What is a bursal surface tear?
What is a bursal surface tear?
Bursal-sided tears tend to be primarily caused by subacromial impingement. Articular-sided tears usually result from trauma to a degenerated tendon. Intratendinous tears result from differential shear stress within the supraspinatus tendon.
What is bursal fraying?
Fraying occurs because of excessive force on the rotator cuff that increases the stress in the tendons and causes tears of the tendon fibers. This type of injury generally results in the acute onset of pain, swelling and limited mobility in the shoulder.
What is a high grade bursal surface tear?
Ellman grade III tears, which involve more than 6 mm or 50% of the tendon thickness, are also known as high-grade PTRCTs. Bursal-side tears typically occur in middle/older-aged patients (>40 years of age) as a result of intraarticular pathology or impingement and are less common than articular-side tears [5].
What is a high grade tear?
A high-grade tear means the fibers in the tendon are more than 70% torn. The surgeon recommended repair of the tendon with surgery. My elbow didn’t hurt, but it felt unstable and I didn’t have much strength in my forearm.
Is it possible for concrete to get scuffing?
Concrete surfaces are strong and durable, but that doesn’t make them impervious to scuffing. Like any surface, concrete can get scuffed, especially in high traffic areas. If you had concrete installed, your contractor should have given you detailed instructions to help you care for your specific concrete surfaces.
What is the purpose of scuff sanding concrete?
Scuff sanding is also the first step in preparing newly cured concrete for painting. Scuff sanding not only helps remove the old product, but it gives the concrete surface a slightly rough texture so new sealants can bond with the surface.
What causes bruising on the surface of unsound concrete?
Bruising occurs when microcracks form a network near the surface. The unsound concrete then crumbles away, exposing aggregate.
Do you need to scuff sand concrete before painting?
Concrete has a very porous surface. To protect it, homeowners often coat it with sealers or paint. When these products deteriorate and need replacing, you need to scuff-sand the concrete to remove them. Scuff sanding is also the first step in preparing newly cured concrete for painting.
