Our grouptakes clues from our clinical practice and translates them into researchwith wide-ranging themes. In order to share our research with theworld, we present at international conferences and submit papers tointernationaljournals, particularly on the diagnosis and treatment ofperipheral nerves, tendon rupture, arthritis, elbow disease, tenocytedifferentiation, and stenosing tenosynovitis.Research subjectOutlook for researchOutlook for students after graduationThe Lower Extremities Group at Shinshu University conductsextensive research on various disorders of the lower extremities (hip,knee, and ankle joints) and various studies on questions that arise indaily practice. In the area of the hip joint, research is being conductedinto the development of osteotomy guides to improve the accuracy ofacetabular osteotomies, pelvic dynamics and lower limb rotationalalignment before and after hip replacement surgery, and in the area ofthe knee joint, research into new techniques for anterior cruciateligament reconstruction and osteotomies. Through these studies, weaim to improve the effectiveness of treatment and increase patientsatisfaction.Research subjectOutlook for researchOutlook for students after graduation・ Study on imaging findings and postoperative results of peripheral neuropathy・ Study on postoperative results of stage 4 trapeziometacarpal osteoarthritis・ Cohort study of Obuse resident (Obuse study)・ Elucidation of the tenocyte differentiation and tenosynovitis onset mechanism・ Application of results from research to the practical treatment of patients・ New preventative measures against geriatric diseases, such as osteoarthritisof the hand and wrist・ The mechanism of tenocyte differentiation and onset of tenosynovitis can beapplied to the development of regenerative therapy and new treatment.Through research, you can deepen your knowledge of diseases related toupper limb surgery. Developing a keen eye for multifaceted phenomena will beuseful for future clinical practice and further research.· Development of new tibial osteotomies for improved outcomes after ACL reconstruction· Development of a new technique to preserve the remnant in ACL reconstruction.· Research on the position of the acetabular fossa as an indicator for THA· Development of a patient-compatible osteotomy guide for acetabular rotational osteotomy· Provide safe, minimally invasive, and high-performing artificial joint surgery · Aim to develop surgical techniques for ACL reconstruction that enable athletes an early and safe return to competition.Through the diagnosis and treatment of disorders in the lower extremities, you can cultivate broad skills that can be applied to a wide range of issues. We will strengthen our research in specific fields and simultaneously aim to conduct top-level research in a global context.21Wide range of research to improve patient’s quality of lifeTranslating Clues from Clinical Practice into the Research Field信州大学医学部医学科発行年月：２０２４年７月 発行：信州大学医学部
