Abstract
- Purpose
Giant cell tumor (GCT) of the proximal femur is relatively rare, with only a few case series reported thus far. This study aimed to evaluate the clinical outcomes of GCT of the proximal femur treated with intralesional curettage and expand the understanding of their characteristics and treatment considerations.
Materials and Methods
Fifteen cases treated with curettage for GCT of the proximal femur between 2007 and 2020 were reviewed. The median follow-up was 46 months (25–150 months). There were 10 males and 5 females with a median age of 26 years (17–71 years). After curettage, the bone defect was filled with either an allograft (7 cases) or bone cement (8 cases).
Results
The postoperative complications were local recurrences in three cases (20.0%), including malignant transformation in one case and a femur neck fracture in one case (6.7%) following curettage and strut allograft. Among the 15 cases, 13 (86.7%) retained their native joint at the last follow-up. No patients developed degenerative changes or osteonecrosis.
Conclusion
The results of proximal femoral GCT with curettage were acceptable despite local recurrences in three cases (20.0%), and femur neck fracture in one case. An appropriate surgical approach and reconstruction according to the extent of the lesion are necessary for successful treatment.
