INTRODUCTION Osteopenic or osteoporotic bone changes of proximal humerus may cause fracture or pull out of suture anchors during rotator cuff repair surgery[1], thereby compromising the success of repair. Dual energy X-ray absorptiometry (DXA) is the most popular technique to measure the general bone mineral density (BMD), especially at the hip and lumbar spine. However, there is wide variation...

Supracondylar fracture of the humerus in children may be associated with nerve and vessel injury (Thomas and Alpar 1987). Sometimes attempts at manipulative reduction are unsuccessful. Recent papers have discussed treatment of displaced fractures by traction (Worlock and Colton 1984; Piggot, Graham and McCoy 1986). We report four cases in whom the neurovascular bundle and the biceps tendon came...

Epidemiological and ecological studies on long bone non-unions (NU) are scarce, based different populations methodologies. The aim of this study was to produce a descriptive analysis the femur, tibia, humerus non-union epidemiology in Spain.Methods Data were obtained from Minimum Basic (Conjunto Mínimo Básico de Datos, CMBD) Hospital Discharge Database Spanish Ministry Health, according ICD9-CM...

Seventy patients who had sustained supracondylar fractures of the humerus as children were examined. Loss of carrying angle of the elbow occurred if the fracture was immobilized in a varus position during healing. Varus malalignment could have been obviated if comparative radiographs of the other elbow had been taken and the Baumann angles compared. Rotation and posterior displacement at the fr...

To predict neuromuscular disorders, we are interested in monitoring upper limb movements continuously using wearable sensors. Shoulder muscle coordination is complex and for those with neuromuscular disorders, this coordination often fails. As monitoring the entire kinematics of the shoulder complex is nearly impossible to do continuously, we propose to simply track the humerus and clavicle ang...

The triceps brachii (TB) is the only muscle that lies along the posterior humerus, and its role in elbow extension has been the topic of investigation for many decades. The TB research has also included subjects such as strength training, effects of aging, training adaptions, etc. The purpose of this paper was to review some of the more unique investigations regarding the functions of the human...

Supracondylar fractures of the humerus are the most common fracture pattern of the elbow in children. Severely displaced supracondylar fractures of the distal humerus in children are challenging problems. Many treatment methods have been described for the treatment of displaced supracondylar fractures of the humerus, however, it has not been reached a consensus for the choice of the treatment. ...
