Abstract |
Bone remodeling commonly occurred after fracture and curettage benign bone tumor. A lot of previous articles reported “internal” trabecular bone remodeling. There were no previous clinical reports about “external” cortical bone remodeling. We present here 2 clinical cases of “external” bone remodeling after injectable calcium-phosphate in benign bone tumor in the hand. In two cases of benign bone tumor, we performed complete removal of the tumor and immediate filling of the metacarpal bone with injectable calcium-phosphate cement Arexbone® from the mechanical viewpoint. With respect to the shape of the calcium-phosphate, by using an injection-type, calcium-phosphate is adhered uniformly to the bone cortex by injecting, remodeling has been promoted. After 5 and 8years, both cases were no recurrences, and the shape of the metacarpal looked close to the contralateral side. These findings supposed to be concerned with potential self-healing and self-protection mechanism in human body.
