===Treatment===
 
* Nondisplaced without angulation:
 
** Buddy tape to adjacent finger
 
*** Buddy tape ring finger to little finger
 
** Dorsal or volar finger splint if desire added protection
 
* Displaced or angulated fx
 
** Closed reduction
 
*** Adequate reduction:
 
**** <1-2mm displacement or shortening
 
**** Up to 10 degrees of angulation
 
**** No amount rotation
 
*** Followed by ulnar or radial gutter splint
 
**** Wrist in 20-30 degrees of extension
 
**** MCP joints in 70-90 degrees of flexion
 
**** PIP and DIP joints flexed 5-10 degrees
 
***** Decreases the force exerted by the FDS
 
 
 
===Dispo===
 
* Refer for:
 
** Comminution
 
** Malrotation
 
** Intraarticular fx
 
** Displaced or angulated fractures that cannot maintain their reduction
 
** Most spiral and oblique fx (usually involve rotation or shortening and are unstable)

===Examination===

===Imaging===
 
* Comminuted tuft fx
 
** Stable
 
* Longitudinal fx
 
** Usually non-displaced and stable
 
* Transverse fx
 
** Evaluate for angulation/displacement
 
* Intraarticular fx
 
 
 
===Treatment===
 
* Nondisplaced: Splint with the DIP joint in extension (splint should extend past the tip of the distal phalanx
 
** Do not attempt to reduce comminuted tuft fx
 
 
 
===Dispo===
 
* Refer for:
 
** Tendon dysfunction
 
** Nerve dysfunction
 
** Displacement or angulation
 
** Intraarticular fx
