Outline of Final Research Achievements

Long head of biceps tendon (LHBT) is originated from shoulder joint and run through anterior upper arm. Though LHBT has been recognized as a pain source of shoulder, its characteristics have not been clarified yet and showing various contribution among patients. In this study, we have developed a new human pain model using ultrasound-guided injection of hypertonic saline into LHBT, which demonstrated spreading pain distribution from anterior to posterior shoulder and approximately 30% reduction of shoulder abduction and elbow flexion force without any structural change of tendon.

Academic Significance and Societal Importance of the Research Achievements

腱板断裂は中高年の肩痛をきたす代表疾患であるが、その痛みにはLHBT由来の痛みが混在している可能性が高い。本研究の成果は、LHBT由来の痛みの広がり方や肩・肘の運動機能に与える重要性、および腱板修復術に際して痛みのためにLHBT切除術などの追加処置を行うことの妥当性、有効性を示唆するものである。
