The field of orthopedics is involved in the understanding, diagnosis and treatment of the motor organs including bones, joints, muscles, ligaments and nerves within the limbs and body trunk, which are directly connected to the quality of day-to-day life.
At present, the authors are engaged in diagnosis and research based on the themes 1) Understanding the clinical condition of joint diseases, 2) Diagnosis and treatment of osseocartilaginous tumors, 3) Diagnosis and treatment of spinal disorders, 4) Sports injuries during physical development, and 5) Treatment of disease in the motor organs within a super-aging society.

The field of orthopedics is divided into various specialist areas. In this department we are not restricted to general orthopedic conditions, but rather accept specialist outpatient consultations regarding all orthopedic conditions, and aim to provide the highest standards of medical care.
In order to relieve our patients’ pain and functional disabilities, and return them to ordinary life as quickly as possible, we work to ensure mutual understanding between doctors and patients, and implement treatment based on this understanding and agreement.
