Calcific tendonitis

The tendons, especially the supraspinatus, lack adequate circulation at the area where a gap occurs between vessels entering the tendon from the muscle and vessels entering from the bone. This area is known as the critical zone. The critical zone is also the most likely site of deposition of calcium in calcific tendonitis. Calcium deposits in the tendon, calcific tendonitis, may become chronic and delay recovery from the tendonitis.

Minimal skeletal hyperostosis and calcification of ligaments and tendons has been observed by x-ray in prospective studies of nodular acne patients treated with a single course of therapy at recommended doses. The skeletal effects of multiple isotretinoin treatment courses for acne are unknown.

Apart from causing a stimulation of osteoblastic activity the ingestion of excessive amounts of fluoride over long periods may lead to calcification of tendons, ligaments and occasionally muscles. The vertebrae, ribs and pelvis are more prone to the development of non-malignant... 

Pain is located over the epicondyl and radiates down the arm. It is aggravated by dorsi-flexion of the wrist while grasping an object or flexion ol the wrist against resistance. Calcification within the tendon may be seen in the area of degeneration. 

Plantar fascitis is an inflammation of the plantar fascia of the foot, usually at its insertion on the calcaneus. When chronic in nature, a calcification may develop at the site of insertion of the tendon and a diagnosis of a heel spur is made.
