In France, there is currently no data to directly estimate the number of bilateral upper limb amputations, their characteristics and therapeutic care.

By extrapolation from the Regional Institute of Physical Medicine and Rehabilitation (PMR) Nancy in 2005, the number of new cases of amputated patients with prosthetic fitting of the upper limb was estimated at 355. Epidemiological data from the 2009-2010 Annual Report of the LIMBLESS STATISTICS database (collection of quantitative clinical data and demographic of amputees patients referred by orthopaedic centres in the United Kingdom , whose population's characteristics are similar to France) identified 395 incident cases of upper limb amputation with, 6 bilateral amputations observed. The causes are varied: traumatic, infectious or related to diabetes. The population was relatively young, aged between 15 and 54 year old.

On this basis, the estimated number of new cases of bilateral upper limb amputations throughout France should therefore be about 40 incident cases over a 5-year period.

This observational study is aimed at collecting comprehensive and high quality data to describe the French population of bilateral upper limb amputees.

• who have given their non-opposition to participate in the study.

Exclusion Criteria:
