The current case report describes an adult male with an intracortical lipoma accompanied by cystic changes in the tibial diaphysis. To the best of our knowledge, intracortical lipoma in an adult tibia has not been previously described. An anteroposterior radiograph of the tibia revealed an osteolytic lesion on the diaphysis. Magnetic resonance imaging and computed tomography revealed that the l...

This article describes an extensile surgical exposure to the distal humerus that is suitable for complex fractures involving the articular surface and extending into the humeral diaphysis proximal to the radial nerve. This method combines 2 approaches: olecranon osteotomy and the lateral paratricipital approach. This combination allows an appropriate exposure of both the articular surface and t...

BACKGROUND Osteonecrosis of the femoral head commonly occurs in patients aged under 50 years. Because of a high rate of complications associated with joint replacement surgery in this population, surgical techniques, such as vascularized fibular grafting, have been devised in an attempt to salvage the femoral head. The purpose of this study was to investigate the use of bone scintigraphy to pre...

Mechanical stimulation is critical for bone architecture and bone mass. The aim of this study was to examine the effects of mechanical loads applied to the knee. The specific question was whether loads applied to the tibial epiphysis would enhance bone formation in the tibial diaphysis. In C57/BL/6 mice, loads of 0.5 N were applied for 3 min per day for 3 days at 5, 10, or 15 Hz. Bone samples w...

The purpose of the present study was to compare the effects of alendronate and alfacalcidol on cancellous and cortical bone mass and bone mechanical properties in ovariectomized rats. Twenty-six female Sprague-Dawley rats, 7 months of age, were randomized by the stratified weight method into four groups: the sham-operated control (Sham) group and the three ovariectomy (OVX) groups, namely, OVX ...

Fractures are common traumatic injuries that mainly occur in the metaphyses of long bones such as the proximal humerus, distal radius, and proximal femur. However, most studies of fracture repair processes have focused on the diaphyseal region. In this study, we compared the bone repair processes of the metaphysis and the diaphysis of the mouse tibia. Bone apertures were formed in the tibial me...

Discoveries of juvenile primary bone malignant neoplasm have been rare in archaeological settings. This study presents the first case as such from ancient China. An individual (M799) aged 14–17 years Dongxin cemetery Northern Wei Dynasty (386–534 CE), Datong, Shanxi Province, was found with signs neoplasm. The skeleton macroscopically examined aid computed tomography imaging. Results demonstrat...

The third metacarpal (MC3) bone, along with the proximal phalanx, is one of bones that are most prone to injury in sport horses. To date, no detailed analysis has been conducted would compare strength parameters bilateral MC3 taking into account differences depending on site measurement. aim study was between left and right horses at 10%, 20%, 30%, 40%, 50%, 60%, 70% 80% bone length using perip...
