OBJECTIVE: To functionally and oncologically assess the treatment of GCT on radius distal end (stage B3) following wide resection and reconstruction with avascular autologous graft from proximal fibular end. METHODS: The residual function was assessed using ISOLS score, measurement of the global residual arch of the operated wrist, residual percentage of the hand apprehension strength between thumb and index fingers. The oncologic monitoring was assessed by clinical examination of the operated limb and by imaging tests of the wrist and thorax. RESULTS: 17 patients were assessed: 10 females (58.8%) and seven males (41.2%), with aged ranging from 16 to 61 years (mean: 32.3 years), all of them right-handed. On the functional assessment (ISOLS), the results were as follows: 11 excellent, two good, and one poor. The three cases requiring arthrodesis evolved with excellent scores. The global residual arch was 196.2 ± 116.6º. The residual arch of the operated wrist corresponded to 58.9% of the control. The "pinch" percentage was 80.6 ± 14.8 % of control. We did not find recurrences or metastasis in this case series. CONCLUSION: This technique provided encouraging functional results, assuring patients' return to their usual activities. The absence of local recurrence and/or metastasis found even in the patients with longer follow-up times allow us to suggest this technique, which seems to be safe for oncologic control of the tumor.
