Sarcopenia and Its Association With Change of Bone Mineral Density and Functional Outcome in Old-Aged Hip Arthroplasty Patients.

This study aimed to investigate the relationship between sarcopenia and change in bone mineral density (BMD) and functional outcome in hip arthroplasty patients. Among the 221 patients who had undergone hip arthroplasty, 147 patients were enrolled. All patients were divided into 2 groups according to presence of sarcopenia.

Outcomes of Wedge Wing in the Lag Screw for Unstable Intertrochanteric Fractures in Elderly Patients.

Purpose: To evaluate clinical-functional and radiologic outcomes of elderly patients with an unstable intertrochanteric femur fracture treated with a wedge wing in the lag screw.

Materials And Methods: Forty-eight patients treated with the Dyna Locking Trochanteric nail (DLT nail) to resolve an unstable intertrochanteric femur fracture were reviewed retrospectively. Based on AO/OTA classification, Fracture 31-A2 (34 cases) and 31-A3 (14 cases) were included in the analysis.

The stages of physical activity and exercise behavior: an integrated approach to the theory of planned behavior.

This research aims to verify whether it is possible to explain the health-promoting behaviors based on sociodemographic characteristics by integrating the theory of planned behavior (TPB) proposed by Ajzen in 1988 and the transtheoretical model (TTM) proposed by Prochaska and DiClemente in 1983. In particular, the aim was to verify whether the variables of the TPB can properly distinguish the stages of change in exercise in the proposed integrated model and to figure out how attitude, subjective norm, perceived behavior control, influence, and intention-can explain the stages of change in exercise. Investigators who have taken previous training for the survey visited and interviewed 3658 people older than 30 years in the chosen town by multistage sampling method from July 27 to July 31, 2003.
