3Option 1: Immobilization with palmar splint

A splint may be applied with the hand in an intrinsic plus position and the wrist in slight extension.

A splint may be applied with the hand in an intrinsic plus (Edinburgh) position and the wrist in slight extension of 20-30 degrees.

In compliant patients, only the fractured finger ray and the two adjacent rays are included in the splint, in fractures of the third, or fourth, metacarpal. In fractures of the second metacarpal, it may be sufficient to include only the second and third rays. In fractures of the fifth metacarpal, the fifth and fourth rays are included.
The splint is held in place with an elastic bandage. The bandage should not be overtightened at the level of the wrist joint, so as to avoid excessive swelling of the hand.

Direct skin contact of adjacent fingers should be prevented by placing gauze pads between them.
This splint is easy to apply and needs no hand therapy during the period of immobilization. A potential disadvantage of this technique is the complete immobilization of uninjured fingers and joints.
