Hip implant study identifies materials with the lowest risk of needing revision
Hip implants with a delta ceramic or oxidized zirconium head and highly crosslinked polyethylene liner or cup had the lowest risk of revision during the 15 years after surgery, a new study led by the University of Bristol has found.
Soccer heading may cause more damage to the brain than previously thought
Heading is a widely used technique in soccer where the players control the direction of the ball by hitting it with their head. In recent years, research has been done that suggests a link between repeated head impacts and neurodegenerative diseases, such as chronic traumatic encephalopathy (CTE).
Estimating elbow loading conditions through the motion behaviors of subchondral bone density during joint movements
Evaluating complicated stress across the elbow under joint motion remains difficult. Here, we aimed to evaluate the distribution of the subchondral bone density in the normal elbow bones and further characterize their spatial relationships during elbow motion to estimate the loading stress across the articular surface using three-dimensional computed tomography bone models.
Subacromial Balloon Spacer for Massive Irreparable Rotator Cuff Tear is Cost-Effective in Older, Low-Demand Patients With Massive Irreparable Rotator Cuff Tear and Severe Comorbidities
The InSpace subacromial balloon spacer (Stryker, USA) is indicated for the treatment of massive irreparable rotator cuff tears. The device is placed in the subacromial space with the aim of restoring shoulder function by limiting painful acromiohumeral contact and recentering the superiorly migrated humeral head. However, controversy exists because two randomized controlled trials have produced conflicting findings with regards to efficacy.
Bottom-of-Foot Pain: Why It Hurts and How to Treat It
When the bottom of your foot hurts when you walk, it can be caused by many things, from ill-fitting shoes to activities like long-distance running or walking. For jobs that require long hours on your feet, bottom-of-the-foot pain is an occupational hazard.
