We report a case of benign giant cell tumour which over a 20-year period has given rise to pulmonary and bony metastases. The indolent nature of these metastases is remarkable, with considerable implications for the long-term management of such cases.

The treatment of acromioclavicular injuries is controversial; few studies document the late results. We have reviewed 53 patients about five years after conservative management, in nine for subluxation and 44 for dislocation. Subjective and objective results were satisfactory in all cases except for one with painful subluxation, who was the only patient to change her occupation because of the injury. At review, joint stability was demonstrated by improvement in position and by the very small increase in the coracoclavicular gap on stress radiographs.
