PENA MARRERO, Liván et al. Giant-cell tumor of the fibula and common peroneal nerve palsy. Rev Cubana Ortop Traumatol [online]. 2013, vol.27, n.2, pp. 209-218. ISSN 0864-215X.

Tumors of the fibula constitute a mere 2.5 % of the primary tumors of bone, and only one third of them are benign. Giant-cell tumors are a benign lesion, but their behavior may be locally aggressive. This case presentation is aimed at describing the successful treatment of a giant-cell tumor. A 30-year-old male patient with an imaging and histological diagnosis of a giant-cell tumor of the proximal end of the fibula presents with compressive common peroneal nerve palsy. En bloc resection of the proximal end of the fibula and release of the peroneal nerve were performed. The tumor was large. Though there was no infiltration into the neighboring soft tissues, cortical rupture had already occurred. Thus, the tumor was classified as grade III. After two months of rehabilitation, mobility and stability of the knee were normal. Nerve function was recovered 5 months after surgery. At 15 months there were no clinical or imaging signs of tumor recurrence. Grade III classification and location were the two criteria leading to the choice of en bloc resection. This surgical technique enables extraction of the tumor without excessive traction tension on the common peroneal nerve. The patient has fully reintegrated to his work and personal life.
