Humeral Fractures Orthopaedia The humeral shaft is defined as the diaphyseal region of the bone, spanning from a point distal to the insertion of the pectoralis major muscle and proximal to the supracondylar ridge. the proximal portion of the humeral shaft is cylindrical. more distally, the shaft narrows and tapers to a triangular shape with the apex anterior. The proximal humerus comprises four “parts”: the greater tuberosity, the lesser tuberosity, the humeral head and the humeral shaft. fractures in this area are common, especially among older patients. among elderly patients with osteoporotic bone, low energy falls are the most common mechanism of injury; younger individuals sustain fractures.
Humeral Fractures Orthopaedia 23. low energy trauma and frailty. 24. pediatric fractures of the upper extremities. 25. pediatric fractures of the lower extremities. 26. fractures of the growth plate. 27. Proximal humerus fractures. proximal humerus fractures are common fractures often seen in older patients with osteoporotic bone following a ground level fall on an outstretched arm. diagnosis is made with orthogonal radiographs of the shoulder. Summary. humeral shaft fractures are common fractures of the diaphysis of the humerus, which may be associated with radial nerve injury. diagnosis is made with orthogonal radiographs of the humerus. treatment can be nonoperative or operative depending on location of fracture, fracture morphology, and association with other ipsilateral injuries. The proximal humerus comprises four “parts”: the greater tuberosity, the lesser tuberosity, the humeral head and the humeral shaft. fractures in this area are common, especially among older patients. among elderly patients with osteoporotic bone, low energy falls are the most common mechanism of injury; younger individuals sustain fractures.

The proximal end of your humerus is the top. the distal end is the bottom. so, if you have a proximal humerus fracture, your upper arm bone is broken near its top — the end that connects to your shoulder. similarly, if you have a distal humerus fracture that means your bone is broken at the bottom, closer to your elbow. Vast majority. high energy trauma in younger population. 3 main loading modes: compressive – humeral head impacts at glenoid. bending – angular forces at surgical neck. tension – rotator cuff pulling on greater and less tuberosities. fall on outstretched hand. valgus impacted proximal humerus fracture.
