A 65-year-old woman, who had been suffering from erosive rheumatoid arthritis, presented with swollen shoulders. Also, she experienced a weary feeling in her left arm. An MRI scan of the left shoulder showed multiple nodules ('rice bodies') in the subacromial-subdeltoid bursa. We extracted the nodules via a deltopectoral approach, after which the symptoms disappeared.

A 26-year-old male complained of painful clavicles. His medical history included multiple fractures of both clavicles, all treated conservatively. Conventional radiographs revealed a typical shape of both clavicles, suggesting non-union. His extraordinary medical history and non-union of both clavicles led to the diagnosis: 'congenital pseudarthrosis of both clavicles'.

A 24-year-old woman with Ehlers-Danlos syndrome visited the emergency department because of a post-traumatic painful and swollen left elbow with impaired function. A plain radiograph showed chronic luxation of the radial head with impression in the humeral capitellum. The clinical presentation of chronic luxation of the radial head is easily confused with that of an acute dislocation of the radial head, which may wrongly result in subsequent reduction.

An 18-year-old man presented with the inability of pro- and supination of the right forearm. Radiographic examination of the elbow showed a radioulnar synostosis. The degree of fixation of pronation of the forearm determines the functional complaints. In this case, the patient had a favourable pronation of 5 degrees, which allowed for conservative treatment.
