Obesity and osteoarthritis are complex diseases to which multiple interacting factors contribute. The moderate association between obesity and knee joint osteoarthritis reflects the amplification by obesity of role of joint loading in the development and progression of osteoarthritis. However, joint loading is insufficient to explain the disparities between the incidence of knee OA in obese peo...

  Background: Little is known about the influence of habitual participation in physical exercise and diet on upper-extremity physical function in older adults. To assess the relationship of general physical exercise and diet to upper-extremity physical function and pain intensity in older adults.   Methods: A cohort of 111 patients 50 or older completed a sociodemographic survey, the Rapid Asse...

Lower extremity trauma is extremely common and accounts for almost 15% of emergency room visits,1 with 492,000 tibia, fibula, and ankle fractures per year in the United States.2 Acute injuries are commonly managed primarily by orthopedic surgeons with fracture fixation or stabilization. In complex fractures involving the lower limb, as in Gustilo grade IIIB or IIIC fractures, limb salvage typic...

Diagnostic ultrasound techniques used in the evaluation of the musculoskeletal system are rapidly evolving. Conventional B-mode and Doppler ultrasound imaging methods are workhorses in the diagnosis and treatment decision making for traumatic and pathologic conditions of joints, tendons, muscles, ligaments, and peripheral nerves. Recently developed sonoelastography techniques enable the qualita...

statistically and found to be of little value in reliably determining the presence or absence of DVT. The differential diagnosis for leg pain and swelling includes lymphedema, chronic venous insufficiency, infection (cellulitis), aneurysm, pseudoaneurysm, Baker cyst, and other musculoskeletal causes. Diagnosis of DVT depends on the clinician’s pretest probability assessment and a combination of...

Eight to 12 million people in United States have PAD (Allison et al. 2007). Only ~10% of patients with PAD have classic intermittent claudication (IC), ~50% have atypical leg symptoms and ~40% are asymptomatic (Hiatt 2001). Its prevalence significantly increases with age; 12 – 20% of those above the age of 65 years suffer from PAD (Ostchega al. 2007). The prevalence of PAD is similar in men and...

Lower extremity musculoskeletal injuries have become a public health concern for active individuals when considering the complications that often present later in life after injury (eg, degenerative joint disease). 10 A recent surge of lower extremity injury prevention programs, 14,22 specifically aimed at ACL injury prevention, have provided some promising results in reducing knee injury among...

BACKGROUND To assist in the treatment of gait disorders, an inverse and forward 3D musculoskeletal model of the lower extremity will be useful that allows to evaluate if-then scenarios. Currently available anatomical datasets do not comprise sufficiently accurate and complete information to construct such a model. The aim of this paper is to present a complete and consistent anatomical dataset,...
