Abduction and adduction are shoulder and hip movements that occur in the body's frontal plane—an imaginary line that divides the body into front and back halves. They're essential for stability and injury prevention in your shoulders, pelvis, and lower back.
Common types of shoulder surgeries include rotator cuff repair, total shoulder replacement, and arthroscopy for conditions like frozen shoulder or impingement syndrome. In general, these and other shoulder procedures help treat shoulder injuries by repairing or replacing cartilage, tendons and ligaments, muscles, and joints.
Possible reasons why your shoulder hurts vary, but where you feel pain can help narrow down the cause. Common causes include poor posture, bursitis, arthritis, muscle strain, or a pinched nerve.
Rotator cuff tears do not heal well with time. They tend to either enlarge or, at best, stabilize in size. The good news is that rotator cuff tears do not necessarily need to heal in order for the symptoms to resolve.
Pain between the shoulder blades is often due to muscle strain, which may result from lifting heavy objects, poor posture, or overuse. Other health issues can cause upper back pain, though, including acid reflux, disc problems, gall bladder disorders, or even a heart attack. Different disorders will cause different types of pain.
