T o improve midfacial soft-tissue sagging, it is sometimes necessary to release the zygomatic and upper masseteric retaining ligaments in the sub-superficial musculoaponeu-rotic system (SMAS) plane. Release of these ligaments needs to be done carefully to avoid any injuries to the branches of the facial nerve. Some of the zygomatic branches run toward the zygomaticus major muscle and are locate...

On the basis of earlier reported data on the in vitro kinematics of passive knee-joint motions of four knee specimens, the length changes of ligament fiber bundles were determined by using the points of insertion on the tibia and femur. The kinematic data and the insertions of the ligaments were obtained by using Roentgenstereophotogrammetry. Different fiber bundles of the anterior and posterio...

The mechanism of orthodontic teeth movement is not entirely explained. The principal reaction on tissues at the cellular and molecular level is initiated by the force applied to the tooth crown and transferred in turn upon the periodontal ligament (PDL). It seems, therefore, that the PDL and particularly its properties play a key role in bone remodelling. One of the more commonly used methods, ...

Gross anatomy of the fetlock joint of the seven male adult onehumped camels were studied. In present study, the tendinous middle interosseous muscle, interdigital intersesamoid and straight sesamoid ligaments were observed. However, there was no proximal interdigital ligament. In conclusion, we found that the gross anatomy of the ligaments in one-humped camel fetlock joint share remarkable simi...

Ligaments are regularly subjected to repetitive loading in vivo. Typically, mechanical studies focus on repetitive loading protocols of short duration, while those characterizing damage accumulation over a longer duration (i.e., fatigue studies) are lacking. The aims of this study were as follows: (a) to demonstrate that damage does accumulate in ligament tissue subjected to repetitive loading ...
