We assessed three children who had limb salvage surgery for sarcomata of the proximal fibula. Their ages ranged from 6 to 13 years. MRI showed involvement of the anterior, lateral and deep posterior compartments. Incisional biopsy showed two osteoblastic osteosarcomata and one Ewing’s sarcoma. Preoperative angiogram confirmed that the tibialis posterior artery was the main blood supply to the foot.

The surgical technique was as described by Malawer (1984): via an anterolateral incision, the anterior, lateral and deep posterior compartments were excised en bloc with the proximal fibula. The peroneal artery was sacrificed in all three patients, and the common peroneal nerve and tibialis anterior artery in two. In the patient with Ewing’s sarcoma, the tibialis anterior muscle, artery and nerve did not require excision. What remained were the tibialis posterior nerve and artery, gastrocnemius, flexor digitorum longus and most of soleus. The lateral gastrocnemius was rotated forward to fill the defect. The collateral ligament of the knee was reconstructed by suturing the lateral collateral ligament and biceps femoris to the proximal tibia.

All three patients had neo-adjuvant chemotherapy. Tumour necrosis ranged from 90% to 100%.

At follow-up at 2, 4 and 9 years, there was no recurrence. The Musculoskeletal Tumour Society evaluation was used and all patients scored more than 80% and were happy with the cosmetic result. Although two of the three patients required an orthotic because of weak dorsiflexion, the functional result was good.
