Osteoscopic Surgery of Giant Cell Tumor of Bone for Preservation of Proximal Fibula

Anticancer Res. 2018 May;38(5):2995-3000. doi: 10.21873/anticanres.12552.


Background: Osteoscopy is a minimally-invasive endoscopic technique for inspecting lesions inside bone marrow cavities. We describe the feasibility of osteoscopic surgery of giant cell tumor of bone (GCTB) in order to preserve the proximal fibula, and thereby achieve immediate recovery and avoid complications.

Patients and methods: Five patients with GCTB in the proximal fibula were treated using osteoscopic curettage with adjuvants (argon plasma coagulation and cementation). Functional outcome was evaluated by knee stability, Musculoskeletal Tumor Society (MSTS) rating, and Tegner score. Oncological outcome was evaluated for local recurrence and pulmonary metastasis.

Results: Regarding functional outcome, knee instability was negative in all cases. Mean MSTS rating was 100%. Tegner scores were the same as those prior to surgery. Neither local recurrence nor pulmonary metastasis were found.

Conclusion: Osteoscopic surgery is feasible for immediate and complete recovery, and can improve quality of life for patients with GCTB of the proximal fibula with satisfactory oncological outcome.
