Use of the "S" Quattro dynamic external fixator in the treatment of difficult hand fractures.

Thirty-seven patients were treated over a 7-year period using the "S" Quattro dynamic external fixator. There were 30 intra-articular and nine extra-articular fractures. Patients were reviewed at an average of 22.5 months. The average total range of motion for the affected digit at follow-up was 232 degrees for intra-articular and 241 degrees for extra-articular fractures. We believe that this device is a simple, reliable technique in the treatment of these difficult fractures.
