Brachioradial joint

The glenohumeral joint (HRJ), also known as the acromioclavicular joint or coracoid joint, is one of the most commonly injured joints in the upper extremity. It will connect two very important structures of the human body: the shoulder and the arm. This joint plays a key role in movement



The shoulder is one of the most mysterious structures in the human body. The *humerus* is the largest and heaviest among all human bones. The shoulder has an articulation with the superior edge of the head of the humerus (the head of the humerus at the border with the neck), which is shaped like a slightly flattened spheroid: it is inserted into the opening of the acromion of the scapula (the upper flat part of the scapula). At the top of the shoulder is the largest joint - the **humeral joint.**
