DOUBLE FEMORAL OSTEOTOMY FOR THE TREATMENT OF SEVERE SEQUELAE OF THE IMMATURE HIP.

OBJECTIVE

To evaluate the results of double femoral osteotomy for the treatment of severe sequelae of the hip.

METHODS

Immature patients with anatomical loss of the hip were treated with pelvic support osteotomy in the distal femur to correct lower limb shortening, they were evaluated clinically and radiographically.

RESULTS

Eleven cases (eleven hips) were assessed with verage follow-up of three years. The mean age of the patients was 14.7 years. Seven patients had sequela of infectious arthritis; three had sequela of developmental dysplasia of the hip and one patient had a sequela of slipped capital femoral epiphysis. Preoperatively, the gluteus medius was insufficient in all patients, and it became negative in ten of them. The average of lower limb shortening was 5 cm (2.5 to 7 cm) and reduced shortening was 1.9 cm (0 to 4 cm). According to Paley Classification, 72.7% of complications were considered problems, 90.9% were considered obstacles and 27.2% complications, among which the limitation of the knee flexion was the most frequent.

CONCLUSION

The technique yielded good results, considering the severity of the sequela and the absence of a better therapeutic option. No important sequela was associated with the treatment.
