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. The research could help hospitals, surgeons and patients to choose what hip implant to use for replacement surgery.
Delayed admission of patients with hip fracture from the emergency department is associated with an increased mortality risk and increased length of hospital stay
The aims of this study were to assess whether delayed admission from the ED influenced mortality risk, length of acute hospital stay, risk of developing delirium and return to domicile for patients presenting with a hip fracture.
Optimizing Knee Positioning During Arthroscopic Knee Surgery
In this Technical Note, we propose an approach to improve the existing knee positions using a metal round stool as a foot support. The method aims to reduce reliance on human assistants during knee arthroscopy procedures and restore the natural positioning of leg muscles, potentially improving procedural outcomes.
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.
