Introduction – To reach the best oncological perspective in intra-articular, periacetabular- and/or proximal femur tumors, a radical extra-articular periacetabular resection is necessary. In this case report we present an extra-articular periacetabular resection technique through a posterolateral approach to the hip. This surgical technique is relatively unknown in tumor surgery of Enneking type II lesions.
Cases – Three patients with malignant tumor growth in the hip joint were treated with a wide, extra-articular resection of the hip joint, conducted through a posterolateral approach. Reconstruction was realized in 2 cases with a Burch-Schneider reinforcement cage, in the other case with a LUMIC prosthesis. In all three cases, the short follow-up showed excellent functional outcome and only one minor complication; a subcutaneous hematoma for which transfusion was necessary.
Conclusion – This approach to the hip joint shows promising results in treating tumors of the periacetabular region. Further research to discover long term functional outcomes is necessary.
