Fractures of the humerus head

Fractures of the proximal humerus are commonly seen especially in the elderly population. High-energy trauma in young people can be distinguished from low-energy trauma in the elderly resulting from falls of a low height which are typically characterized by osteoporosis. A precise analysis of fractures is essential for a good understanding of the fracture and an individual therapy for which the LEGO-Codman classification provided by Hertel is recommended. Nonsurgical therapy is commonly performed and widely accepted not only for simple fractures. For osteosynthesis angular stable implants became the gold standard but are frequently associated with a high rate of complications some of which can be lowered by an improved surgical technique. Even today varus dislocated fractures are challenging, especially in combination with destruction of the medial column. In those cases where stable osteosynthesis can no longer be achieved arthroplasty is indicated. The clinical results of anatomic fracture arthroplasty are strongly related with correct ingrowth of the tuberosities. Reverse fracture arthroplasty may be considered but indications should be interpreted with caution and preferably used in patients older than 75 years.
