Retrospective review of over 200 patients treated with small AO external fixators since 1979.
Detailed description of five specific clinical applications.
Analysis of treatment outcomes and complication rates.

Main Results:

The small AO external fixator demonstrated efficacy in treating fracture dislocations of the wrist, Kienböck's disease, bone defects, and basilar thumb metacarpal fractures.
Specific techniques and treatment protocols were refined over the study period.
Personal results indicate successful management with careful application.

Conclusions:

The small AO external fixator is a valuable tool for complex wrist and hand conditions.
Understanding specific indications and techniques is crucial for optimal outcomes.
Adherence to recommendations can minimize the risk of complications.
