Minimally invasive spine stabilization (MISt) is new concept of spinal surgical procedure, which represents stabilizing the spine with various minimally invasive techniques. MISt is typically applied to the patients with spinal instability and spinal deformity.
MISt includes various techniques such as MIS-PLIF/ TLIF, MIS-long fixation using percutaneous pedicle screw, lateral interbody fusion (XLIF/ OLIF/ DLIF), cortical bone trajectory (CBT), percutaneous vertebroplasty (BKP/VBS), interspinous spacer (X-stop, etc.), video-assisted thoracoscopic surgery (VATS), cervical/ lumber total disc replacement (TDR), posterior second sacral alar iliac screw insertion (S2AI), sacroiliac arthrodesis, and so on.
The Society for MISt was established in April 2009 at a meeting in Boston, MA, USA, by Koji Sato (Nagoya), Takanori Saito (Osaka), Masahiro Hoshino (Tokyo), Tsuyoshi Arizono (Fukuoka) and Ken Ishii (Tokyo). The Society for MISt is engaged in the following activities for propagation of safe MISt based on an “All-Japan” policy that transcends academic cliques and organizations:
1. Honne-kai (open discussions), 2. Clinical conferences, 3. Education of spine surgeons and other medical staff, 4. Training young lecturers to give seminars (MISt Ishin-no-kai), 5. Multicenter academic research, 6.International promotion, 7. Cadaver training support, 8. Development of new medical devices
Today, Society for MISt consists of 7 branch societies. The Kansai,Chugoku-Shikoku, Kanto and Kyushu MISt societies were established in 2012,followed by The Tohoku MISt society in 2013, and the Chubu MISt society andHokkaido MISt society in 2014. Now, Society for MISt is spreading in the world and the international branches will be established in 2016.
