Periacetabular limb salvage for malignant bone tumours

Area of Science:

• Orthopedic Oncology
• Surgical Oncology
• Bone Tumors

Background:

• Malignant periacetabular bone tumors present complex surgical challenges.
• Limb salvage surgery aims to preserve function while removing tumors.

Purpose of the Study:

• To evaluate treatment outcomes for malignant periacetabular bone tumor removal and limb salvage.
• To compare outcomes with and without bone-graft reconstruction.

Main Methods:

• Retrospective analysis of 13 patients with malignant periacetabular bone tumors.
• Tumor resection with limb salvage, with or without fibular bone graft reconstruction.
• Adjuvant chemotherapy and radiation therapy as indicated.

Main Results:

• 9 of 13 patients were disease-free at a mean follow-up of 24.3 months.
• Mean Musculoskeletal Tumor Society functional score was 68.7%.
• Leg-length discrepancies (3-10 cm) occurred in patients after internal hemipelvectomy.

Conclusions:

• Malignant periacetabular tumors are challenging to manage.
• Fair functional results were observed with or without bone-graft reconstruction.
• Leg-length discrepancies post-hemipelvectomy can be managed with shoe lifts.
