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" Quatt ro dynamic external fixator. There were 30 intra-articular and nine extra-a rticular fractures. Patients were reviewed at an average of 22.5 months. Th e average total range of motion for the affected digit at follow-up nas 232 degrees for intra-articular and 241 degrees for extra-articular fractures. We believe that this device is a simple, reliable technique in the treatme nt of these difficult fractures.
