PhD in Epidemiology, focusing on Perthes’ disease of the hip.

Clinically, he has particular clinical interests in hip diseases and trauma. He has undergone broad surgical training in Merseyside, Warwick and fellowship training from SickKids, Toronto, Canada.

Mr Perry has published over 50 peer-reviewed papers, and several textbook chapters. For his research has been awarded both the Hunterian Professorship by the Royal College of Surgeons of England, and the Robert Jones Gold Medal from the British Orthopaedic Association.

Mr Perry sits on the methodology committee for the Bone and Joint Journal, and is a reviewer for the NIHR EME programme, the Bone and Joint Journal and Acta Orthop.

Research Activities

Mr Perry undertook a PhD investigating Perthes’ disease of the hip. This was largely concerned with investigating the causes this enigmatic disease. The results demonstrated some intriguing geographic patterns of disease throughout the UK, with far more disease in the North of the UK compared to the South.

Mr Perry then moved to the University of Warwick to be an NIHR Clinical Lecturer, where he particularly had great exposure to Clinical Trials with mentorship from Prof Matt Costa and Prof Damian Griffin amongst others.

Mr Perry now is focusing his efforts on forming comprehensive cohorts in children’s orthopaedics across the UK. It is hoped that this will both directly inform clinical practice, and provide sufficient knowledge from which to develop future clinical trials. This is funded by NIHR, with collaborations from the University of Oxford and a strong network of childrens orthopaedic surgeons from around the UK.

Other ongoing work is using national databases to investigate epidemiology, and service delivery in orthopaedic surgery. Ongoing projects include the use of CPRD, Scottish ISD Data, HES, NHFD and TARN.
