Deformity following Type III AC joint injury

Deformity following Type III AC joint injury
This 65-year-old masters cyclist and professional trombone player reports full, pain-free function after AC injury suffered when a dog ran out in front of him while cycling. Note the intact trapezius and anterior deltoid insertion on the clavicle, and drooped shoulder rather than elevated clavicle in the chronic state.
AC: acromioclavicular.
