Post-traumatic osteolysis of the distal end of the clavicle is a rare condition. It was first described by Dupas in 1936, and so far the total number of recoded cases is about a hundred. This condition is characterized by erosion and progressive resorption of the distal end of the clavicle following trauma. The interval between physical insult and radiographical recognition is from several weeks to several months. No more than 3 cm of bone have been lost in any recorded case, and remnants of bone may remain between the acromion and the clavicle. The usual symptoms are pain and restricted range of motion of the shoulder.
The etiology of the osteolytic process is uncertain. Osteoclastic resorption, nervous system dysfunction, vascular compromise, and arising from the synovium have all been hypothesized.
Now we will report a case of this condition.
