Deltoid Muscle Anatomy and Function
The deltoid muscle is the main muscle of the shoulder. A triangle-shaped muscle, it helps move your upper arm and stabilizes the shoulder joint.
What causes pain in the right hip in females?
Possible causes of right hip pain include muscle injury, osteoarthritis, and pelvic floor conditions. In females, it can also occur during pregnancy. Treatment may involve pain relief, stretching, and exercise.
Readmissions more likely for wheelchair users after shoulder replacement
Wheelchair users are nearly three times more likely to experience hospital readmission following total shoulder arthroplasty (TSA), according to UT Southwestern Medical Center researchers. The findings, published in the Journal of Clinical Medicine, highlight the importance of comprehensive preoperative counseling and risk assessment for patients who use wheelchairs.
Causes and Treatment for Outer, Side, and Inner Hip Pain
There are many possible causes of hip pain. They include serious ones, like a fracture or joint infection, and less serious causes, like bursitis.1 Your healthcare provider can diagnose the cause and help to plan your treatment.
Impact of Reverse Shoulder Arthroplasty Design and Patient Shoulder Size on Moment Arms and Muscle Fiber Lengths in Shoulder Abductors
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.
