Results published in the Journal of Bone and Joint Surgery found patients who underwent anatomic total or reverse shoulder arthroplasty had “significant and rapid” improvements in sleep disturbance after surgery.
A shoulder dislocation is an injury that occurs when the ball of the ball-and-socket shoulder joint is separated from its normal position. The ball comes out of the socket of the shoulder. When this occurs, the ball may stay out of the shoulder and need to be put back into place, or it can slide back into normal position on its own.
Calcific tendonitis is a common source of shoulder pain and can be a frustration given the severity of pain and the duration of symptoms. However, the news is not all bad! On a positive note, the vast majority of patients do find relief with nonsurgical treatments for this condition. In fact, studies have shown about 75 percent success with simple steps for treatment. While treatment often takes 3 to 6 months, there are typically improvements without having to undergo a surgical procedure.
Shoulder blade pain can have many different causes. Although you may assume you sustained an injury or simply slept in the wrong way, the pain might actually be related to your heart, lungs, spine, abdomen, or pelvis. In cases like these, the pain may be referred, meaning that a problem in one part of the body excites nerves that trigger pain in another part of the body, such as your shoulder blade.
Reverse shoulder arthroplasty (RSA) increases the moment arm of the deltoid, however there is limited knowledge on the accompanying changes in muscle architecture that play a role in muscle force production. The purpose of our study is to use a geometric shoulder model to evaluate the anterior deltoid, middle deltoid, and supraspinatus regarding 1) differences in moment arms and muscle-tendon lengths in small, medium, and large native shoulders, and 2) impact of three RSA designs on moment arms, muscle fiber lengths, and force-length (F-L) curves.
