Objective:
To study the effect and complication of repairing depressed fracture of frontal part with hydroxylapatite particulate artificial bone.
Methods:
From January 1994 to December 2002, 13 patients were all diagnosed as having depressed fracture of frontal part with clinical and X-ray examinations. The small incision before the hair-edge or local small incision was made. After opening the incision, we performed creeping decollement. Then the hydroxylapatite particulate artificial bone was implanted into the sites of the depressed fracture. The effect and complication were observed with clinical and X-ray examinations in all patients 1 week, 1 month, 3 months after operation.
Results:
The quantity of hydroxylapatite implanted was 10-30 g. Primary healing was obtained in all cases without any complication. All cases were followed up for 3 months. The contours of the frontal part were restored well.
Conclusion:
It is a good method to repair depressed fracture of frontal part with hydroxylapatite particulate artificial bone.
