Pediatric Surgery and Orthopaedics Research Group
Oulu Childhood Trauma and Sports Injury Study
Research unit: PEDEGO
Mr. Juha-Jaakko Sinikumpu (MD, PhD) is Professor in Pediatric Surgery. He has also a title of docent and subspecialty in pediatric orthopaedics and traumatology. He is official national examiner of Pediatric Surgery specialty (post-graduate degree) and Pediatric Orthopaedics and Traumatology subspecialty in Finland (one out of five examiners in Finland).
His main scientific interests are childhood trauma and sports injuries. His other important interests are pediatric surgical disorders. He is the leader of Oulu Childhood Trauma and Sports Injury Study group and the co-leader of Pediatric Surgery study group. Sinikumpu is a member of international study group of European Pediatric Orthopaedic Society (sports group) and a Finnish National Pediatric Orthopaedic study group. Sinikumpu has supervised two doctoral dissertations during 2020. Furthert, he is a principal supervisor of four doctoral dissertations (under preparation) and a secondary supervisor of one dissertation (under preparation) in University of Oulu Graduate School (UniOGS). He has supervised 11 Master’s thesis (MD) and been both a reviewer and opponent of doctoral dissertations in the University of Helsinki and University of Turku, Finland. He has evaluated a docent application and been an external reviewer of a national foundation (Switzerland). Sinikumpu is a Section Editor of the Scandinavian Journal of Surgery (SAGE), being in response of pediatric surgery, pediatric orthopaedics and traumatology, hand surgery and neurosurgery. Sinikumpu is the member of editorial board of Journal of Children Orthopaedics (Elsevier). He was named in the editorial board of Hand Therapy (SAGE Publishing in 2014-15). He has been a member of the editorial boards of Duodecim journal and Finnish Medical Journal. The group leader is the member of Finnish Society of Surgeons, Finnish Society of Pediatric Surgeons, Finnish Society of Pediatric Orthopedics (vice-chair), Finnish Orthopedic Association, Finska Läkaresällskapet, Finnish Medical Association, Duodecim Foundation, European Pediatric Orthopedic Society (EPOS) and European Pediatric Surgical Association (EUPSA). Sinikumpu has studied pedagogical subjects by 20 credit points and the studies of 15 more points are on-going (to be finished due 2021). He is working as chief physician and head of the unit of Pediatric Surgery and orthopaedics in Oulu University Hospital.
What do we do
Oulu Childhood Trauma and Sports Injury Study; Pediatric Surgery and Orthopaedic Research is a youthful and curious group of enthusiastic researchers. The main study areas are:
1) Epidemiology and changing trends in pediatric trauma
2) Early risk factors of pediatric trauma and pediatric surgical disorders from the time of pregnancy and neonathal period
3) Surgical treatment options in pediatric fractures and the role of biodegradable material in osteosynthesis
4) Short- and long-term outcomes of pediatric trauma by treatment performed
5) New innovations and treatment processes of pediatric surgery and orthopaedics
The research outcomes have been presented e.g. in the European Pediatric Orthopaedic Society’s annual meetings, Nordic Orthopaedic Federation’s annual meeting and numerous national meetings, such as Operative days and Orthopaedic and Trauma days. The research group has published their study reports in appreciated peer-reviewed journals e.g. in Bone and Joint Journal, Bone, Biomaterials, International Orthopaedics, KSSTA, Injury, BMC Musculoskeletal, European Journal of Pediatric Surgery, Acta Pediatrica, Acta Orthopaedica, Scandinavian Journal of Surgery and European Radiology journals.

Where are we headed
There are several main focuses in the sub-projects of the research group. The main goals concern the following issues:
1) Genetic explanatory factors, gestational risk factors and other potential early risk factors of fractures, other injuries and surgical/orthopaedic disorders.
2) Forearm shaft fractures and distal forearm fractures. New treatment options with biodegradable intramedullary nails and new treatment methods by using custom-made 3D-guides and implants. Technical issues of elastic stable intramedullary nailing and short- and long-term outcomes. Treatment of childhood wrist fractures.
3) Clavicle fractures and shoulder injuries. Surgical fixation vs. nonoperative treatment, given that surgical care has increased recently. Long-term outcomes of nonoperatively treated clavicle fractures with shortening and the effect of the previous fracture on shoulder girlde anatomy and function.
4) Adolescents' knee injuries. The changing incidences of ACL injuries and patellary displacement and their changing treatment; the comparison of different fixation and reconstruction methods. Short- and long-term outcomes and the recovery to physical activities.
In another Pediatric Surgery Study Group, co-led by Sinikumpu with his predecessor, professor Willy Serlo, the main research focuses are as following:
5) The long-term overall outcomes of the patients with operatively treated craniosynostosis. Biodegradable osteosynthesis material in cranioplasty operations and cranial distraction.
6) Congenital lung anomalies (e.g. cystic-adenomatoid malformation) and their later association with lung infections and maligniencies.
7) Surgical wound in children, by comparing different suture materials and by using the underpressure-care.
