Application
Preparation of the site to be fused and the specific
techniques are fairly similar regardless of where
the fusion is desired. The larger Spider plate’s
design is optimized for four-corner limited arthrodesis.
The plate can also be utilized for other limited
wrist fusion procedures for which the plate is
appropriately sized.
