4Option 2: Immobilization with a forearm cast and finger splint

A standard forearm cast including the wrist joint in 30 degrees of extension is applied.

Correct bending of the aluminium splint and correct fixation of the splint in the cast are difficult but essential. The bend for the flexion of the MCP joint is more proximal than often perceived. There is a risk of excessive pressure and later ulceration of the soft tissues at the level of the bend if it is too distal.

The advantage of this technique is that only the injured finger is immobilized. Usually hand therapy is not necessary.
Another advantage is that this technique helps maintain length in shortened fractures, but there is less control over rotation than with immobilisation of the adjacent rays (Option 1).
