BACKGROUND Preoperative periarticular bone quality is affected by joint loading. The purpose of this study was to determine the periarticular bone mineral density of the knee joint of patients undergoing total knee arthroplasty, and whether the location of the load-bearing axis correlates with the measured bone mineral density. MATERIALS AND METHODS The bone mineral densities of the medial an...

Bone is integral to the pathogenesis of osteoarthritis (OA). Whether the bone area of the tibial plateau changes over time in subjects with knee OA is unknown. We performed a cohort study to describe this and identify factors that might influence the change. One hundred and twenty-six subjects with knee OA underwent baseline knee radiography and magnetic resonance imaging on their symptomatic k...

conclusions the fixator-assisted lengthening plate technique helps to maintain the stability and alignment at both sides of an osteotomy during tibial elongation. it allows the early removal of the external fixator immediately after lengthening is completed. this technique can be applied in children with open physes and in patients with a narrow medullary canal who are unsuitable for limb lengt...

Medial tibial stress syndrome (MTSS) is a common overuse injury of the lower extremity predominantly observed in weight bearing activities. Knowledge about the pathological lesions and their pathophysiology is still limited. Only a single study was found to have investigated tibial bone density in the pain region, revealing lower density in athletes with long standing (range, 5-120 month) MTSS....

BACKGROUND Total knee arthroplasty is a complex procedure aiming to relieve pain and improve function. It is critical to select prosthesis that best cover the bone surfaces. Ethnicity may affect fitness of the components mainly designed for Caucasian populations. This study aimed to evaluate morphometric features of proximal tibia in Iranian population. METHODS During 2013, 150 consecutive pa...

This study aimed to evaluate changes in tibial bone speed of sound (SOS) over time, in preterm and term infants during infancy, in addition to identifying factors influencing the development of tibial SOS during infancy. Preterm (n = 155) and term (n = 65) infants were enrolled in this study. Tibial bone SOS was measured using quantitative ultrasonography (QUS) on the left tibia of newborn infa...

INTRODUCTION Physical activity has been recommended to patients with knee osteoarthritis for improving their symptoms. However, it is still controversial if physical activity has effects on joint structures including cartilage volume. The aim of this study was to describe the associations between physical activity and performance measured 5 years prior and tibial cartilage volume and bone area ...

ewing's sarcoma is a relatively common malignant bone tumor that typically occurs in long bone diaphyses of adolescents and young adults of 10-30 years old. often times, all ewing's sarcoma of bone have radiographic abnormalities. diagnosis is usually delayed and can be misdiagnosed as osteomyelitis. bone to bone metastasis occurs, but soft tissue retro bulbar metastasis is rare. this...

background: several systemic factors and hormones are thought to regulate the fracture healing process. vitamin d has emerged as a compound or hormone that actively participates in the regulation of calcium homeostasis and bone metabolism. objectives: the aim of this study is to determine the serum changes in the level of vitamin d during the acute healing period of tibial and femoral shaft fra...

Open tibial shaft fractures are the most common open fractures, and many complications can occur. During the treatment period, infection leading to osteomyelitis was the most common complication. However, no consensus exists regarding the ideal management for such cases in the literature.The purposes of this retrospective study were to review the treatment of patients with chronic tibial shaft ...
