The study aims to collect the clinical activity and management data of the Orthogeriatrics and Orthopedics Units participating in the study on a continuous and long-term basis. By collecting clinical data and comparing the performance of the various centers, the study aims to guide the participating centers towards the principles of good clinical practice in orthogeriatrics.

Multicenter prospective cohort observational study. The enrollment period will be 5 years. An additional 4 months will be required to allow the last enrolled patients to complete the 120-day follow-up. It is estimated to enroll a total of 7,000 patients. To facilitate the participation in the study of non-university or IRCCS assistance departments, two methods of data collection will be possible:

• High intensity: continuous data collection for the whole period of the study on all the incident cases
• Low intensity: data collection once a year on incident cases over a continuous period of 1 month, with a reduced number of variables.

The choice of the level of intensity with regard to the data collection method will take place on a voluntary basis (each OU will actually choose the type of speed with which it intends to collaborate in the project, after communicating to the steering committee and to the biostatisticians of the study)
