Abstract:
Coracoclavicular joint (CCJ) is a rare cause of shoulder pain. CCJ is not described in most orthopaedic textbooks, leading to lack of awareness in the general orthopaedic community. In that way the incidence of symptomatic cases is underestimated. We present the case of a symptomatic osteoarthtritic CCJ in a 46-year-old male patient with nearly complete relief of pain after therapeutic injection of the CCJ. The radiological signs of CCJ are briefly discussed to increase awareness of this very rare entity.
