[Low-cost reconstructive treatment after resection of distal radius giant cell tumor].

Abstract

Introduction: giant cell tumor (GCT) is a benign intramedullary bone tumor that frequently arises at the ends of long bones. After the distal femur and proximal tibia, the distal radius is the third most affected site with particularly aggressive tumors. Our objective is the presentation of the clinical case of a patient diagnosed with distal radius GCT classified in grade III of Campanacci who received a treatment adjusted to her economic possibilities.

Case report: a 47-year-old female, without economic solvency and with some medical service. Treatment included block resection, reconstruction with distal fibula autograft, and radiocarpal fusion with blocked compression plate. Eighteen months later, the patient had good grip strength (80% on the healthy side) and had fine motor function in the hand. The wrist presented stability with pronation of 85o, supination of 80o, flexion-extension of 0o and a score of 6.7 in the DASH functional outcomes assessment questionnaire. His radiological evaluation five years after his surgery continued with no evidence of local recurrence and pulmonary involvement.

Conclusion: the result in this patient, together with the published data, indicate that the block tumor resection technique, plus distal fibula autograft and arthrodesis with blocked compression plate provide an optimal result of functionality for the grade III distal radial tumor at low cost.
