Proximal Humerus Fracture (Broken Shoulder) 肱骨近端骨折 Overview(概述) This condition is a fracture of the head of the humerus - the "ball" of the shoulder's ball-and-socket. 肱骨近端骨折是肱骨头部的骨折,肱骨头是肩膀球臼关节的...

These are often associated with fractures of the surgical neck and/or of the greater tuberosity of the proximal humerus. A good functional recovery is associated with a successful ...

Figure 1. Malunion below the tuberosities: a: anatomical structures of the proximal humerus, applied loads and potential resulting displacement: superior and posterior traction for the greater tuberosity (GT), medial traction for the lesser tuberosity (LT), anteroposterior and mediolateral tilt for ...
When fractured, the greater tuberosity tends to displace posterosuperiorly, the lesser tuberosity and the shaft displace medially, and the head may be pulled by the attached tuberosity, impacted into valgus, or in more severe cases dislocated, impacted, or divided. Internal fixation of two-part,...
Type A fracture: Non-displaced fracture of the proximal humerus account for 85% of all, more common in people over the age 60. Bandage or plaster suspended is suggested. Type B fracture: Common surgical neck and greater tuberosity avulsion fracture. Type C fracture: Common surgical neck fractu...
Greater tuberosity (GT) fractures of the humerus contribute to 14鈥 20% of all proximal humeral fractures (PHF) and provide considerable challenges because of their proximity to the rotator cuff, which may negatively affect shoulder function if left untreated. A 45-year-old man who had an ...
thought of as the major blood supply to the proximal humerus, this theory has since been debunked[21]. The AHCA does give off two main branches via the anterolateral ascending branch and the arcuate artery, with the latter serving as the major blood supply to the greater tuberosity[14]. ...
Introduction: The proximal humerus fractures involve head, greater tuberosity, lesser tuberosity and\nproximal one-fourth of the shaft. It has been estimated that proximal humerus fractures account for nearly\n4% of all the fractures and... Gnanesh,CK Rao,SD Roshan - 《Indian Journal of Orthopae...
For the displacements between the head and the greater tuberosity fragment, we found no differences between the two fixation systems, with both systems providing sufficient stabilization of the tuberosity. Migration of external fixator pins is a common complication, particularly with thin wire pins [22...
