Abstract
Arthroscopy-assisted partial wrist-fusion techniques are becoming more popular nowadays.
It became clearer that avoiding the violation of important ligament and tendinous
structures – which is impossible when using the classic open techniques – enables
a more biological approach, which is essential for faster healing and improvement
in function. We describe the use of the triquetrum-hamate (TH) portal, which is seldomly
applied in routine arthroscopic techniques for hand and wrist surgery, as an accessory
portal to better perform anterior midcarpal debridement in four-corner fusion. This
trick enables an almost complete anterior resection of the capitate and hamate chondral
surfaces, increasing the subchondral osseous contact in the midcarpal joint after
fixation, thus leading to higher consolidation rates.
