| Outline of Final Research Achievements |
In the greater tubercle of the humerus, the lateral impression that is composed of the border with the highest impression, the border with the middle impression, and the border with the lateral wall of the greater tubercle. In all samples of humeri with rotator cuffs, we could confirm the lateral impression, and the border between the highest impression and the lateral impression corresponded to the anterior border of the insertion of the infraspinatus tendon.
Regarding the tennis elbow, the extensor carpi radialis brevis(ECRB) simply originated as a tendon without any muscle, whereas other extensors originated as a mixture of tendon and muscle. At the anterior part of the ECRB origin, the thin attachment of the joint capsule lay deep to the ECRB and was distinct in comparison with the posterodistal portion. The anterior part of the ECRB origin was delicate, because the ECRB origin was purely tendinous, and the attachment of the articular capsule was thin.
