PURPOSE To evaluate age- and gender-related mechanical properties and bone mineral density (BMD) of the proximal humerus at different levels and regions. MATERIALS AND METHODS Mechanical indentation testing, DXA, QCT, pQCT and the radiogrammetry (Cortical Index, CI) were carried out in 70 freshly harvested humeri from 46 human cadavers (23 females, 23-males; median age 70.5 years). RESULTS ...

ABSTRACT This is a report of a study on the long term results of PHILOS plating and percutaneous K-wire fixation in a prospective series of proximal humerus fractures in elderly patients. We reviewed a total of 60 patients with proximal humerus fractures in 30 patients (Group 1), who were treated by open reduction and internal fixation with Proximal Humeral Internal Locking System (PHILOS) plat...

P roximal humerus fractures are common, and about 80% are well managed nonsurgically. The remaining 20% present a therapeutic challenge because surgical stabilization is necessary to ensure healing and to optimize function. The priorities in surgical stabilization of proximal humerus fractures are (1) restoring the anatomic relationship between the tuberosities and the articular head fragment a...
