Background: To determine the clinical and radiographic results of hip arthrodesis using external with minimal internal fixation. Methods: A consecutive series of ten patients underwent hip arthrodesis using combined multi planar external fixation and transarticular screws. Operative parameters and radiographic and clinical results were retrospectively analyzed for each patient. Results: Mean estimated blood loss was 490 mL. At an average follow-up of 47.5 months, Harris Hip Score averaged 83.4. Mean postoperative measurements included anatomic axis hip adduction of 9°, hip flexion 22.2°, and leg length discrepancy 20.3 mm. Average adduction drift of 8.3° was noted after fixator removal. There were no nonunions. Conclusion: The described technique for hip arthrodesis reliably fused the hip in a favorable position requiring a less invasive approach with lower blood loss. Additional advantages include multiplanar stability, potential for hip position adjustment postoperatively and preservation of hip abductors; in case of future hip replacement. Level of Evidence: This was a Level IV, case series.
