1 Introduction topenlarge
As this is an intraarticular fracture, there should be a low threshold for articular reconstruction with either K-wire or screw osteosynthesis.
In the presence of anatomical alignment, and no evidence articular incongruity, treatment with a simple splint may be inadequate and a short arm cast is more comfortable.
2 Short arm cast topenlarge
The majority of these fractures can be managed with a short arm cast. The operator should determine the stability of the fracture. If it is unstable with a tendency to displace a long arm cast is preferred. The purpose of the cast is to provide symptomatic relief during the period of fracture healing.
Note: In young, small, or noncompliant patients, it is safer to apply a long arm cast.
Splitting the cast
If a complete cast is applied in the acute phase after injury, it is safer to split the cast down to skin over its full length.
