Acromioclavicular arthritis


The main aetiology of AC Arthritis is overuse of the shoulder in ageing individuals and active sportsmen/women. Weightlifters, other athletes or workers who repeatedly lift heavy weight with overhead movement are particularly prone to develop AC arthritis. It can also develop as a degenerative pathology following bone injury. Pre-existing, congenital autoimmune arthritis can include, amongst other joints, also the deterioration of the AC joint.
