Crist, MD and Gregory J. Della Rocca, MD, PhD, (Harry Hoyen, MD and Stephen L. Kates, MD)Proximal humerus fractures are fragility fractures often seen in late middle-aged and older adults. A 65-year-old caucasian lady has a 5 threat of sustaining a proximal humerus fracture by the age of 90.249 Danger things for establishing proximal humerus fractures incorporate low bone mineral density, frequent falls, diabetes, difficulty walking in dim light, poor vision, and low dietary calcium intake. A proximal humerus fracture normally occurs immediately after a fall from standing height onto an outstretched arm or straight onto the shoulder. A careful history documents vital information and facts that may determine modifiable threat elements that led for the injury, including dizziness, recurrent loss of consciousness secondary to antihypertensive medication, or frequent falls resulting from a cluttered living atmosphere. An understanding with the patient's preinjury functional status, which includes rotator cuff function, medicalClassificationThe most frequently made use of technique for classifying proximal humerus fractures was described by Neer in 1970 (Figure 9).253,254 This method incorporates Codman four parts from the proximal humerus, namely, the anatomic head, the lesser tuberosity, greater tuberosity, as well as the humeral shaft (Figure ten).255 Displacement of greater than 1 cm or angulation from the component by 45 or a lot more makes it possible for the fragment to become counted as a part. Therefore, a nondisplaced fracture would be zero parts as well as a fracture with displacement of higher than 1 cm of all 4 parts will be a 4-part fracture. Also, the Neer classification has quite a few special proximal humerus fracture sorts, for example the fracture linked having a glenohumeral dislocation and one particular with splitting on the articularMears and KatesFigure ten. The popular zones of injury in the humerus, that may be, the anatomic head, tuberosity region, and surgical neck location.Figure 9.D) or displaced superiorly with articular surface in varus (varusdepressed) with apex anterior angulation inside the sagittal plane consequently in the pectoralis and deltoid forces around the humeral shaft. Head-splitting fractures, fractures exactly where the articular segment has much less than 8 mm of metaphyseal extension, and fractures with a disrupted medial calcar hinge place the vascular supply for the proximal humerus at risk of avascular necrosis (AVN) and could influence the treatment approach.251,252 Since a vascular necrosis from the proximal humerus can be nicely tolerated, it doesn't necessarily have to direct initial therapy.
