Intramedullary fibular graft and quadricortical plate fixation in atrophic non-union of the osteoporotic humerus
Fractures of the humerus account for approximately 5—8% of all fractures. Most humerus fractures heal uneventfully, but whennon-unionoccurs, it is incapacitating for thepatient, and challenging forExpand
