Our program benefits from a mixture of exciting elements, from complex trauma cases presenting to the busiest Emergency Department in Singapore at Tan Tock Seng Hospital, to the holistic management of osteoarthritis for a chronic sufferer. There are also opportunities to be exposed to paediatric orthopaedics in our affiliated institutions.

Our vibrant learning environment is fostered through many activities such as:

  • Presentation of paper at Singapore Orthopaedic Association (SOA) meeting
  • SOA teaching sessions
  • Attendance at training events
  • Compulsory courses e.g. fracture fixation skills course, Upper and lower limb surgical exposure courses
  • Critical review of medical literature and submitting to peer-reviewed publications
  • Student teaching
  • Quality enhancement project participation
  • Audit session attendance
  • Morbidity & Mortality (M&M) round attendance/presentation        



During Year In Training 1 (YIT1), you will be involved in the following:

  • Care of patients with surgical and medical emergencies, multiple organ system trauma, soft tissue wounds, nervous system injuries and diseases, peripheral vascular injuries and diseases, and rheumatologic and other medical diseases;
  • Participation in the pre-, intra- and post-operative care of surgical patients 

Through these experiences, you will attain the following competencies:

  • Development of knowledge, attitudes and skills needed to formulate principles and assess, plan and initiate treatment of adult and paediatric patients with surgical and/or medical problems;
  • Experience in the care of critically-ill surgical and medical patients;
  • Development of an understanding of surgical anaesthesia, including anaesthetic risks and the management of intra-operative anaesthetic complications 

Assessment will be continuous and include summative and formative types. These will help develop your ability to interact with patients and peers as well as increase your acquisition of surgical skills. Some examples of assessment tools are listed below:
