We measured a cross-section of able-bodied (AB) men (n = 175) and men with chronic spinal cord injury (SCI) (n = 33) residing in the community, 14 to 65 years old, to identify associations between dietary factors, physical activity, health status, and mechanical properties of long bones assessed by phase velocity measurement of flexural waves in the tibia during the second to seventh decades. T...

DOI 10.3109/17453674.2014.942587 We present a case of bilateral medial tibia stress syndrome (MTSS) in a 500to 800-year-old male skeleton with an estimated age at deat...

Periosteal osteosarcoma is a rare subtype of osteosarcoma. Wide surgical removal is the commonly used treatment-method algorithm. However, the limb-salvage procedure of periosteal osteosarcoma in the distal tibia is a technical challenge to orthopedic surgeons because of the scarcity of soft tissue and subcutaneous nature in the anteromedial aspect. We encountered a 16-year-old female patient w...

Recently, 3-T magnetic resonance imaging (MRI) has been introduced for bone imaging. Through higher signal-to-noise ratios, as compared to 1.5-T MRI, it promises to be a more powerful tool for the assessment of cortical and trabecular bone measures. The goal of our study was to compare MRI-derived cortical and trabecular bone measures to quantitative computed tomography (QCT)-derived bone miner...

BACKGROUND Reduction of the tibia relative to the femur with the knee in maximum extension is required to correctly position the tibial tunnel in the sagittal plane when using a guide that targets the intercondylar roof. The authors found no studies that determined (1) whether gravity reduces the tibia and (2) whether roof impingement is prevented without a roofplasty and without positioning th...

OBJECTIVES To define pQCT precision errors, least-significant-changes, and identify associated factors for bone outcomes at the radius and tibia in children. METHODS We obtained duplicate radius and tibia pQCT scans from 35 children (8-14yrs). We report root-mean-squared coefficient of variation (CV%RMS) and 95% limits-of-agreement to characterize repeatability across scan quality and least-s...

PURPOSE Although bilateral lower-limb lengthening has been performed on patients with achondroplasia, the outcomes for the tibia and femur in terms of radiographic parameters, clinical results, and complications have not been compared with each other. We proposed 1) to compare the radiological outcomes of femoral and tibial lengthening and 2) to investigate the differences of complications rela...

Birds have a distally reduced, splinter-like fibula that is shorter than the tibia. In embryonic development, both skeletal elements start out with similar lengths. We examined molecular markers of cartilage differentiation in chicken embryos. We found that the distal end of the fibula expresses Indian hedgehog (IHH), undergoing terminal cartilage differentiation, and almost no Parathyroid-rela...

OBJECTIVES Assessment of additive impact of alfacalcidol 1 μg daily (Alfa) on bone mineral density (BMD) and on bone strength in postmenopausal women treated with alendronate 70 mg weekly + 500 mg calcium daily. SUBJECTS AND METHODS In a randomized, double-blind, placebo controlled study, 279 postmenopausal women with osteoporosis or osteopenia participated (intention to treat analysis [ITT];...

Although the biofidelity improvements of the pedestrian legform called the Flexible Pedestrian Legform Impactor (FlexPLI) relative to the conventional legform (EEVC legform) have been shown in past studies, their effects on the evaluation of safety performance of vehicles have not been clarified in a quantitative and comprehensive manner. The goal of this study was to clarify the diffe...
