The splint shown in the picture above represents Dorsal extension block splint.
DORSAL EXTENSION BLOCK SPLINT
Common Uses. Larger, middle phalangeal volar avulsions with potential for dorsal subluxation; reduced, stable PIP joint dorsal dislocations.
Application. In reduced, volar avulsion fractures, the splint is applied with the PIP joint at 45 degrees of flexion and secured at the proximal finger, allowing flexion at
the PIP joint. With weekly lateral radiography, the flexion is decreased 15 degrees until reaching full extension over four weeks. Buddy taping should follow. Treatment of reduced PIP joint dislocations is similar, but requires a starting angle of 20 degrees.
