Patients with calcific tendinitis and large calcium lumps can be treated with an arthroscopic excision of the calcium deposit. This may also be performed in conjunction with an acromioplasty.
The region of tendon with the calcium inside it can usually be identified by the visualisation of an inflamed area of tendon. The location can be confirmed by probing the tendon with a needle until calcium is seen in the tip of the needle. Once the calcium is located a small longitudinal incision is made in the tendon in line with its fibres and the calcium removed with an arthroscopic shaver and curette.
