Use of calcium phosphate cement for bone defect after harvesting radial forearm osteocutaneous flap.
To resolve esthetic and psychologic discomfort of patient due to the lack of radius after harvesting radial forearm osteocutaneous flap, we filled the bone defect and recreated its contour using calcium phosphate cement (CPC; Biopex; Mitsubishi Material Corporation, Tokyo, Japan). Injection of CPC was performed in 5 patients (3 women and 2 men). The patients' age ranged from 61 to 72 years (mean, 65 years), and the follow-up period ranged from 8 to 18 months. The size of the radius harvested varied from 10 x 35 mm to 10 x 50 mm. The width of the harvested bone was approximately 25% to 35% of the circumference of radius. Injected CPC volume varied from 3 to 4 mL, approximately. There was no postoperative infection or allergic reaction in any patient, and movement of hand was also with no problem. The X-P findings showed that the bone defect was filled with a uniform, high-density mass. The injected cement reduced in volume gradually during the fourth or fifth postoperative months, but the degree of reduction was mild in any case, which is probably less than 5% of the injected amount, allowing successful recreation of the contour of the radius. We conclude that the use of CPC for filling the defect of the bone donor site after harvesting radial osteocutaneous flap is valid method to keep a patient free from esthetic and psychologic discomfort due to the lack of the radius.
