Division of Paediatric Orthopaedics
The division looks after all aspects of paediatric orthopaedics, which has changed dramatically in the recent two decades. Problems that were once prevalent, like tuberculosis and poliomyelitis, are now uncommon. Instead we now see a wide variety of diseases, none of which is prevalent except for developmental problems like flatfoot and intoeing. A holistic approach is practised in caring for these young individuals with orthopaedics problems. There are also significant advances in fields like computerised gait analysis in cerebral palsy, and limb lengthening and reconstruction, which demands constant service review and research.
In-patients are taken care of at The Duchess of Kent Children’s Hospital (DKCH) and Queen Mary Hospital, while out-patients are seen at DKCH. Specialist clinics cover neuromuscular, fracture, congenital hand, leg length discrepancy and juvenile rheumatoid arthritis.
To keep pace with advances in paediatric orthopaedics, we have developed a gait analysis laboratory which is ‘ constantly upgraded with latest technology. We perform gait analysis for patients ranging from cerebral palsy, myelomeningocele and leg length inequality to cervical myelopathy. Our division also pioneered the use of selective dorsal rhizotomy and botulinum toxin injection for the treatment of cerebral palsy patients in Hong Kong. We also practise state-of-the-art limb lengthening surgery for patients with limb length discrepancy, limb deformity and dwarfism.
Despite the relatively small size of the division and heavy clinical load, we feel that active pursuit of research is of vital importance in maintaining good clinical practice and advancing our understanding of paediatric musculoskeletal problems. Apart from the clinicians, our research effort is supported by an overseas fellow, postgraduate students and research assistants.
