*1: High level of QuickDASH score was induced by bilateral radius fracture.
*2: High level of QuickDASH score was probably induced by CRPS type 2 after the operation.
*3: Residual pain and high level of QuickDASH score were induced by polyarthritis.
*4: High level of QuickDASH score was induced by progressive degenerative brain disease (probably Alzheimer disease).
Cases 7, 8, and 12: Latest consultation was performed by telephone interview.
