Brief summary

The purpose of the study is to investigate how high the prevalence of diabetes (known and unknown) is among patients with a frozen shoulder. Our hypothesis is that it is around 30-40 %. Another purpose is to investigate whether patients with diabetes have a worse and more painful frozen shoulder than patients without diabetes, and whether the diabetes have an influence on the prognosis.

Detailed description

Patients who are not diagnosed with diabetes would be ask to give a blood sample to investigate if they have an unknown diabetes. All patients with frozen shoulder will be asked to fill out a questionnaire (Oxford Shoulder Score) to clarify how bad their frozen shoulder is. All patients will receive the questionnaire 6 and 24 month following the date on inclusion.
