Janssen TWJ. Effects of hybrid cycling on lower-body soft tissue composition, and proximal tibia and distal femur bone mineral density in inactive people with long-term spinal cord injury: a 16-wk randomized controlled trial. PLoS One. Abstract Objective: To investigate the effects of hybrid cycle exercise on soft tissue composition of the legs, proximal tibia and distal femur bone mineral dens...

Accurate femoral prosthesis press-fit is essential for successful Introduction: cementless total hip arthroplasty (cTHA) and dependent upon proximal femur size and geometry. Study objectives were to determine the variability of proximal femur size and geometry in primary cTHA patients and correlate them with patient demographics and body mass index (BMI). Medical records of 127 consecutive prim...

We quantified differences in trabecular volumetric bone mineral density (BMD) of the femoral head between patients with proximal femoral fractures and healthy subjects in the control group by using quantitative computed tomography (QCT) with the purpose of providing guidance for the choice of head screw in the intramedullary nail fixation. Participants suffering from intertrochanteric fractures...

INTRODUCTION Differences in the magnitude of bowing between races are well-known characteristics of the femur. Asian races have an increased magnitude of femoral bowing but most of the orthopedic implants designed for the femur do not match this exaggerated bowing. We calculated the sagittal and coronal femoral bowing in the Japanese population at different levels of the femur and addressed its...

We present a retrospective review of a single-surgeon series of 30 consecutive lengthenings in 27 patients with congenital short femur using the Ilizarov technique performed between 1994 and 2005. The mean increase in length was 5.8 cm/18.65% (3.3 to 10.4, 9.7% to 48.8%), with a mean time in the frame of 223 days (75 to 363). By changing from a distal to a proximal osteotomy for lengthening, th...

1. The mean attenuation coefficients of trabecular and cortical bone in the radius were measured in 32 female patients with fractured proximal femur, and in 28 age-matched female controls, with a special-purpose computed tomography-scanner. 2. The largest difference between the two groups was in the mean attenuation coefficients for trabecular bone in the distal radius. The mean value for fract...
