- Background. Excessive mortality and morbidity are serious problems after hip fracture in the elderly. Methods. Hip fractures in persons aged 50 years or older were prospectively registered in Japan in 2000. Questionnaires regarding both the first onset and the second 120-day period after hip fracture were obtained from 759 patients, 546 of whom were female and 213 male. Results. Their average age at the time of fracture was 80 years. Altogether, 68 people (9%) died within 120 days after fracture; and 25 patients died within 30 days. Those dying within 120 days and those alive after hip fracture were compared. By univariate analysis, risk factors were poor walking ability, need for a walking aid, low body mass index, history of falls, and lack of active exercise; however, none of these factors was identified as a risk factor by multivariate analysis. By multivariate analysis, the five risk factors associated with mortality were male sex, older age, high American Academy of Anesthesiology (ASA) grade, dementia, and residence in an institution. Conclusions. During the treatment and rehabilitation period special attention should be paid to patients with chronic diseases and reduced mental status.

- We analyzed the radiographic and clinical outcome of the ScanHip total hip arthroplasty in 70 patients after 10 years. The Swedish National Hip Register, in which the end-point of the survival analysis is defined as revisions, reported a 10-year survival rate of 94% with the ScanHip, but in the present series 13% of the femoral stems and 29% of the sockets met the criteria for aseptic loosening. Focal osteolysis was found around 8 sockets (11%) and 23 stems (32%) and had occurred significantly oftener around loose sockets, but not around femoral stems. Linear polyethylene wear was significantly increased in loose sockets, but no relationship was noted between polyethylene wear and stem loosening or was there a correlation between clinical symptoms or patients' satisfaction and component loosening. Therefore precise serial long-term radiographic follow-up is the only satisfactory method for detecting aseptic loosening of total hip arthroplasty. It gives the surgeon more detailed information about each case than survival analysis alone.
