![]() ![]() Because the scapula is protected by the chest and surrounding muscles, it is not easily fractured. This study reported a rare case of catastrophic failure of a titanium locking plate. Cause Fractures Fractures of the clavicle or the proximal humerus can be caused by a direct blow to the area from a fall, collision, or motor vehicle collision. The most frequently fractured site of the humerus especially in elderly is the surgical neck which is an area of constriction distal to the tuberosities. The right surgery at the right time Mayos approach to these fractures depends on such factors as the patients age, bone quality and source of injury. Background Angular stable locking plates have shown good clinical results in treating proximal humeral fractures, but complications are not uncommon. Attached to the lips of the intertubercular sulcus are the tendons of the pectoralis major (lateral), latissimus dorsi (medial), and teres major (most medial/posterior). Symptoms include pain, swelling, and a decreased ability to move. It can occur after a normal fall or trip. The tendon of the long head of biceps brachii runs through this groove. A proximal humerus fracture is a break of the upper part of the bone of the arm (humerus). Mechanism and Epidemiology The proximal humerus is one of the most commonly broken bones in older people. ![]() The intertubercular sulcus or groove separates the two tuberosities. The greater tuberosity is given additional management considerations given the concerns regarding even minimal (3- to 5-mm or greater) displacement as this can lead to a significant compromise in patient outcomes following injury via impingement and rotator cuff dysfunction. The humeral head articulates with shallow glenoid fossa of the scapula which allows for complex dynamic range of motion in many different planes. The anatomical neck can be identified as the fused epiphyseal plate which is obliquely directed and lies proximal to greater and lesser tubercles. ![]() Other osseous elements that are relevant to proximal humeral anatomy include the bicipital groove/intertubercular sulcus, medial calcar, and insertion sites for the deltoid, pectoralis major, and latissimus dorsi muscles. ![]()
