Complications
Carpal Tunnel Syndrome
Theories
4CA bonegraft in carpal tunnel
immobilisation (subclinical CRPS, less nervegliding)
PRC shorter carpal tunnel is less length to compress?
EAROM = nerve gliding
Any suggestions ?

What have we learned ?
We no longer perform 4CA
What do we do with SLAC 3
wrists in young patients doing heavy labour?
variation of 3CA using shortening capitolunate fusion
(Herbert screw, no bonegraft, 3 weeks casting, preserves original radiolunate joint, avoids ulnocarpal impingement)
