What is one of the potential causes of anatomic changes in the glenoid?

Arthritis is a potential cause of anatomic changes in the glenoid due to its degenerative nature, which leads to the erosion of joint surfaces. In the context of shoulder anatomy, particularly the glenoid—part of the shoulder joint—it can experience significant changes as a result of arthritis. This may include wear and loss of cartilage, bone remodeling, and the development of bone spurs, all of which contribute to altered joint biomechanics and may ultimately necessitate surgical intervention, such as total shoulder arthroplasty. These changes can lead to pain, loss of range of motion, and functional impairment, which are common symptoms associated with glenoid deformities caused by arthritis.
