What causes scapular notching?
What causes scapular notching?
Results. Scapular notching after reverse total shoulder arthroplasty is due to repetitive contact between the polyethylene of the humeral component and the inferior scapular neck during adduction, leading to erosion of the scapular neck, polyethylene wear, joint inflammation, and potential implant loosening.
How do you stop a scapular notching?
Scapular notching may lead to deterioration of functional outcomes and glenoid implant loosening and failure. Lateral offset, inferior glenosphere overhang, and careful consideration of the presurgical glenoid morphology may help prevent scapular notching.
What is notching of the shoulder?
Scapular notching is a radiographic finding, which may occur following reverse total shoulder arthroplasty (rTSA). The term is used to describe an erosive lesion of the axillary border of the scapular neck that occurs when the medial rim of the humeral implant contacts the scapula during shoulder adduction.
How long is shoulder reversal surgery?
Surgical Procedure This procedure to replace your shoulder joint with an artificial device usually takes about 2 hours. Your surgeon will make an incision either on the front or the top of your shoulder. He or she will remove the damaged bone and then position the new components to restore function to your shoulder.
Where is the neck of the scapula?
The neck of the scapula is the slightly constricted portion which surrounds the head; it is more distinct below and behind than above and in front.
Is reverse shoulder replacement a major surgery?
Typically, reverse shoulder replacement is an elective surgery, which means that a person chooses to have it. Most people who choose to undergo reverse replacement have both: Significant shoulder joint damage, often from either osteoarthritis or rheumatoid arthritis.
How long does it take to fully recover from reverse shoulder replacement?
Recovery from Reverse Total Shoulder Replacement You will have outpatient physical therapy to strengthen your shoulder and improve flexibility. You should be able to eat, dress and do most daily activities within the first week after surgery. Full recovery usually takes up to four months.
What muscles elevate the scapula?
The elevation is accomplished by the trapezius, levator scapulae, and rhomboid muscles. Depression is accomplished through the force of gravity and the actions of the latissimus dorsi, serratus anterior, pectoralis major and minor, and the trapezius muscles.
What muscle runs from your neck to your shoulder blade?
The levator scapulae muscle is attached at the top four cervical vertebrae (C1 to C4) and runs down the side of the neck to attach at the top of the shoulder blade (scapula). This muscle helps with lifting the shoulder blade, bending the neck to the side, and rotating the head.
How long is the hospital stay for a reverse shoulder replacement?
You will stay in the hospital for one to two nights If you are planning to go to an extended care or rehab you will likely need to stay three nights due to insurance reasons. If you are planning to go to one of these facilities you may want to research places in your area before your surgery.
What is scapular notching in reverse shoulder arthroplasty?
Background: Scapular notching, erosion of the scapular neck related to impingement by the medial rim of the humeral cup during adduction, is a radiographic sign specific to reverse shoulder arthroplasty (RSA). Its clinical and radiological consequences remain unclear.
When does scapular notching occur after reverse Tsa?
Scapular notching is defined as glenoid neck erosion caused by repetitive mechanical abutment of the humeral component with the inferior scapular neck. This complication typically occurs within the first few months after reverse TSA [7].
What are the factors that cause scapular notching?
The incidence and severity of scapular notching is related to prosthetic design and surgical technique. Implant design factors include size, shape, and position of the glenosphere, inclination of the humeral neck-shaft angle, implant offset, and native scapular anatomy.
Is there a connection between impingement and notching?
This connection between impingement and notching, while implied in prior studies, has not previously been directly shown in a clinical population. Scapular notching is frequently observed following rTSA, although its etiology is not well-understood.
