A 3-Arm Study on G7 Acetabular Cup With Echo BiMetric Stem in Total Hip Arthroplasty

The study is designed to compare three articulation options in terms of osteolysis, patient satisfaction, clinical and radiographic outcomes (Oxford Hip score (OHS) and Harris Hip score (HHS) and safety. In addition, the purpose of the study is also to evaluate the safety and effectiveness of patients who received G7 Acetabular system in conjunction with Echo BiMetric stem in primary total hip arthroplasty.

Prevention of Coronary Heart Disease in Morbidly Obese Patients

The changes in risks of developing coronary heart disease in patients with morbid obesity after different weight loss interventions have not been extensively studied. The primary objective of this study is to investigate whether an intensive lifestyle intervention program in a tertiary care clinic (Spesialsykehuset for Rehabilitering) is comparable with a 7-week low-energy-diet followed by bariatric surgery in decreasing the risk of cardiovascular disease in these patients.

Ultrasound Findings of Thumb Muscles in 1st Carpometacarpal Osteoarthritis

Carpometacarpal (CMC) joint osteoarthritis is a disorder that is estimated to affect more than one-third of postmenopausal women, leading to decreased muscle strength, reduced joint range of motion, and pain.The pathogenesis of thumb CMC osteoarthritis involves complex interactions between biomechanical forces, genetic predisposition, hormonal changes, repetitive microtrauma, and aging. An important factor in the progression of carpometacarpal osteoarthritis is the loss of joint stability provided by the surrounding muscles (2). The common methods for diagnosing thumb CMC OA is plain radiographs and clinical examinations. However, radiographs are unable to assess the role of surrounding structures, including muscles and ligaments. Ultrasound is a cost-effective, radiation-free, and easily applicable imaging method.
