Finger Size Assessment


Finger size is an objective measure of soft tissue over growth. It can be used to follow the response to treatment in Acromegaly.


Measurement should be between 0900h and 1000h before any intravenous cannula is inserted. Ring size is assessed on the proximal surface of the proximal interphalangeal joint of the fourth finger. The size is that of the tightest fit. A recording is made from each hand and clearly recorded in the notes. If the finger is too large for size Z then the fifth finger is used.
