The extension synergy for the lower extremity includes hip extension, adduction and internal rotation, knee extension, ankle plantar flexion and inversion, and toe plantar flexion. [ 1 ] Note that some muscles are not usually involved in these synergy patterns and include the lattisimus dorsi , teres major , serratus anterior , finger extensors ...
Extension is the opposite of flexion, a straightening movement that increases the angle between body parts. [12] For example, when standing up, the knees are extended. When a joint can move forward and backward, such as the neck and trunk, extension is movement in the posterior direction. [ 10 ]
The rotator cuff muscles of the shoulder produce a high tensile force, and help to pull the head of the humerus into the glenoid cavity. The glenoid cavity is shallow and contains the glenoid labrum which deepens it and aids stability. With 120 degrees of unassisted flexion, the shoulder joint is the most mobile joint in the body.
Tenodesis grasp and release is an orthopedic observation of a passive hand grasp and release mechanism, affected by wrist extension or flexion, respectively.It is caused by the manner of attachment of the finger tendons to the bones and the passive tension created by two-joint muscles used to produce a functional movement or task (tenodesis).

In anatomy, flexor is a muscle that contracts to perform flexion (from the Latin verb flectere, to bend), [1] a movement that decreases the angle between the bones converging at a joint. For example, one's elbow joint flexes when one brings their hand closer to the shoulder, thus decreasing the angle between the upper arm and the forearm.
The Latarjet operation, also known as the Latarjet-Bristow procedure, is a surgical procedure used to treat recurrent shoulder dislocations, typically caused by bone loss or a fracture of the glenoid. The procedure was first described by French surgeon Dr. Michel Latarjet in 1954. [1]
A dislocated shoulder can be treated with: arthroscopic repairs; repair of the glenoid labrum (anterior or posterior) [1] In some cases, arthroscopic surgery is not enough to fix the injured shoulder. When the shoulder dislocates too many times and is worn down, the ball and socket are not lined up correctly.
A shoulder examination (or shoulder exam) is a portion of a physical examination used to identify potential pathology involving the shoulder. It should be conducted with both shoulders exposed to assess for asymmetry and muscle wasting.
