President’s Message

Greeting from President

President, Japan Shoulder Society

Shinji IMAI

(Dept. of Orthop. Surg., Shiga Univ. of Medical Science)

I am Imai from the Department of Orthopaedic Surgery, Shiga University of Medical Science, and I was appointed as President of the Japan Shoulder Society in October 2024. Since the Japan Shoulder Society became a general incorporated association in 2014, I was appointed as the sixth president after the first president Eiji Itoi, the second president Kazuya Tamai, the third president Yozo Shibata, the fourth president Hiroyasu Ikegami, and the fifth president Hiroyuki Sugaya. In 2024, the Japan Shoulder Society celebrates its 50th anniversary, marking it as the world's oldest association of shoulder surgeons. To commemorate this milestone, the 50th-anniversary journal has been published. I am deeply honored and humbled to contribute to the legacy of such a historically significant Society.

The Japan Shoulder Society has been promoting education and research on cutting-edge medical technologies and discoveries in collaboration with related academic societies in Japan, such as the Japanese Orthopaedic Association, in order to achieve the objective of “Toward the advancement and dissemination of shoulder joint medicine to contribute to people’s welfare.” Shoulder surgeons in Japan have witnessed two major innovations over the last 20 years. One is shoulder arthroscopy around 2000. Another is reverse shoulder arthroplasty that was introduced in 2014, followed by the increasing use of anatomic shoulder arthroplasty. These two medical innovations form the backbone of clinical practice for modern shoulder surgeons.

Dr. Hiroyuki Sugaya, the fifth president, is a global pioneer of shoulder arthroscopy. During his presidency, collaborations between the Japan Shoulder Society and various overseas academic societies advanced significantly, promoting globalization of the Society. Under the fourth president Hiroyasu Ikegami, former congress president of the Japanese Society for Fracture Repair, the Society made great strides in the clinical application of reverse shoulder prostheses, particularly for fractures, in cooperation with the Japanese Society for Fracture Repair.

Assuming the position of the President of the Japan Shoulder Society, I have identified two challenges. One is to strengthen the Society. After the COVID-19 pandemic, prices steeply increased due to destabilized international affairs and inflation in the United States, etc., but this revealed the weak financial base of the Japan Shoulder Society. Expanding membership is essential for strengthening the Society. I believe that we must establish a healthy and stable financial foundation by reevaluating various financial matters.

Another is revitalizing the Society. While some may consider the Japan Shoulder Society to be already active, many disease guidelines have been developed in other orthopedic areas, while no guidelines have been developed for shoulder joint diseases. I think it is important to foster an environment where our Society can take the initiative in developing such guidelines.

In addition, while aging of the population is inevitable in the future of our country, the Japan Shoulder Society has not been frequently involved in prevention and treatment of osteoporosis, frailty and locomotion syndrome. The Japan Shoulder Society may be able to play an active role in medical care for the elderly and nursing care through diagnosis, surgical methods, subsequent physical therapy of osteoporotic proximal humerus fracture, among other areas.

I would also like to increase the number of female members to expand the Society’s size and develop new opportunities for their success. Opportunities for not only female doctors but also female physiotherapists and occupational therapists have not been sufficiently explored, and it may be necessary to create such opportunities for female members to energize our organization.

In conclusion, there are many issues for the Japan Shoulder Society to tackle, and I am committed to making every effort to promote the Japan Shoulder Society and to enhance the benefits it provides to its members. Your continued support is greatly appreciated.

History of Japan Shoulder Society

In June 1974, the first orthopedic symposium on the shoulder in Japan was held as a part of the 47th meeting of the West-Japanese Society of Orthopaedics and Traumatology (President: Prof. Nahoto Takagishi). In the symposium, the special speakers, Dr. Nagao Adachi, Professor Akira Iwabuchi, Dr. Hisao Endo, and Dr. Katsuya Nobuhara, called upon Prof. N. Takagishi to establish a Japan shoulder society. During the 43rd meeting of the Central Japan Association of Orthopaedic Surgery & Traumatology, the first meeting of the Shoulder Forum organized by Dr. T. Endo was held on October 18, 1974, in which 10 papers were presented with 87 participants. The second meeting of the Forum organized by Dr. Kiyohiko Oda was held on October 29, 1975 as a part of the 45th meeting of the Central Japan Association of Orthopaedic Surgery and Traumatology. The third meeting was held on November 4, 1976. It was organized by Prof. N. Takagishi with 35 papers and 186 participants. From this meeting on, the conference was organized as an annual meeting. Prof. Koukichi Tsuchiya was appointed as the president for the fourth meeting of the JSS, and also entrusted to the task of forming an organizing committee, drawing up the regulations, and issuance of journal, in consultation with Prof. Takagishi, the former president. In its first meeting on January 14, 1977, the organizing committee resolved, in addition to the regulations and issuance of journal, that the secretariat be placed in the Department of Orthopaedic Surgery, Faculty of Medicine, Fukuoka University. The Japan Shoulder Society, originally established in 1974, has the oldest foundation in the world as a specialized society focused on the shoulder.
