Shoulder pain affects 1 in 4 adults
There are a number of issues that can cause shoulder pain, including osteoarthritis, rotator cuff injuries, fractures, rheumatoid arthritis or other inflammatory disorders, or osteonecrosis which impacts blood flow to the humerus.
Total shoulder arthroplasty deemed safe, effective for patients aged 80 years and older
Patients aged 80 years and older had low rates of perioperative mortality and reoperation after anatomic and reverse total shoulder arthroplasty, according to results published in the Journal of Shoulder and Elbow Surgery.
How to Avoid Shoulder Pain at Work
Long periods of physical work involving positioning the arms over the shoulder and excessive load on the shoulders are common direct causes of shoulder pain.
Elbow hemiarthroplasty and total elbow arthroplasty provided a similar functional outcome for unreconstructable distal humeral fractures in patients aged 60 years or older: a multicenter randomized controlled trial
Semiconstrained total elbow arthroplasty (TEA) is an established treatment for elderly patients with distal humeral fractures not amenable to stable internal fixation (unreconstructable). In recent years, there has been increasing interest in elbow hemiarthroplasty (EHA), a treatment option which does not entail restrictions in weight-bearing as opposed to TEA. These two treatments have not been compared in a randomized controlled trial (RCT). The aim of this study was to compare the functional outcome of EHA and TEA for the treatment of unreconstructable distal humeral fractures in elderly patients.
