Fractures at the base of the thumb.

The details of the basal joint anatomic complex must be understood if fractures in this area are to be classified and treated properly. The specifics have been reviewed and treatment principles emphasized. Most injuries respond to closed reduction and external immobilization, often with supplemental percutaneous internal fixation. Occasionally, for specific indications, open reduction will be necessary. Fortunately with carefully selected treatment, results from fractures in this area are usually favorable.
