Tomohiro Shimizu教授の研究室は、レーザー治療や画像診断技術を応用した関節・骨・軟部組織の病態解明を柱としています。特にHR-pQCTを用いたリウマチ性関節炎の早期骨破壊のモニタリングや、膝関節の力学的変化と前十字靭帯再生術後の関節機能回復の関連性に関する研究が進んでいます。また、スポーツ障害や手術動画解析における画像認識技術の応用も展開されており、臨床的応用に直結する革新的な研究が特徴です。

Using HR-pQCT, our data suggest that anti-TNFα treatment prevents erosion progression and deterioration of bone microarchitecture within the first 3 months of treatment, one patient not responding to treatment, had significant progression of bone erosions within this short time period. Patients with low disease activity scores (<3.2) can have continuous HR-pQCT-detectable progression of erosive disease with MTX treatment only. HR-pQCT can be a sensitive, powerful tool to quantify bone changes an
The increased incidence of osteoarthritis (OA), particularly knee and hip OA, and osteoporosis (OP), owing to population aging, have escalated the medical expense burden. Osteoarthritis is more prevalent in older women, and the involvement of subchondral bone fragility spotlights its association with OP. Notably, subchondral insufficiency fracture (SIF) may represent a more pronounced condition of OA pathophysiology. This review summarizes the relationship between OA and OP, incorporating recent
Our data should be useful for analyzing pitching activity and clarifying the pathology of shoulder disorders associated with throwing.
Because of the adverse consequences of abnormal knee kinetics on anterior laxity after ACLR, efforts to improve knee movement patterns should be initiated.
Detecting surgical tools is an essential task for the analysis and evaluation of surgical videos. However, in open surgery such as plastic surgery, it is difficult to detect them because there are surgical tools with similar shapes, such as scissors and needle holders. Unlike endoscopic surgery, the tips of the tools are often hidden in the operating field and are not captured clearly due to low camera resolution, whereas the movements of the tools and hands can be captured. As a result that the
