Spontaneous bilateral humeral head fractures occurring simultaneously in a woman with rheumatoid arthritis.

A 67-year-old woman with a 15-year history of seropositive rheumatoid arthritis developed acute night pain in both shoulders. Examination revealed bilateral swelling and joint mobility impairment. Ultrasonography disclosed joint effusions which were hemorrhagic on aspiration.

Influence of the reamer shape on intraosseus pressure during closed intramedullary nailing of the unbroken femur: a preliminary report.

The generation of intramedullary pressure during reaming of the femur was compared for two different reamer systems: the AO/ASIF universal reamer and the Gray flexible reamer system (Howmedica), while reaming in 9 oncologic patients undergoing prophylactic nailing of metastatic femora as indicated by impending fractures (unbroken femora). An intracranial fibre optic catheter pressure-monitoring device inserted through the distal supracondylar cortex was used to perform measurements. Preliminary data are presented.
