Objective:
To study the effect of self-setting calcium phosphate cement (CPC) on the repair of local bone defects after resection of cyst in children.
Methods:
From December 1998 to May 2002, 22 patients with bone defects were repaired with CPC. Their ages ranged from 4 to 10 years with an average of 8.3 years. There were 11 cases of non-ossifying fibroma, 7 cases of osteoid osteoma, 2 cases of bone cyst and 2 cases of fibrous dysplasia. The bone defects are located as the following: femur in 14 cases, tibia in 6 cases and humerus in 2 cases. CPC spongiosa granules were filled in 11 cases, injectable CPC were filled in 2 bone cyst cases. The patients were followed up for 5-48 months, averaged 23.5 months.
Results:
Bone matrix grew well and no recurrence was found.
Conclusion:
The method with simple CPC in repairing bone defects is safe, non-toxic, economic and convenient in children.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
