Objective:
To describe a novel method to reconstruct, with a vascularized rotational tibiaplasty, a complex femoral defect in an adolescent.
Methods:
After a femoral osteosarcoma resection, allograft reconstruction, and chemotherapy, an 11-year-old girl developed recurrent thigh wound infections and femoral allograft osteomyelitis despite multiple operative interventions. At the age of 13, she presented to our center with a complex right thigh wound and an unstable lower extremity secondary to a segmental femoral loss. To reestablish thigh stability and function and to avoid amputation at the hip, the authors performed a rotational vascularized tibiaplasty. The tibia was rotated 180° with the pivot at the knee. The distal tibia was internally stabilized to the residual proximal femur.
Results:
Ten years later, the patient had a stable thigh, a functional hip, no evidence of infection or sarcoma, and a Toronto Extremity Salvage Score of 92.5 (minimal disability).
Conclusions:
In this patient, the tibial rotationplasty provided a vascularized bone strut mimicking the resected femur; saved the hip; obviated an allograft bone; and created a functional, biologic, stable, and durable thigh that allowed full weight bearing on a prosthesis, with a low physical disability level. We conclude that, for patients with complex femoral defects, a vascularized rotational tibiaplasty should be considered a feasible option before amputation.
