摘要

Giant cell tumor of bone (GCTB) is classified as an intermediate malignant bone tumor, and occurrences in the distal ulna are particularly rare. This study aims to evaluate the outcomes of treating GCTB in the distal ulna through wide excision. We conducted a retrospective analysis at a single center, focusing on patients with GCTB of the distal ulna. The study included six nonmetastatic patients (5 males, 1 female; mean age 31 years, range 19–48 years) who underwent wide excision of the tumor without reconstruction. All patients followed a physiotherapy protocol. The mean follow-up period was 20 months, ranging from 12 to 54 months. Mean resection length was 8.3 cm. There were no cases of local recurrence and distal metastasis. At the latest follow-up, mean grip strength was 81% compared to the normal side, mean Modified Mayo wrist score was 83, and mean Patient Rated Wrist/Hand Evaluation (PRWHE) score was 23. Ulnar carpal translation was not present. For giant cell tumors of the distal ulna, we recommend en bloc excision with adequate margins, irrespective of Campanacci grade, without the necessity for reconstruction.
