Brief Biography

Mr Bruce was born and educated in North Liverpool. He qualified in Medicine from Liverpool University in 1985.

He developed his interest in children’s orthopaedics after a student elective at the A. I. Du Pont institute in Delaware, USA.  Mr Bruce gained his FRCS(Eng) in 1987 and thereafter was trained in orthopaedics on the Liverpool orthopaedic training circuit. During his training he spent three months studying at Massachusetts General Hospital and a further six months studying children’s orthopaedics on the residency programme at Connecticut Children’s Medical Centre, USA. After completing his training in Stanmore, London as the National paediatric orthopaedic fellow Mr Bruce was awarded his CCST and took his consultant post at Alder Hey Children’s Hospital, Liverpool in 1997.

Mr Bruce presently holds office on the Executive of the British Society for Children’s Orthopaedic Surgery (BSCOS) and is the Treasurer of the North West Children’s Orthopaedic Group (NWCOG). He regularly lectures for BSCOS, NWCOG, and holds honorary Lecturer posts in Liverpool, Dundee and Edge Hill Universities. His practice encompasses the full spectrum of children’s orthopaedics and trauma with a special interest in paediatric hip and spine disorders.




Specialist in spinal deformity including scoliosis and kyphosis.


Brief Biography

Mr Davidson underwent surgical training on the Mersey Deanery rotation following graduation from the University of Leeds.  He completed his spinal surgical fellowship at RJAH Oswestry and Alder Hey Hospital, Liverpool.  He also completed a visiting spinal fellowship at Princess Alexandra Hospital and Mater Hospital, Brisbane, AustraliaMr Davidson was appointed as Consultant Spinal Surgeon to Alder Hey Children’s Hospital and RJAH Hospital in 2001. His specialises in spinal conditions including all aspects of spinal deformity including scoliosis & kyphosis. 




Mr Perry leads the research within the orthopaedic team, and holds national grants and awards. 


Brief Biography

Mr Perry holds 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 Clinical 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 60 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 BMJ, Nature Scientific Reportsm 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. The British Orthopaedic Surveillance Study is now active and recruiting children with Perthes' Disease (Legg-Perthes' Disease, Legg-Calve-Perthes Disease) and Slipped Capital Femoral Epiphysis (Slipped Upper Femoral Epiphysis, SCFE, SUFE). 

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.
