Re: Bulic K. Wassel type IV thumb duplication. A case of mistaken identity? J Hand Surg Eur. 2008, 33: 536-7

摘要

I read this report with interest. The point that a discrepancy exists between the definition and the diagram of the Wassel (1969) classification of the type IV thumb duplication has been previously described by Light (1992). Light (1992) proposed a modified classification for the original Wassel (1969) classification scheme and paid special attention to the above mentioned point. He proposed and illustrated the hand depicted by Wassel (1969) as type IV would be classified as a type IIIB thumb. I think that the respected author was not aware of Light's (1992) work, so did not make reference to him.
