STT Fusion
Technique of STT Fusion (For Keinbock’s Disease)

- the exposure is a transverse incision
- the initial interval goes between EPL and ECRB
- watch out for superficial branch of the radial nerve
- take EPL radially first to deal with the scaphoid and trapezoid
- then take EPL ulnarly to deal with the trapezium, which is quite deep in the wound
- take off the radial styloid if doing it for SLAC wrist
- K-wire trapezoid to scaphoid - don’t actually need to K-wire to trapezium
