  • Orthopedic Help to Children in Armenia, supported by Jinishian Memorial Foundation, 2002-2003.
  • Wheelchair Project, supported by Wheelchair for the World Foundation.
  • Teaching and clinical project to develop pediatric orthopedic services at the Iashvili Central Children’s Hospital in Tbilisi (Georgia).
  • Staff training in Balgrist Orthopedic Hospital (Zurich, Switzerland), Bern University Hospital (Bern, Switzerland) and Clinique du Parc (Lyon, France).
  • Hip ultrasound screening in some maternity hospitals in Yerevan since 2008. The aim of this project is early diagnosis of hip dysplasia in newborns and early treatment.
  • Since 2001 the STO initiated the spine surgery program in cooperation with the colleagues from the USA, France and Switzerland. The program includes clinical evaluation, bracing and the surgical treatment.
  • Intraoperative neuromonitoring, since 2012, in cooperation with Bern University Hospital. Neuromonitoring helps to decrease the risk of spinal surgeries and to perform more difficult operations on the spinal column.
  • Teaching project for specialists from different regions for hip ultrasound, supported by Jinishian Memorial Foundation, 2013.
  • Screening of neonatal (obstetric) brachial plexus palsy (NBPP): organization of early detection, diagnosis and rehabilitation and surgical treatment. The project of contemporary management of NBPP has commenced in 2010 in cooperation with experts of hand surgery from France, which helps many children to avoid the possible disability.
