Extension block K-wire

A K-wire is introduced between the condyles of the proximal phalanx, in order to block the last 20-30 degrees of extension, but allowing full flexion.
This prevents dorsal subluxation and allows for immediate mobilization of the PIP joint.
This K-wire should be removed after 3-4 weeks.
