Ultrasound findings and prognosis of shoulder pain: a role for Doppler signal?

Purpose: To find ultrasound prognostic factors for shoulder pain. Methods: This was an observational, prospective study, comparing the evolution of ultrasound findings with clinical outcomes, in patients with shoulder pain. Data were collected in two appointments, from February 2018 to March 2021. Two-tailed non-parametric statistics were used, and p values <0.05 were considered significant. Results: A total of...

Local bone metabolism balance regulation via double-adhesive hydrogel for fixin...

The effective osteointegration of orthopedic implants is a key factor for the success of orthopedic surgery. However, local metabolic imbalance around implants under osteoporosis condition could jeopardize the fixation effect. Inspired by the bone structure and the composition around implants under osteoporosis condition, alendronate (A) was grafted onto methacryloyl hyaluronic acid (H) by activating the carbox...

Arthroscopic-Assisted Acromioclavicular Joint Dislocation Repair: A Modified Te...

Acromioclavicular (AC) dislocation is a common lesion often resulting from a sports injury. Nowadays, treatment is still controversial mainly in grade III lesions according to the Rockwood classification. For most surgically treated AC acute dislocations, treatment is performed with an arthroscopic procedure that anatomically reconstructs the coracoclavicular ligaments. Increasing knowledge about AC joint biome...

Primary stability analysis of stemless shoulder implants

Although the primary stability of joint implants is fundamental for successful osseointegration, little is know about this issue in the context of stemless shoulder implants. Considering 3D finite element models, the purpose of this study was to evaluate the primary stability of five stemless designs, based on the Sidus, SMR, Simpliciti, Eclipse, and Global Icon stemless systems. Three alternative bone quality ...

Bone remodelling of the humerus after a resurfacing and a stemless shoulder art...

Background: New implant designs, such as resurfacing and stemless implants, have been developed to improve the long-term outcomes of the shoulder arthroplasty. However, it is not yet fully understood if their influence on the bone load distribution can compromise the long-term stability of the implant due to bone mass changes. Using three-dimensional finite element models, the aim of the present study was to an...

Surgical Treatment of Rotator Cuff Tears After 65 Years of Age: A Systematic Re...

Introduction: The objective of this study was to analyze current evidence regarding surgical management of rotator cuff tears in patients of 65 years of age and above. Our hypothesis was that surgical repair of rotator cuff tears, in patients older than 65 years, conveys good outcome scores. We have not found a similar systematic review in current literature.Material and Methods: Medline®, PubMed, Scopus, and t...

β-Tricalcium Phosphate in the Surgical Treatment of Proximal Humeral Fractures

Introduction: The proximal humeral fractures are becoming more frequent, with a greater tendency for its surgical treatment by osteosynthesis with plate and locked screws. The mechanical and biological failure in these fractures and devices, despite the evolution of this type of implants, highlighted the synthetic bone grafts became an option.Material and Methods: Over a period of 96 months, patients considered...
